FUNCTIONAL DESCRIPTION

The HV583 is a unipolar, 128-channel low-voltage

serial to high-voltage parallel converter. The device

consists of four parallel 32-bit shift registers, a 128-bit

latch and 128 high-voltage outputs.

The four independent shift registers allow data to be

updated into the 128-bit latch at four times the speed of

a single register, providing a fast update rate for the

128 output channels. The 128-bit latch holds the data

for the high-voltage output channels; whether it is a

High-level or Low-level state. The flow of the input data

can switch direction from clockwise (DnB to DnA) to

counter-clockwise (DnA to DnB) by controlling the DIR

pin. A reset pin (RST) is provided to clear the contents

of the latches. All channels can be set at the same time

to a high-impedance state (High Z), Low-level state, or

High-level state through the OE, OL and OH pins,

respectively.

The high-output voltages (HVOUTn) can operate from

15V to 80V with a maximum current source and sink

capability of 30 mA.

Application Information

HV583 is designed for applications requiring multiple

high-voltage outputs with current sinking and sourcing

capabilities in the range of

±30 mA.

Typical

applications where the HV583 is utilized are in plasma

displays, Inkjet printer drivers and 3D printer drivers.
