Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename
Nexperia.
Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use

PDI1284P11
3.3 V parallel interface transceiver/buffer
Rev. 03 — 25 August 2008
Product data sheet
1. General description
The PDI1284P11 parallel interface chip is designed to provide an asynchronous, 8-bit,
bidirectional, parallel interface for personal computers. The PDI1284P11 includes all 19
signal lines defined by the IEEE 1284 interface specification for Byte, Nibble, EPP, and
ECP modes. The PDI1284P11 is designed for hosts or peripherals operating at 3.3 V to
interface 3.3 V or 5.0 V devices.
The eight transceiver pairs (A/B 1 to 8) allow data transmission from the A-bus to the
B-bus, or from the B-bus to the A-bus, depending on the state of the direction pin DIR.
The B-bus and the Y9 to Y13 lines have either totem pole or resistor pull-up outputs,
depending on the state of the high drive enable pin HD. The A-bus has only totem pole
style outputs. All inputs are TTL compatible with at least 400 mV of input hysteresis at
V
CC
= 3.3 V.
