DM74LS353

Dual 4-Input Multiplexer with TRI-STATE

Outputs

General Description

The ’353 is a dual 4-input multiplexer with TRI-STATE out-

puts It can select two bits of data from four sources using

common select inputs The outputs may be individually

switched to a high impedance state with a HIGH on the

respective Output (OE) inputs allowing the outputs to inter-

face directly with bus oriented systems It is fabricated with

the Schottky barrier diode process for high speed and is

completely compatible with all National TTL families
