The
KK
74AC258 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.
Outputs Directly Interface to CMOS, NMOS, and TTL
