HV583 DEVICE OVERVIEW
The HV583 is a unipolar 128-channel, low-voltage serial to high-voltage parallel
converter with push-pull outputs, dedicated to printer driver and plasma display
applications. The device has been designed for applications that require high channel
count and high output voltage swing (0-80V) with current sinking and sourcing
capabilities of 30 mA.
The device consists of four parallel 32-bit Shift registers, a 128-bit latch and
128 high-voltage outputs. The 32-bit Shift registers can operate up to a 40 MHz speed
rate, allowing for fast data update. The parallel arrangement of the registers permits
four times the speed of a single register, providing a fast update rate for the 128 output
channels. Data flow can be shifted from a clockwise to a counterclockwise direction via
the DIR pin. All high-voltage outputs can be forced to a low-level, high-level or
high-impedance state (high Z) through the OL, OH and OE pins, respectively.

EVALUATION BOARD OVERVIEW
The HV583 128-Channel High-Voltage Driver IC Evaluation Board facilitates the quick
implementation for display and printer driver applications with its flexible input/output
connection interface.
The evaluation board is designed to be operated together with the Microchip
Technology PIC32 Starter Kit (DM320001) or with a generic signal pattern generator via
the dedicated J5 pin header connector (see
).
There are 32 test point pads corresponding to the first 32-bit register (D1A/D1B) that
control the high-voltage outputs: HV
OUT
0, 4, 8...124. Ground pads are provided along
with the test point pads to facilitate the analysis of the high-voltage output channels.
Refer to
and to the HV583 Data Sheet.
All output channels are available via a 160-position, high-density array female
connector, where only 128 positions are used (refer to the
in
Appendix A. “Schematic and Layouts”
for more details).
