SEMICONDUCTOR TECHNICAL DATA
High–Performance Silicon–Gate CMOS
The MC54/74HC4051, MC74HC4052 and MC54/74HC4053 utilize sili-
con–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 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.

The Channel–Select and Enable inputs are compatible with standard
CMOS outputs; with pullup resistors they are compatible with LSTTL
outputs.
