IN74AC258 Datasheet (IK Semiconductor) - Quad 2-1 Data Selector/Multiplexer

IN74AC258, Quad 2-1 Data Selector/Multiplexer

TECHNICAL DATA IN74AC258 Quad 2-Input Data Selector/Multiplexer with 3-State Outputs High-Speed Silicon-Gate CMOS The IN74AC258 is identical in pinout to the LS/ALS258, HC/HCT258.

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 inverted from when the Output Enable pin is at a
