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
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–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.
These devices have been designed so that the ON resistance (Ron) is
more linear over input voltage than R on of metal–gate CMOS analog
switches.
For a multiplexer/demultiplexer with channel–select latches, see
HC4351A.
