HV5222PJ-G

Shift Registers Overview

The HV5222PJ-G is a 32-channel serial-to-parallel logic converter manufactured by Microchip Technology. It utilizes High Voltage CMOS technology and features open-drain outputs capable of sinking a minimum of 100mA. The device operates with a logic supply voltage (VDD) ranging from 10.8V to 13.2V, typically at 12V, while high-voltage outputs support up to 225V using a ramped supply. It includes a 32-bit static shift register, data output for cascading, and control inputs for strobe and enable functions. The component is housed in a 44-lead PLCC package and supports clock frequencies up to 8.0MHz.

Shift Registers Feature Summary

• High-voltage capability with open-drain outputs supporting up to 225V via a ramped supply
• Integrated 32-bit static shift register with forward shifting direction
• Cascading capability through a dedicated data output buffer reflecting the last bit status
• CMOS-compatible low-voltage logic inputs with defined Output Enable and Strobe controls

Shift Registers Applications

• Driver for AC electroluminescent displays
• Inkjet and electrostatic print head drivers
• Plasma panel driving circuits
• Vacuum fluorescent display systems
• Large matrix LCD display drivers

Shift Registers Procurement Notes

Verify that the specific ordering suffix PJ-G corresponds to the 44-lead PLCC package configuration and lead-free/ROHS-compliant status as documented in the manufacturer's product identification system. Confirm that the application design accommodates the recommended operating conditions, specifically the VDD range of 10.8V to 13.2V and the high-voltage output limits. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Shift Registers Selection Notes

Select the HV5222PJ-G when a clockwise data shift direction is required for the 32-bit serial-to-parallel conversion process. This model is distinct from the HV5122 variant, which shifts data in a counter-clockwise direction. Consider this component for applications requiring multiple high-voltage current-sinking outputs within a single integrated circuit solution. Verify compatibility with the system's logic voltage levels and clock frequency requirements before integration.

Shift Registers Part Context

This component belongs to the HV5122/HV5222 family of low-voltage serial to high-voltage parallel converters designed primarily for display and print head applications. The family shares identical electrical characteristics and functional block diagrams, differing only in the internal shift register data flow direction and the specific package type selected. The PJ designation indicates the Plastic Leadless Chip Carrier form factor.

Shift Registers Replacement Considerations

The HV5122PJ-G serves as a functional substitute if the system architecture supports counter-clockwise data shifting instead of the clockwise direction inherent to the HV5222 series. Both devices share the same pinout, package dimensions, and electrical specifications.

Shift Registers FAQ

How does the data shift direction differ between the HV5122 and HV5222 models?

The HV5222 shifts data in the clockwise direction when viewed from the top of the package, whereas the HV5122 shifts data in the counter-clockwise direction.

What is the function of the Data Out pin on the HV5222PJ-G?

The Data Out pin provides a buffer that reflects the current status of the last bit of the shift register, allowing for cascading to the data input of subsequent devices without affecting the internal shift register operation.

How do the OE and STR inputs affect the shift register operation?

The Operation Enable (OE) and Strobe (STR) inputs control the state of the high-voltage outputs but do not affect the operation of the shift register itself. Data continues to be shifted into the register regardless of these control states.
