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 high voltage (12V to 40V) or low voltage (0V to 3V).
