DM74AS157 • DM74AS158 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 AS157 presents true data whereas the AS158 presents inverted data to minimize propagation delay time.
