HV633 Supertex inc. 32-Channel, 128-Level Amplitude Gray-Shade Display Column Driver Features General Description HVCMOS technology The HV633 is a 32-channel driver IC for gray shade display use. It is designed to produce varying output voltages between 5.0V CMOS inputs 3.0 - 80V. This amplitude modulation at the output is facilitated Capable of 128 levels of gray shading by an external ramp voltage V . See Theory of Operation for Modulation voltage up to +80V R detailed explanation. 24MHz data throughput rate 32 outputs per device (can be cascaded) This device consists of dual 16-bit shift registers, 32 data Pin-programmable shift direction (DIR) latches and comparators, and control logic to preform 128 D/A conversion cycle time is 20s levels of gray shading. There are 7 bits of data inputs. Data is Diodes in output structure allow usage in energy shifted through the shift registers at both edges of the clock, recovery systems resulting in a data transfer rate of twice that of the shift clock Available in 3-sided 64-lead gull wing package 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 Applications the output/input for the chip select pulse. When the DIR pin is Electroluminescent Displays high, it allows the HV633 to shift data in the counter-clockwise Polycholesteric Displays 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 V through the body diode of PP the output transistor.
