HV582GA-G

Shift Registers Overview

The HV582GA-G is a unipolar, 96-channel low-voltage serial to high-voltage parallel converter with push-pull outputs. It features six parallel 16-bit shift registers and a 96-bit latch. The device operates at a data clock frequency of 30 MHz, enabling an effective data rate of 180 MHz due to the parallel arrangement. High-voltage supply (VPP) ranges from 10 V to 80 V, supporting up to 75 mA peak output sink/source current. Logic supply voltage (VDD) is 4.5 V to 5.5 V. It is housed in a 169-ball TFBGA package measuring 10 x 10 x 1.1 mm.

Shift Registers Feature Summary

• Provides 96 high-voltage channels with push-pull output capability for simultaneous sourcing and sinking.
• Utilizes six parallel 16-bit shift registers to achieve high-speed data updating rates.
• Supports bidirectional data shifting via a dedicated direction control pin.
• Includes comprehensive control pins for output enable, polarity inversion, and global state setting.

Shift Registers Applications

• Inkjet printer drivers
• AC plasma display data drivers
• 3D printer drivers

Shift Registers Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or direct factory channels. Confirm RoHS compliance status and check for recent Product Change Notifications (PCN) regarding packaging or material updates. Ensure ESD precautions are strictly followed during handling, as the device is sensitive to electrostatic discharge. Validate that the specific ordering suffix matches the required TFBGA package configuration.

Shift Registers Selection Notes

Select this component when designing systems requiring multiple high-voltage outputs with significant current drive capabilities. It is suitable for applications needing fast parallel data conversion from serial inputs. Consider the 169-ball TFBGA package constraints for PCB layout. Evaluate thermal management requirements given the operating junction temperature range and power dissipation characteristics under maximum load conditions.

Shift Registers Part Context

The HV582GA-G belongs to Microchip's HV58x family of serial-to-parallel logic converters. It is functionally related to the HV583, which offers 128 channels. Unlike some lower-channel variants, this part integrates six independent shift registers for enhanced throughput. It serves as a bridge between low-voltage digital logic and high-voltage actuator or display loads.

Shift Registers Replacement Considerations

HV583: Offers 128 channels instead of 96; verify pin compatibility and channel count requirements.

Shift Registers FAQ

How does the DIR pin affect data flow?

The DIR pin controls the direction of input data flow for the shift registers. When set High, data flows counter-clockwise (DnB to DnA); when Low, it flows clockwise (DnA to DnB).

What is the purpose of the OL and OH pins?

The Output Low (OL) pin forces all high-voltage outputs to a Low-level state (HVGND), while the Output High (OH) pin forces them to a High-level state (VPP), overriding stored latch data when OE is active.
