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 (
separate power supply pin (V
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 V
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 A
pins.
Ordering Code
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
