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.
The outputs can be in a high impedance state via the output
enable logic pin.
