54153/DM54153/DM74153 Dual 4-Line to 1-Line Data Selectors/Multiplexers

General Description

Each of these data selectors/multiplexers contains invert­

ers and drivers to supply fully complementary, on-chip, bina­

ry decoding data selection to the AND-OR-invert gates.

Separate strobe inputs are provided for each of the two four-line sections.

Features

is Permits multiplexing from N lines to 1 line

■ Performs parallel-to-serial conversion

a Strobe (enable) line provided for cascading (N lines to n lines)

■ High fan-out, low-impedance, totem-pole outputs

■ Typical average propagation delay times From data 11 ns

From strobe 18 ns From select 20 ns

□ Typical power dissipation 170 mW

□ Alternate Military/Aerospace device (54153) is avail­

able. Contact a National Semiconductor Sales O ffice/

Distributor for specifications.
