Quad 1-of-2 Line Data Selector/Multiplexer

General Description

Features

These data selectors/multiplexers contain inverters and

drivers to supply full on-chip data selection to the four out-

put gates. A separate strobe input is provided. A 4-bit word

is selected from one of two sources and is routed to the

four outputs. The ALS157 presents true data whereas the

ALS158 presents inverted data to minimize propagation

delay time.

■ Switching specifications at 50 pF

■ Switching specifications guaranteed over full tempera-

ture and V_CCrange

■ Advanced oxide-isolated, ion-implanted Schottky TTL

process

■ Functionally and pin for pin compatible with Schottky

and low power Schottky TTL counterpart

■ Improved AC performance over Schottky and low power

Schottky counterparts

■ Expand any data input point

■ Multiplex dual data buses

■ General four functions of two variables (one variable is

common)

■ Source programmable counters
