Analog Multiplexers /
Demultiplexers with LSTTL
Compatible Inputs
High−Performance Silicon−Gate CMOS
The MC74HCT4051A, MC74HCT4052A and MC74HCT4053A
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 V
CC
to V
EE
).
The HCT4051A, HCT4052A and HCT4053A 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 and LSTTL outputs.
These devices have been designed so that the ON resistance (R
on
) is
more linear over input voltage than R
on
of metal−gate CMOS analog
switches.
For a multiplexer/demultiplexer with injection current protection,
see HC4851A and HCT4851A.
