description
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.

● Function, Pinout, and Drive Compatible With FCT and F Logic
● Reduced VOH (Typically = 3.3 V) Version of Equivalent FCT Functions
● Edge-Rate Control Circuitry for Significantly Improved Noise Characteristics
● Ioff Supports Partial-Power-Down Mode Operation
● Matched Rise and Fall Times
● Fully Compatible With TTL Input and Output Logic Levels
● ESD Protection Exceeds JESD 22
    − 2000-V Human-Body Model (A114-A)
