HV5408PJ-B-G

Shift Registers Overview

The HV5408PJ-B-G is a low voltage serial to high voltage parallel converter manufactured by Microchip Technology (originally Supertex). It features a 32-bit shift register, 32 latches, and push-pull outputs. The device operates with a logic supply voltage of 10.8V to 13.2V and a high voltage supply range of 8.0V to 80V. It supports clock frequencies up to 8.0MHz and provides source/sink currents of at least 20mA. The component is housed in a 44-lead PLCC package and functions within an operating temperature range of -40°C to +85°C.

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 to confirm the package type and compliance status. The 'PJ' designation indicates a 44-lead PLCC package. The '-G' suffix confirms RoHS compliance. Ensure the procurement documentation matches the original manufacturer specifications from Supertex or current authorized distributors to guarantee authenticity and correct pinout configuration.

Shift Registers Selection Notes

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

Shift Registers Part Context

This part belongs to the HV5408B series, which includes variants like HV5408DJ-B and HV5408PG-B. These devices are designed as low voltage serial to high voltage parallel converters. The series is characterized by its ability to drive various display technologies requiring high voltage push-pull outputs.

Shift Registers Replacement Considerations

HV5408PJ-G is a direct equivalent variant within the same series offering the same 44-lead PLCC package form factor.

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 HV5408B devices.
