CY74FCT2257ATQCT from Texas Instruments is a Integrated Circuit Quadruple 1-of-2 Data Selectors/Multiplexers with 3-State Outputs and Series Damping Resistors - Digital multiplexers & encoders. 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 I 0 inputs are selected when S is low, and the I 1 inputs are selected when S is high. Data appears at the output in noninverted form for the CY74FCT2257T. On-chip termination resistors at the outputs reduce system noise caused by reflections. The CY74FCT2257T can replace the FCT257T to reduce noise in an existing design. The CY74FCT2257T is a logic implementation of a four-pole, two-position switch, in which the position of the switch is determined by the logic levels supplied to S. Outputs are forced to the high-impedance off state when the output-enable (OE) input is high. All but one device must be in the high-impedance state to prevent currents from exceeding the maximum ratings if outputs are tied together. Design of the OE signals 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 I off. The I off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
