HV583

128-Channel Serial to Parallel Converter

with Push-Pull Outputs

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.

High at RST input pin clears contents of both: the shift register

and the latch. The outputs can be in a high impedance state via

the output enable logic pin.
