IEEE 1284收发器 IEEE 1284 Transceiver

General Description

The VHC161284 contains eight bidirectional data buffers and eleven control/status buffers to implement a full IEEE 1284 compliant interface. The device supports the IEEE 1284 standard and is intended to be used in Extended Capabilities Port mode ECP. The pinout allows for easy connection from the Peripheral A-side to the Host cable side.

Features

■Supports IEEE 1284 Level 1 and Level 2 signaling standards for bidirectional parallel communications between personal computers and printing peripherals

■Replaces the function of two 2 74ACT1284 devices

■All inputs have hysteresis to provide noise margin

■B and Y output resistance optimized to drive external cable

■B and Y outputs in high impedance mode during power down

■Inputs and outputs on cable side have internal pull-up resistors

■Flow-through pin configuration allows easy interface between the Peripheral and Host
