Analog Multiplexers /
Demultiplexers
High−Performance Silicon−Gate CMOS
The MC74HC4051A, MC74HC4052A and MC74HC4053A 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−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.
These devices have been designed so that the ON resistance (Ron) is
more linear over input voltage than Ron of metal−gate CMOS analog
switches.
For a multiplexer/demultiplexer with injection current protection,
see HC4851A and HC4852A.
