74F621 - Octal Bus Transceiver

General 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.

Key Features

  • High-impedance NPN base inputs for reduced loading (20µA in High and Low states) PIN.
