General Description
These devices are octal bus transceivers designed for asynchronous two-way data flow between the A and B busses. Both busses are capable of sinking 64 mA and have 3- STATE outputs. Dual enable pins (GAB, GBA) allow data transmission from the A bus to the B bus or from the B bus to the A bus. The 74F620 is an inverting option of the 74F623.
