Shift Registers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and compliance status. Ensure that the procurement channel sources genuine components matching the exact part number designation. Cross-reference the datasheet revision date to confirm technical specifications align with current manufacturing standards before finalizing acquisition.

Shift Registers Selection Notes

Select this component when a serial-to-parallel conversion with high-voltage push-pull output is required. It is suitable for applications needing multiple output channels capable of sourcing and sinking significant current. Consider the 44-lead PLCC package constraints and the specific voltage requirements for both logic and high-voltage rails during circuit design.

Shift Registers Part Context

This part belongs to the HV5308B series of serial to parallel converters. It is designed as a driver for various display technologies requiring high voltage capabilities. The device integrates a static shift register and latch array to manage data flow efficiently. It serves as a bridge between low-voltage control logic and high-voltage display panels.

Shift Registers Replacement Considerations

The HV5308DJ-B and HV5308PG-B-G are alternative package options within the same functional family. Verify pin compatibility and thermal characteristics when substituting these variants. Ensure that the replacement maintains the required 44-lead configuration and electrical performance specifications.

Shift Registers FAQ

How does the Latch Enable (LE) input affect data transfer?

When LE is HIGH, data from the shift register is transferred into the data latches. When LE is LOW, the latched data is retained while new data can be clocked into the shift register.

What is the function of the Output Enable (OE) input?

When OE is LOW, all high voltage outputs are forced into a LOW state regardless of the latched data. When OE is HIGH, the outputs reflect the data stored in the latches.
