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.
