HV57009PG-G

Shift Registers Overview

The HV57009PG-G is a 64-channel serial-to-parallel converter with P-channel open-drain outputs, designed for plasma panel driving. It features two parallel 32-bit shift registers allowing up to 8 MHz clock frequency per register (16 MHz equivalent data rate). The device operates on a 4.5 V to 5.5 V logic supply and supports output voltages down to -85 V. Output current is adjustable from 0.1 mA to 2 mA via an external resistor or current source. It includes latched data outputs, forward/reverse shifting options, and blanking control.

Shift Registers Feature Summary

• Features dual 32-bit shift registers enabling high-speed data processing at double the speed of single registers.
• Provides 64 channels of constant-current sourcing capability with programmable limits controlled by external components.
• Supports bidirectional data shifting through a dedicated direction pin for flexible cascading and configuration.

Shift Registers Procurement Notes

Verify the component matches the specific datasheet revision DS20005856A. Confirm the package type is 80-lead PQFP and that the suffix indicates lead-free/RoHS compliance. Ensure the ordering quantity aligns with the standard tray packaging of 66 units per tray as specified in the product identification system.

Shift Registers Selection Notes

Select this component when designing systems requiring high-voltage output control with precise current regulation. It is suitable for applications needing serial input expansion to parallel high-voltage outputs. Consider the thermal resistance of the 80-lead PQFP package and ensure adequate heat dissipation if operating near maximum power dissipation limits.

Shift Registers Part Context

This part belongs to Microchip's high-voltage driver family, specifically engineered for low-voltage to high-voltage conversion. It integrates control logic for output blanking and latching, distinguishing it from standard logic converters by its ability to drive loads directly with regulated current sources.

Shift Registers FAQ

How is the output current controlled?

The output current is adjustable from 0.1 mA to 2 mA using one external resistor or a current source connected to the reference pins.

What determines the data shifting direction?

The DIR pin controls the shifting direction; connecting it to VDD enables clockwise shifting, while connecting it to VSS enables counter-clockwise shifting.
