OCTAL 3-STATE INVERTING BUS TRANSCEIVER
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.
