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

of metal−gate CMOS analog switches.

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.
