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 DM74LS157 presents true data where as the DM74LS158 presents inverted data to minimize propagation delay time.
Features
■ Buffered inputs and outputs
■ Typical Propagation Time
DM74LS157 9 ns
DM74LS158 7 ns
■ Typical Power Dissipation
DM74LS157 49 mW
DM74LS158 24 mW
Applications
? Expand any data input point
? Multiplex dual data buses
? Generate four functions of two variables (one variable is common)
? Source programmable counters
