Analog Multiplexers/ Demultiplexers

High–Performance Silicon–Gate CMOS
The MC54/74HC4051, MC74HC4052 and MC54/74HC4053 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 HC4051, HC4052 and HC4053 are identical in pinout to the metal–gate MC14051B, MC14052B and MC14053B. 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.
