DM74157
Quad 2-Line to 1-Line Data Selectors/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.
Applications
Expand any data input point
Multiplex dual data buses
Generate four functions of two variables (one variable is
common)
Source programmable counters
