The IN74ACT258 is identical in pinout to the LS/ALS258,
HC/HCT258. The IN74ACT258 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS
inputs.
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.
TTL/NMOS Compatible Input Levels
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 4.5 to 5.5 V
Low Input Current: 1.0
