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
