TRI-STATE Data Selectors/Multiplexers

General Description

Each of these Schottky-clamped data selectors/multiplex-

ers contains inverters and drivers to supply fully comple-

mentary, on-chip, binary decoding data selection to the

AND-OR gates. Separate output control inputs are provided

for each of the two four-line sections.

Features

TRI-STATE version of LS153 with same pinout

Schottky-diode-clamped transistors

Permit multiplexing from N-lines to one line

Performs parallel-to-serial conversion

Strobe/output control

The TRI-STATE outputs can interface directly with data

lines of bus-organized systems. With all but one of the com-

mon outputs disabled (at a high impedance state), the low

impedance of the single enabled output will drive the bus

line to a high or low logic level.

High fanout totem-pole outputs

Typical propagation delay

Data to output 12 ns

Select to output 21 ns

Typical power dissipation 35 mW

Alternate Military/Aerospace device (54LS253) is avail-

able. Contact a National Semiconductor Sales Office/

Distributor for specifications.
