HV9708PJ-G

Shift Registers Overview

The HV9708PJ-G is a 32-channel serial-to-parallel converter manufactured by Microchip Technology, originally designed by Supertex Inc. It utilizes HVCMOS technology to provide high-voltage push-pull outputs capable of driving loads up to 80V. The device features a 32-bit shift register and latched data outputs, with logic inputs compatible with 5.0V CMOS standards. It operates within a supply voltage range of 4.5V to 5.5V for VDD and 8.0V to 80V for VPP. The component supports clock frequencies up to 8.0MHz and functions reliably in temperatures ranging from -40°C to +85°C.

Shift Registers Feature Summary

• Provides 32 high-voltage push-pull outputs driven by an internal 32-bit shift register and latch structure.
• Supports forward and reverse shifting options with cascading capability via a dedicated data output pin.
• Features low power level shifting with fully CMOS-compatible logic inputs for easy interface integration.
• Includes polarity select and blanking control logic to manage output states efficiently.

Shift Registers Applications

• Driver for AC-electroluminescent displays
• Driving plasma panels requiring multiple high-voltage current sourcing and sinking capabilities
• Vacuum fluorescent display systems
• Large matrix LCD displays

Shift Registers Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number HV9708PJ-G corresponds to tube packaging, while the suffix M903 indicates reel packaging. Confirm RoHS compliance status as indicated by the -G designation. Ensure the source document matches the required package type and packing quantity for your assembly process.

Shift Registers Selection Notes

Select this component for applications requiring direct drive of high-voltage loads without external transistor arrays. It is suitable where space constraints favor a single IC solution over discrete components. Consider the 44-lead PLCC package availability and thermal resistance characteristics during PCB layout planning. Verify that the system's logic levels align with the specified 5.0V CMOS input requirements.

Shift Registers Part Context

This device belongs to the HV9708 family of high-voltage serial-to-parallel converters. Originally developed by Supertex Inc., the product line was acquired by Microchip Technology. The HV9708 series is distinct from other logic families due to its specialized HVCMOS process, designed specifically for high-voltage display driving applications rather than general-purpose logic conversion.
