74LVX161284A  
Low Voltage IEEE 161284 Translating Transceiver  
General Description  
Features  
The LVX161284A contains eight bidirectional data buffers  
■ Supports IEEE 1284 Level 1 and Level 2 signaling  
standards for bidirectional parallel communications  
between personal computers and printing peripherals  
with the exception of output slew rate  
and eleven control/status buffers to implement  
a full  
IEEE 1284 compliant interface. The device supports the  
IEEE 1284 standard, with the exception of output slew rate,  
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).  
■ Translation capability allows outputs on the cable side to  
interface with 5V signals  
■ All inputs have hysteresis to provide noise margin  
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 (VCC cable) to allow these out-  
■ B and Y output resistance optimized to drive external  
cable  
■ B and Y outputs in high impedance mode during power  
down  
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 VCC cable supply to provide proper  
■ Inputs and outputs on cable side have internal pull-up  
resistors  
■ Flow-through pin configuration allows easy interface  
between the “Peripheral and Host”  
termination and pull-ups for open drain mode.  
■ Replaces the function of two (2) 74ACT1284 devices  
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–B8 transceiver  
pins.
