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.

• Buffered Inputs and Outputs
• Common Strobe/Select input for all 4 circuits
