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 output transistor.

HV633 is an authentic electronic component manufactured by Microchip, categorized under Integrated Circuits - ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official HV633 datasheet above.
Electronic component spot-market pricing for HV633 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for HV633 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
