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 low level.
A high level on the Output Enable pin switches the outputs into the high-impedance state.
