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.
