CY74FCT2257T - QUAD 2-INPUT MULTIPLEXER
The CY74FCT2257T has four identical two-input multiplexers that select four bits of data from two sources under the control of a common data-select (S) input.
The I0 inputs are selected when S is low, and the I1 inputs are selected when S is high.
Data appears at the output in noninverted form for t
