74LVXZ161284
Low Voltage IEEE 161284 Translating Transceiver
with Power-Up Protection
General Description
The LVXZ161284 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 (VCC-Cable) that allows these
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 VCC-Cable supply to provide
proper input termination and pull-ups for open drain output
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 A1–A8/B1–B8 transceiver
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.
Features
I Supports IEEE 1284 Level 1 and Level 2 signaling
standards for bidirectional parallel communications
between personal computers and printing peripherals
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
I B and Y outputs in high impedance mode during power
down
I C inputs and B, Y outputs on cable side have internal 1.4
kpull-up resistors
I Flow-through pin configuration allows easy interface
between the “Peripheral and Host”
I Replaces the function of two (2) 74ACT1284 devices
I Power-up protection prevents errors when the printer is
powered on but no valid signal is at the input pins
(A9 - A13).

45 mA VI = VCC or GND
70 mA VI = VCC or GND
Note 6: Power-down leakage to VCC or VCCCable is tested by simultaneously forcing all pins on the cable-side (B1B8, Y9Y13, PLH, C14C17 and HLHIN)
to 5.5V and measuring the resulting ICC or ICCCable.
Note 7: This parameter is guaranteed but not tested, characterized only.
Note 8: Connect all VCC pins and VCC-Cable pins when forcing voltage applied, DIR = HD = 0V.
