DESCRIPTION
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 communication between data buses. The control function implementation allows for maximum flexibility in timing.

FEATURES
• High-impedance NPN base inputs for reduced loading (20µA in High and Low states)
• Octal bidirectional bus interface
• Open collector outputs sink 64mA
• Non-inverting
