DESCRIPTION
The MP2735/MP2736 are low voltage, low on-
resistance, dual single-pole/double-throw
(SPDT) monolithic CMOS analog switches
designed for high performance switching of
analog signals. Combining low-power, high
speed, low on-resistance, and small package
size, the MP2735/MP2736 are ideal for portable
and battery power applications.
The MP2735/MP2736 have an operation range
from 1.65V to 5.5V single supply. The MP2735
has two separate control pins and two separate
SPDT switches. The MP2736 includes an EN
pin. All switches are at high impedance mode
when the EN is high.
The MP2735/MP2736 are guaranteed 1.65V
logic compatible, allowing the easy interface
with low voltage DSP or MCU control logic and
ideal for one cell Li-ion battery direct power.

QUICK START GUIDE
1. Preset the power supply output to between 1.65V and 5.5V, then turn off the power supply.
2. Connect the positive and negative terminals of the power supply output to the V+ and GND
pins, respectively.
3. Turn the power supply on. The NC1 and NC2 channels will automatically turn on. NO1 and NO2
channels are open.
4. Drive IN1 or IN2 higher than 2.5V to turn on NO1 or NO2 channels respectively. Or drive IN1 or
IN2 less than 0.4V to turn on NC1 or NC2 channels.
