HV7022PJ-C-G

Shift Registers Overview

The HV7022PJ-C-G is a low-voltage serial to high-voltage parallel converter with push-pull outputs, manufactured by Supertex Inc. It features 34 output lines and utilizes HVCMOS technology for symmetric row drive in ACTFEL displays. The device operates with a logic supply voltage (VDD) ranging from 10.8 V to 13.2 V and supports a high-voltage supply (VPP) up to 230 V. It includes a direction pin for shift register loading control, output enable functionality, and polarity control. The maximum clock frequency is 4.0 MHz, and it is housed in a 44-lead PLCC package.

Shift Registers Feature Summary

• Symmetric row drive capability designed to reduce latent imaging in ACTFEL displays
• Push-pull outputs capable of sourcing or sinking a minimum of 70 mA
• Pin-programmable shift direction allowing CW or CCW shift register loading
• Low power level shifting integrated within the CMOS architecture

Shift Registers Applications

• ACTFEL display row drivers
• High-voltage parallel conversion systems
• AC thin-film electroluminescent display controllers

Shift Registers Procurement Notes

Verify that the ordering suffix 'G' confirms RoHS compliance as indicated in the datasheet. Confirm the package type matches the 44-lead PLCC specification. Ensure the manufacturer designation aligns with Supertex Inc., noting potential acquisition history. Check for any specific environmental or reliability certifications required for the application environment.

Shift Registers Selection Notes

Select this component when a high-voltage parallel output interface is required for AC thin-film electroluminescent displays. The device is suitable for applications needing symmetric row driving to minimize image retention. Consider the 4.0 MHz clock speed and 34-channel capacity against system timing requirements. Verify that the operating temperature range meets the environmental conditions of the target assembly.

Shift Registers Part Context

This part belongs to the HV7022 series of high-voltage logic converters originally developed by Supertex Inc. The series is engineered for driving electroluminescent panels. The PJ suffix denotes the plastic leaded chip carrier package variant. The C suffix indicates the commercial temperature grade. The G suffix specifies green/RoHS-compliant packaging.

Shift Registers Replacement Considerations

Check for direct equivalents within the HV7022 family, such as the HV7022DJ-C for ceramic packages. Verify pin compatibility and electrical characteristics before substituting with other high-voltage shift registers. Consult the manufacturer for updated product line information regarding discontinued components.
