7HCT1284D - Parallel printer interface transceiver/buffer

General Description

The 74HCT1284 parallel interface chip is designed to provide an asynchronous, 4-bit, bi-directional, parallel printer interface for personal computers.

Three additional lines are included to provide handshaking signals between the host and the peripheral.

Key Features

  • Asynchronous operation.
  • 4-Bit transceivers.
  • 3 additional buffer/driver lines.
  • TTL compatible inputs.
  • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model.
