The HV633 is a 32-channel driver IC for gray shade display use. It is designed to produce varying output voltages between 3.0 - 80V. This amplitude modulation at the output is facilitated by an external ramp voltage VR. See Theory of Operation for detailed explanation.This device consists of dual 16-bit shift registers, 32 data latches and comparators, and control logic to preform 128 levels of gray shading. There are 7 bits of data inputs. Data is shifted through the shift registers at both edges of the clock, resulting in a data transfer rate of twice that of the shift clock frequency. When the DIR pin is high, CSI/CSO is the input/output for the chip select pulse. When DIR is low, CSI/CSO is the output/input for the chip select pulse. When the DIR pin is high, it allows the HV633 to shift data in the counter-clockwise direction when viewed from the top of the package. When the DIR pin is low, data is shifted in the clockwise direction. The output circuitry allows the energy which is stored in the output capacitance to be returned to VPP through the body diode of the outputtransistor.
