Compatible Inputs

High−Performance Silicon−Gate CMOS

The MC74HCT4051A, MC74HCT4052A and MC74HCT4053A

utilize silicon−gate CMOS technology to achieve fast propagation

delays, low ON resistances, and low OFF leakage currents. These

analog multiplexers/demultiplexers control analog voltages that may

The HCT4051A, HCT4052A and HCT4053A are identical in

pinout to the metal−gate MC14051AB, MC14052AB and

MC14053AB. The Channel−Select inputs determine which one of the

Analog Inputs/Outputs is to be connected, by means of an analog

switch, to the Common Output/Input. When the Enable pin is HIGH,

all analog switches are turned off.

The Channel−Select and Enable inputs are compatible with standard

CMOS and LSTTL outputs.
