CY74FCT2257AT 具有三态输出和串联阻尼电阻的四路 2 选 1 数据选择器/多路复用器

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 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

The \x92FCT157T devices are logic implementations of a four-pole, two-position switch, where the position of the switch is determined by the logic levels at S
