Description

The 74F657 is an octal transceiver featuring non–inverting buffers with 3–state outputs and an 8–bit parity generator/checker, and is intended for bus–oriented applications. The buffers have a guaranteed current sinking capability of 24mA at the A ports and 64mA at the B ports.

Key Features

  • bines 74F245 and 74F280A functions in one package
  • High impedance base input for reduced loading (70µA in high and low states)
  • Ideal in applications where high output drive and light bus loading are required (IIL is 70µA vs FAST std of 600µA)
  • Input diodes for termination effects
  • 24–pin plastic slim DIP (300mil) package
  • Industrial temperature range available (–40°C to +85°C)
