MC74LVXT4066
Quad Analog Switch/
Multiplexer/Demultiplexer
High−Performance Silicon−Gate CMOS
The MC74LVXT4066 utilizes silicon−gate CMOS technology to
achieve fast propagation delays, low ON resistances, and low
OFF−channel leakage current. This bilateral switch/multiplexer/
demultiplexer controls analog and digital voltages that may vary

The LVXT4066 is identical in pinout to the metal−gate CMOS
MC14066 and the high−speed CMOS HC4066A. Each device has four
independent switches. The device has been designed so that the ON

The ON/OFF control inputs are compatible with standard LSTTL
outputs. The input protection circuitry on this device allows
overvoltage tolerance on the ON/OFF control inputs, allowing the
device to be used as a logic−level translator from 3.0 V CMOS logic to
5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V CMOS Logic
while operating at the higher−voltage power supply.
The MC74LVXT4066 input structure provides protection when
voltages up to 7.0 V are applied, regardless of the supply voltage. This
allows the MC74LVXT4066 to be used to interface 5.0 V circuits to
3.0 V circuits.
