HV5308PJ-B-G

Shift Registers Overview

The HV5308PJ-B-G is a low voltage serial to high voltage parallel converter with push-pull outputs, manufactured by Microchip Technology. It features a 32-bit shift register and 32 latches in a 44-PLCC package. The device operates on a logic supply (VDD) of 10.8V to 13.2V and a high voltage supply (VPP) ranging from 8.0V to 80V. It supports clock frequencies up to 8.0MHz and provides source/sink currents of at least 20mA per output.

Shift Registers Feature Summary

• Processes data using HVCMOS technology for efficient level shifting.
• Provides latched data outputs with CMOS compatible inputs.
• Supports both forward and reverse shifting options.
• Includes a diode connection to VPP for efficient power recovery.

Shift Registers Applications

• Driver for AC-electroluminescent displays
• Driving plasma panels
• Vacuum fluorescent display drivers
• Large matrix LCD displays

Shift Registers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and compliance status. Confirm that the component matches the required RoHS specifications and check for any recent Product Change Notifications regarding assembly sites or design revisions before finalizing procurement.

Shift Registers Selection Notes

Select this component when a serial-to-parallel conversion with high voltage push-pull outputs is required. Ensure the application voltage requirements fall within the specified VDD and VPP ranges. Consider the 44-PLCC package dimensions and pinout compatibility with the target PCB layout during the selection process.

Shift Registers Part Context

This part belongs to the HV5308B series, which includes variants such as HV5308DJ-B and HV5308PG-B. The PJ suffix specifically denotes the 44-Lead Plastic Leadless Chip Carrier (PLCC) package option. The series is designed for applications requiring multiple output high voltage current sourcing and sinking capabilities.

Shift Registers Replacement Considerations

Direct substitutes include other packages within the same family, such as HV5308PG-B-G for the PQFP variant. Verify pinout compatibility and electrical characteristics before substituting with different package types.

Shift Registers FAQ

How does the Latch Enable (LE) input function?

When LE is HIGH, data from the shift register is transferred into the data latch. When LE is LOW, the data remains latched, allowing new data to be clocked into the shift register.

What is the purpose of the DATA OUT pin?

The DATA OUT pin provides a serial data output that reflects the current status of the last bit of the shift register, enabling the cascading of multiple devices.
