Octal 3-State Inverting Bus Transceiver

The IN74AC620 is identical in pinout to the LS/ALS620, HC/HCT620. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. The IN74AC620 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. By Integral Corp.
