HV5222PG-G

Shift Registers Overview

The HV5222PG-G is a 32-channel serial-to-parallel logic converter manufactured by Microchip Technology. It utilizes High Voltage CMOS technology to provide open-drain outputs capable of sinking a minimum of 100mA with output voltages up to 225V using a ramped supply voltage. The device operates on a low-voltage logic rail (VDD) ranging from 10.8V to 13.2V, typically at 12V, while the high-voltage supply (VPP) supports up to 250V. It features an 8.0MHz shift register speed and includes strobe and enable inputs for control. Data shifts in a clockwise direction when viewed from the top of the package.

Shift Registers Feature Summary

• High voltage capability with open-drain outputs supporting up to 225V via ramped supply
• Integrated 32-bit static shift register with forward shifting capability
• CMOS compatible inputs allowing direct interface with standard logic levels
• Data output buffer provided for cascading multiple devices

Shift Registers Applications

• Driver for AC electroluminescent displays
• Driving inkjet and electrostatic print heads
• Plasma panel control
• Vacuum fluorescent display driving
• Large matrix LCD display driving

Shift Registers Procurement Notes

Verify that the ordering suffix 'PG' corresponds to the 44-Lead PQFP package as specified in the datasheet. Confirm the 'G' suffix indicates a lead-free/ROHS-compliant package. Ensure the system design limits current through each output or switches off the high voltage supply before changing output states, as required by the device specifications.

Shift Registers Selection Notes

Select the HV5222PG-G over the HV5122 variant when data must shift in a clockwise direction relative to the package orientation. This component is suitable for applications requiring multiple high-voltage current-sinking outputs. Ensure the application environment stays within the -40°C to +85°C operating temperature range and respects the absolute maximum ratings for VDD and VPP.

Shift Registers Part Context

This part belongs to the HV5122/HV5222 family of low-voltage serial to high-voltage parallel converters. While functionally identical regarding electrical characteristics, the HV5222 differs from the HV5122 specifically in its internal data shift direction. Both share the same pinout structure and are designed for similar high-voltage display and printing applications.

Shift Registers Replacement Considerations

The HV5122PG-G is a functional substitute if the specific clockwise data shift direction of the HV5222 is not critical to the system design. Both parts share identical electrical specifications and pinouts.
