HV5308PG-B-G

Shift Registers Overview

The HV5308PG-B-G is a low voltage serial to high voltage parallel converter manufactured by Microchip Technology, originally designed by Supertex. It features a 44-lead PQFP package and utilizes HVCMOS technology for efficient level shifting. The device includes a 32-bit shift register, 32 latches, and push-pull output buffers capable of sourcing and sinking current. It operates with a logic supply voltage (VDD) range of 10.8V to 13.2V and supports a high voltage supply (VPP) up to 80V. The shift register speed reaches 8.0MHz, and it provides forward and reverse shifting options.

Shift Registers Feature Summary

• Processes data using HVCMOS technology for low power level shifting.
• Features latched data outputs with push-pull capability for driving loads.
• Supports both forward and reverse shifting directions within the register.
• Includes a diode connection to VPP to allow 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 that the ordering suffix 'G' confirms RoHS compliance as indicated in the datasheet. Confirm the package type corresponds to the 44-Lead PQFP variant specified for the PG suffix. Ensure the component source matches the original Supertex specifications now managed under Microchip Technology. Check for any specific Hi-Rel process flow requirements if applicable to the intended application environment.

Shift Registers Selection Notes

Select this component when a serial-to-parallel conversion with high voltage push-pull outputs is required. It is suitable for applications needing multiple output channels with significant current sourcing and sinking capabilities. Consider the 44-lead PQFP package constraints and the specific voltage requirements for VDD and VPP rails during system design.

Shift Registers Part Context

This part belongs to the HV5308B series, which are low voltage serial to high voltage parallel converters. The series is designed primarily for driving display technologies such as AC-EL and plasma panels. The HV5308B integrates a 32-bit shift register and latches to manage data transfer efficiently.

Shift Registers Replacement Considerations

The HV5308PJ-B-G is a pin-compatible alternative available in a 44-lead PLCC package. Both devices share the same core functionality and electrical characteristics but differ in physical package dimensions and mounting style.

Shift Registers FAQ

How does the latch enable (LE) input affect data transfer?

When the LE input is high, data from the shift register is transferred into the data latches. When LE is low, the data remains latched, allowing new data to be clocked into the shift register without affecting the outputs.

What is the function 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 HV5308B devices.
