Analog Multiplexers / Demultiplexers with LSTTL Compatible Inputs
High−Performance Silicon−Gate CMOS
MC74HCT4051A, MC74HCT4052A, MC74HCT4053A
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 VCC to 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.
