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).
The HV583 is a low‑voltage serial to high‑voltage parallel converter designed for display drivers, plasma displays and ink‑jet printers. It contains four 32‑bit shift registers, providing data rates four times faster than a single register, and offers forward and reverse shifting via the DIR pin.
Key features include 128 channels, 5 V CMOS logic, output voltages up to 80 V, +30 mA output current capability, 40 MHz clock frequency, hot‑switchable push‑pull outputs, and low‑power level shifting. Absolute maximum ratings, operating conditions, and detailed pin descriptions are provided for design integration.
