High–Performance Silicon–Gate CMOS
The MC74LVXT4066 utilizes silicon–gate CMOS technology to
achieve fast propagation delays, low ON resistances, and low

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 3.0V 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.
