DM54LS157 - Quad 2-Line to 1-Line Data Selectors/Multiplexers
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 present

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
