SEMICONDUCTOR TECHNICAL DATA
High–Performance Silicon–Gate CMOS
The MC54/74HC4051A, MC74HC4052A and MC54/74HC4053A 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

The HC4051A, HC4052A and HC4053A are identical in pinout to the
metal–gate MC14051AB, MC14052AB and MC14053AB. The Channel–Se-
lect 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 outputs; with pullup resistors they are compatible with LSTTL
outputs.
