74F621 Octal Bus Transceiver

The 74F621 is an octal transceiver featuring non-inverting open collector bus-compatible outputs in both send and receive directions. The outputs are capable of sinking 64mA, providing very good capacitive drive characteristics. This octal bus transceiver is designed for asynchronous two-way communi.
