Quadruple 1-of-2 Data Selectors/Multiplexers With 3-State Outputs

The CY74FCT257T 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 at the output is noninverted.
The CY74FCT257T is a Logic implementation of a four-pole, two-position Switch where the position of the Switch is determined by the Logic levels at S. Outputs are in the high-impedance state when the output-enable (OE) input is high.
All but one device must be in the high-impedance state to avoid currents exceeding the maximum ratings if outputs are tied together. OE inputs must ensure that there is no overlap when outputs of 3-state devices are tied together.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
