Analog Multiplexers/
Demultiplexers with
Address Latch
High−Performance Silicon−Gate CMOS
The MC54/74HC4351, and MC54/74HC4353 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 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. The data at the Channel−Select inputs may be
latched by using the active−low Latch Enable pin. When Latch Enable
is high, the latch is transparent. When either Enable 1 (active low) or
Enable 2 (active high) is inactive, 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 multiplexers/demultiplexers without latches, see the HC4051,
HC4052, and HC4053.
