74LVX161284 Low Voltage IEEE 161284 Translating Transceiver

January 1999

Revised June 2005

74LVX161284

Low Voltage IEEE 161284 Translating Transceiver

General Description

The LVX161284 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 an

Extended Capabilities Port mode (ECP). The pinout allows

for easy connection from the Peripheral (A-side) to the

Host (cable side).

Outputs on the cable side can be configured to be either

open drain or high drive (

14 mA) and are connected to a

separate power supply pin (V

-cable) to allow these out-

puts to be driven by a higher supply voltage than the A-

side. The pull-up and pull-down series termination resis-

tance of these outputs on the cable side is optimized to

drive an external cable. In addition, all inputs (except HLH)

and outputs on the cable side contain internal pull-up resis-

tors connected to the V

-cable supply to provide proper

termination and pull-ups for open drain mode.

Outputs on the Peripheral side are standard low-drive

CMOS outputs designed to interface with 3V logic. The DIR

input controls data flow on the A

–A

–B

transceiver

pins.

Features

Supports IEEE 1284 Level 1 and Level 2 signaling

standards for bidirectional parallel communications

between personal computers and printing peripherals

Translation capability allows outputs on the cable side to

interface with 5V signals

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”
