74F620 - Octal bus transceiver/inverting

Description

The 74F620 is an octal transceiver featuring inverting 3-State bus-compatible outputs in both send and receive directions.

The outputs are capable of sinking 64mA and sourcing up to 15mA, providing very good capacitive drive characteristics.

The 74F623 is a non-inverting version of the 74F620.

Features

  • 74F620/74F623.
  • High-impedance NPN base inputs for reduced loading (70µA in High and Low states) bus loading Enable inputs (OEBA and OEAB). The Enable inputs can be used to disable the device so that the buses are effectively isolated. The dual-enable configuration gives the 74F620 and 74F623 the capability to store data by the simultaneous enabling of OEBA and OEAB. Each output reinforces its input in this transceiver configuration. Thus, when both control inputs are enabled and all.
