IN74AC257, Quad 2-Input Date Selector/Multiplexer with 3-State Outputs High-Speed Silicon-Gate CMOS

TECHNICAL DATA IN74AC257 Quad 2-Input Data Selector/Multiplexer with 3-State Outputs High-Speed Silicon-Gate CMOS The IN74AC257 is identical in pinout to the LS/ALS257, HC/HCT257.

The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.

This device selects a (4-bit) nibble from either the A or B inputs as determined by the Select input.

The nibble is presented at the outputs in noninverted from when the Output Enable pin is at
