KK74LS157

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 as the LS257 but the latter is provided with 3-state

outputs.
