Overview
DM74ALS157 • DM74ALS158 Quad 1-of-2 Line Data Selector/Multiplexer April 1984 Revised February 2000 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 output 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 vari...
