SL74LS157 Quad 2-Input Data Selector/Multiplexer This monolitic data selector/multiplexer contains 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 has the same functions and pin connections.
