HV5622PJ-G

Shift Registers Overview

The HV5622PJ-G is a low-voltage serial-to-high-voltage parallel converter manufactured by Microchip Technology. It features 32 open-drain outputs designed for driving AC-electroluminescent displays and other high-voltage current-sinking applications. The device operates with a logic supply voltage (VDD) ranging from 10.8 V to 13.2 V and supports high-voltage output levels up to +220 V. It incorporates a 32-bit shift register, latches, and control logic for polarity selection and blanking. The component utilizes CMOS-compatible inputs and supports clock frequencies up to 8 MHz.

Shift Registers Procurement Notes

Verify the specific package type matches the required PCB footprint, as the PJ suffix indicates a 44-lead PLCC package. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix aligns with the desired media type and environmental specifications provided in the product identification system. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations before finalizing procurement.

Shift Registers Selection Notes

Select this component when an application requires multiple-output high-voltage current-sinking capabilities driven by low-voltage logic signals. The device is suitable for designs needing precise control over output polarity and blanking states. Consider the operating temperature range of -40°C to +85°C for environmental compatibility. Evaluate the maximum sink current and voltage ratings against the load requirements to ensure reliable operation within the recommended operating conditions specified in the datasheet.

Shift Registers Part Context

The HV5622PJ-G belongs to the HV5622 family of serial-to-parallel converters produced by Microchip Technology. This series is engineered specifically for driving display technologies that require high-voltage outputs controlled by standard logic interfaces. The PJ variant denotes the 44-lead Plastic Leaded Chip Carrier package, distinguishing it from the PQFP option. These devices are integral components in driver circuits for specialized display and printing systems.

Shift Registers Replacement Considerations

HV5622PG-G: Identical functional specifications but housed in a 44-lead PQFP package instead of PLCC.
