A20032 - 74S158PC Quad Data Selector/Multiplexer (Fairchild)

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 74S158PC presents inverted data to minimize propagation delay time.

Features:
Buffered inputs and outputs
Typical propagation time: 4 ns
Typical power dissipation: 195 mW

Applications:
Expand any data input point
Multiplex dual data buses
Generate four functions of two variables (one variable is common)
Source programmable counters

16 pin DIP. Manufactured by Fairchild.
