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 LS157 presents true data whereas the LS158 presents inverted data to minimize propagation delay time.

Features

Buffered inputs and outputs
Typical Propagation Time
LS157 9 ns
LS158 7 ns
Typical Power Dissipation
LS157 49 mW
LS158 24 mW
Alternate Military/Aerospace device (54LS157, 54LS158) is available. Contact a National Semiconductor Sales Office/Distributor for specifications.

Applications

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