General Description

The Supertex HV583 is a 128 channel low voltage serial to high

voltage parallel converter with push-pull outputs. This device

has been designed for use as a display driver. It can also be used

in any application requiring multiple output, high voltage current

sourcing and sinking capability such as plasma displays and

inkjet printers. The device has 4 parallel 32-bit shift registers,

permitting data rates 4X the speed of one. The data are shifted

in during the low to high clock transition. There are also 128

latches and control logic to shift clockwise or counterclockwise.

The outputs can be in a high impedance state via the output

enable logic pin.
