RANSCEIVER
High-Speed Silicon-Gate CMOS
The IN74ACT643 is identical in pinout to the LS/ALS643,
HC/HCT643. The IN74ACT623 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS
inputs.
The IN74ACT643 is a 3-state transceiver that is used for 2-
way asynchronous communication between data buses. The
device has an active-low Output Enable pin, which is used to
place the I/O ports into high-impedance states. The Direction
control determines whether data flows from A to B or from B to A.
