KR9600-STD

Overview

The KR9600-STD is a keyboard encoder manufactured by SMSC, categorized under signal switches, multiplexers, and decoders. It serves as a direct replacement for the KR3600 component. A key functional distinction is that it eliminates the requirement for a separate negative voltage power input, operating solely on positive supply rails.

Feature Summary

• Functions as a dedicated keyboard encoder within signal processing systems
• Replaces legacy KR3600 units without requiring additional negative voltage infrastructure

Applications

• Direct replacement for KR3600 in existing hardware designs
• Keyboard encoding applications requiring simplified power architectures

Procurement Notes

Verify RoHS compliance status prior to procurement, as documentation indicates non-compliance for this specific variant. Confirm package type and pinout compatibility with target PCB layouts. Ensure design reviews account for the absence of negative voltage requirements compared to predecessor models.

Selection Notes

Select this component when replacing KR3600 units to simplify power supply design by removing negative voltage generation needs. Verify that the application strictly requires keyboard encoding functionality within the signal switch category. Check datasheet specifications for operating voltage ranges and interface compatibility.

Part Context

This part belongs to the KR9600 series produced by Standard Microsystems Corporation (SMSC). The series includes variants such as the KR9600-2672P and KR9600-054. The family focuses on signal switching and decoding logic, with the KR9600-STD specifically noted for its simplified power input configuration relative to earlier generations.

Replacement Considerations

The KR9600-STD is documented as a direct replacement for the KR3600. This substitution removes the need for a separate -12 V power input required by the older model. Verify pin compatibility during integration.
