RANSCEIVER
High-Speed Silicon-Gate CMOS
The IN74ACT620 is identical in pinout to the LS/ALS620,
HC/HCT620. The IN74ACT620 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS
inputs.
The IN74ACT620 is a 3-state transceiver that is used for 2-
way communication between data buses. Two separate enables
are available. The enable for bus A to B is active-high, the
enable for bus B to A is active-low.
