General Description
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
