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 (
r 14 mA) and are connected to a
separate power supply pin (VCC-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 VCC-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 A1–A8/B1–B8 transceiver
pins.
Features
s Supports IEEE 1284 Level 1 and Level 2 signaling
standards for bidirectional parallel communications
between personal computers and printing peripherals
s Translation capability allows outputs on the cable side to
interface with 5V signals
s All inputs have hysteresis to provide noise margin
s B and Y output resistance optimized to drive external
cable
s B and Y outputs in high impedance mode during power
down
s Inputs and outputs on cable side have internal pull-up
resistors
s Flow-through pin configuration allows easy interface
between the “Peripheral and Host”
s Replaces the function of two (2) 74ACT1284 devices
Ordering Code
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
