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 vary across the complete power supply range (from VCCto VEE). 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.

These devices have been designed so that the ON resistance (Ron) is more linear over input voltage than Ronof metal−gate CMOS analog switches.

For a multiplexer/demultiplexer with injection current protection, see HC4851A and HCT4851A.
