9322/DM9322 Quad 2-Line to 1-Line
Data Selectors/Multiplexers
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. True data is presented at the outputs.
