DM74ALS157 • DM74ALS158
Quad 1-of-2 Line Data Selector/Multiplexer
General Description
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.
Features
s Switching specifications at 50 pF
s Switching specifications guaranteed over full tempera-
ture and VCC range
s Advanced oxide-isolated, ion-implanted Schottky TTL
process
s Functionally and pin for pin compatible with Schottky
and low power Schottky TTL counterpart
s Improved AC performance over Schottky and low power
Schottky counterparts
s Expand any data input point
s Multiplex dual data buses
s General four functions of two variables (one variable is
common)
s Source programmable counters
