74HC4051A Overview
These analog multiplexers/ demultiplexers control analog voltages that may vary across the plete power supply range (from VCC to VEE). The HC4051A, HC4052A and HC4053A 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 mon Output/Input.
