描述
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 device operates at -40 °C to +85 °C.
