    Short Description

    Quad 2-Line to 1-Line Data Selectors/Multiplexers.

    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.
