Dual 4-to-1-line Data Selectors/Multiplexers
Description
Information on the data inputs of each multiplexer is selected by the address on the A and B inputs, and is
presented on the Y outputs. Each multiplexer possesses a strobe input which enables it when taken to a low
logic level. When a high logic level is applied to a strobe input, the output of its associated multiplexer is
taken low.
