74F657 - Octal Transceiver

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.

Features

  • Combines 74F245 and 74F280A functions in one package.
  • High impedance base input for reduced loading (70µA in high and low states).
  • Ideal in.
