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