74LVXZ161284

Low Voltage IEEE 161284 Translating Transceiver

with Power-Up Protection

General Description

The LVXZ161284 contains eight bidirectional data buffers

Features

I Supports IEEE 1284 Level 1 and Level 2 signaling

standards for bidirectional parallel communications

between personal computers and printing peripherals

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).

I Translation capability allows outputs on the cable side to

interface with 5V signals

I All inputs have hysteresis to provide noise margin

I B and Y output resistance optimized to drive external

cable

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_CC-Cable) that allows these

I B and Y outputs in high impedance mode during power

down

outputs to be driven by a higher supply voltage than

the A-side. The pull-up and pull-down series termination

resistance of these outputs on the cable side is optimized

to drive an external cable. In addition, the C inputs and the

B and Y outputs on the cable side contain internal pull-up

resistors connected to the V_CC-Cablesupply to provide

I C inputs and B, Y outputs on cable side have internal 1.4

kΩ pull-up resistors

I Flow-through pin configuration allows easy interface

between the “Peripheral and Host”

I Replaces the function of two (2) 74ACT1284 devices

proper input termination and pull-ups for open drain output

mode.

I Power-up protection prevents errors when the printer is

powered on but no valid signal is at the input pins

(A₉- A₁₃).

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 A₁–A₈/B₁–B₈transceiver

pins.

This device also has an added power-up protection feature

which forces the Y outputs (Y₉- Y₁₃) to a high state after

power-on until one of the associated inputs (A₉- A₁₃) goes

HIGH. When an associated input (A₉- A₁₃) goes HIGH, all

Y outputs (Y₉- Y₁₃) are activated.
