Description

The KK74AC258 is identical in pinout to the LS/ALS258, HC/HCT258. The device inputs are compatible with standard MOS 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  resented at the outputs in inverted from when the Output Enable pin is at a low level. A high level on the Output  nable pin switches the outputs into the high-impedance state.
