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
Features
s Buffered inputs and outputs
s Typical propagation time 9 ns
s Typical power dissipation 150 mW
