  • 74F640 Octal Bus Transceiver Inverting (3-State) IC (74640) DIP-20 Package

The 74F640 is an octal transceiver featuring inverting 3-State bus compatible outputs in both transmit and receive directions. The B port outputs are capable of sinking 64mA and sourcing 15mA, providing very good capacitive drive characteristics. The device features an Output Enable (OE) input for easy cascading and Transmit/Receiver (T/R) input for direction control. The 3-State outputs, B0–B7, have been designed to prevent output bus loading if the power is removed from the device

Features :-

  • High-impedance NPN base inputs for reduced loading (70µA in High and Low states)
  • Ideal for applications which require high-output drive and minimal bus loading
  • Inverting version of 74F245
  • Octal bidirectional bus interface
  • 3-State outputs sink 64mA and source 15mA

Specifications :-

  • Supply voltage : 4.5V - 5.5V
  • High-level input voltage : 2.0V
  • Low-level input voltage : 0.8V
  • Input clamp current : -18mA
  • High-level output current : -3mA
  • Low-level output current : 24mA
  • Operating free-air temperature : 70°C

Package Includes :-

1 X 74F640 Octal Bus Transceiver Inverting (3-State) IC (74623) DIP-20 Package
