The 74FCT621T is an octal transceiver with non-inverting Open- Drain bus compatible outputs in both send and receive directions. The B bus outputs are capable of sinking 64mA providing very good capacitive drive characteristics. The 74FCT621A is designed for asynchronous two-way communication between data buses. The 74FCT621A operates at -40C to +85C
