SN74LVC2G241 Dual Buffer and Driver With 3-State Outputs
1 Features 3 Description
This dual buffer and line driver is designed for 1.65-V
1• Available in the Texas Instruments to 5.5-V VCC operation.
NanoFree™ Package The SN74LVC2G241 device is designed specifically
• Supports 5-V VCC Operation to improve both the performance and density of 3-
• Inputs Accept Voltages to 5.5 V state memory-address drivers, clock drivers, and bus-
• Max tpd of 4.1 ns at 3.3 V oriented receivers and transmitters.
• Low Power Consumption, 10-µA Maximum ICC NanoFree package technology is a major
• ±24-mA Output Drive at 3.3 V breakthrough in IC packaging concepts, using the die
as the package.
• Typical VOLP (Output Ground Bounce)
<0.8 V at VCC = 3.3 V, TA= 25°C The SN74LVC2G241 device is organized as two 1-bit
• Typical VOHV (Output VOH Undershoot) line drivers with separate output-enable (1OE, 2OE)
>2 V at VCC = 3.3 V, TA= 25°C inputs. When 1OE is low and 2OE is high, the device
passes data from the A inputs to the Y outputs. When
• Ioff Supports Live Insertion, Partial-Power-Down 1OE is high and 2OE is low, the outputs are in the
Mode, and Back-Drive Protection high-impedance state.
• Can Be Used as a Down Translator to Translate To ensure the high-impedance state during power up
Inputs From a Max of 5.5 V Down or power down, OE should be tied to VCC through a
to the VCC Level pullup resistor, and OE should be tied to GND
• Latch-Up Performance Exceeds 100 mA Per through a pulldown resistor; the minimum value of the
JESD 78, Class II resistor is determined by the current-sinking or the
• ESD Protection Exceeds JESD 22 current-sourcing capability of the driver.
– 2000-V Human-Body Model (A114-A) This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables the
– 200-V Machine Model (A115-A) outputs, preventing damaging current backflow

8 Detailed Description
8.1 Overview
The SN74LVC2G241 device is designed specifically to improve both the performance and density of 3-state
memory-address drivers, clock drivers, and bus-oriented receivers and transmitters. The SN74LVC2G241 device
is organized as two 1-bit line drivers with separate output-enable (1OE, 2OE) inputs. When 1OE is low and 2OE
is high, the device passes data from the A inputs to the Y outputs. When 1OE is high and 2OE is low, the
outputs are in the high-impedance state.
The SN74LVC2G241 is also an effective redriver, with a maximum output current drive of 32 mA.
8.2 Functional Block Diagram
Figure 3. Logic Diagram (Positive Logic)
8.3 Feature Description
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor, and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is
determined by the current-sinking or the current-sourcing capability of the driver.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
Typical Application shows a simple application where a physical push button is connected to the
SN74LVC2G241. The push button is in a physical location far enough away from the processor that the input
signal is weak and needs to be redriven. The SN74LVC2G241 acts as a redriver, providing a strong input signal
to the processor with as little as 1 ns of propagation delay.
9.2 Typical Application
Figure 4. SN74LVC2G241 Application
9.2.1 Design Requirements
This device uses CMOS technology and has balanced output drive. Take care to avoid bus contention because it
can drive currents that would exceed maximum limits. The high drive also creates fast edges into light loads, so
routing and load conditions must be considered to prevent ringing.
9.2.2 Detailed Design Procedure
1. Recommended Input Conditions
– Rise time and fall time specs. See (Δt/ΔV) in Recommended Operating Conditions.
– Specified high and low levels. See (VIH and VIL)inRecommended Operating Conditions.
– Inputs are overvoltage tolerant allowing them to go as high as (VImax) in Recommended Operating
Conditions at any valid VCC.
2. Recommend Output Conditions
– Load currents must not exceed (IOmax) per output and must not exceed (Continuous current through VCC
or GND) total current for the part. These limits are located in Absolute Maximum Ratings.
– Outputs must not be pulled above VCC during normal operation or 5.5 V in high-z state.

10 Power Supply Recommendations
The power supply can be any voltage between the minimum and maximum supply voltage rating located in
Recommended Operating Conditions.
Each VCC pin should have a good bypass capacitor to prevent power disturbance. For devices with a single
supply, a 0.1-μF capacitor is recommended and if there are multiple VCC pins then a 0.01-μF or 0.022-μF
capacitor is recommended for each power pin. It is ok to parallel multiple bypass capacitors to reject different
frequencies of noise. 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be
installed as close to the power pin as possible for best results.
11 Layout
11.1 Layout Guidelines
When using multiple bit logic devices inputs must not ever float. In many cases, functions or parts of functions of
digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or only 3
of the 4 buffer gates are used. Such input pins must not be left unconnected because the undefined voltages at
the outside connections result in undefined operational states. Specified below are the rules that must be
observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low
bias to prevent them from floating. The logic level that should be applied to any particular unused input depends
on the function of the device. Generally they will be tied to GND or VCC, whichever make more sense or is more
convenient.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.
