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 across the full power–supply range (from VCC to GND).

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

resistances (RON) are much more linear over input voltage than RON

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 3.0V CMOS logic to

5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic

while operating at the higher–voltage power supply.

The MC74LVXT4066 input structure provides protection when voltages

up to 7V are applied, regardless of the supply voltage. This allows the

MC74LVXT4066 to be used to interface 5V circuits to 3V circuits.
