DESCRIPTION
The LCX244 is a low voltage CMOS OCTAL BUS
BUFFER (NON-INVERTED) fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology. It is ideal for low
power and high speed 3.3V applications; it can
be interfaced to 5V signal environment for both
T
(TSSOPPackage)
inputsandoutputs.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
This device is designed to be used with 3 state
memoryaddressdrivers, etc.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

2. 74VHC244
74VHC244
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The VHC244 is an advanced high speed CMOS octal bus
buffer fabricated with silicon gate CMOS technology. It
achieves high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation. The VHC244 is a non-inverting 3-STATE buffer hav-
ing two active-LOW output enables. These devices are
designed to be used as 3-STATE memory address drivers,
clock drivers, and bus oriented transmitter/receivers.
An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
Features
■High Speed: tPD =3.9ns (typ) at VCC =5V
■High noise immunity: VNIH =VNIL =28% VCC (min)
■Power down protection is provided on all inputs
■Low noise: VOLP =0.6V (typ)
■Low power dissipation: ICC =4 mA (max) @ TA=25°C
■Pin and function compatible with 74HC244
Ordering Code:
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter ìXî to the ordering code.

74VHCT244A
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The VHCT244A is an advanced high speed CMOS octal
bus transceiver fabricated with silicon gate CMOS technol-
ogy. It achieves high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low
power dissipation. The VHCT244A is a non-inverting 3-
STATE buffer having two active-LOW output enables. This
device is designed to be used as 3-STATE memory
address drivers, clock drivers, and bus oriented transmitter/
receivers.
Protection circuits ensure that 0V to 7V can be applied to
the input and output (Note 1) pins without regard to the
supply voltage. These circuits prevent device destruction
due to mismatched supply and input/output voltages. This
device can be used to interface 5V to 3V systems and two
supply systems such as battery back up.
Note 1: Outputs in OFF-State
Features
■High Speed: tPD =5.9 ns (typ) at VCC =5V
■Power down protection is provided on inputs and
outputs
■Low power dissipation: ICC =4 mA (max) @ TA=25°C
■Pin and function compatible with 74HCT244
