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. FEATURES
s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s Advanced oxide-isolated, ion-implanted Schottky TTL process s Functionally and pin for pin compatible with Schottky, low power Schottky, and advanced low power Schottky TTL counterpart s Improved AC performance over Schottky, low power Schottky, and advanced 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 Ordering Code: Order Number DM74AS157M DM74AS157SJX DM74AS157N DM74AS158M DM74AS158N Package Number M16A M16D N16E M16A N16E Package DESCRIPTION
