UM3204QT

Overview

The UM3204QT is a 4-bit bidirectional voltage-level translator manufactured by Union Semiconductor International Limited. Designed for open-drain and push-pull applications, this component facilitates signal translation between different voltage domains. It supports simultaneous data transmission in both directions, allowing independent operation of the A and B ports. The device is engineered to ensure reliable communication across mixed-voltage systems without requiring direction control signals.

Feature Summary

• Supports bidirectional data transmission for open-drain and push-pull configurations
• Enables independent operation of A and B ports for flexible voltage translation
• Eliminates the need for external direction control signals during operation

Applications

• Mixed-voltage system interconnects
• Open-drain bus level shifting
• Push-pull interface translation

Procurement Notes

Verify the specific suffix 'QT' against official Union Semiconductor documentation to confirm package type and temperature grade. Ensure compatibility with target voltage levels before integration. Cross-reference datasheet revisions to confirm pinout consistency. Validate RoHS compliance status through manufacturer declarations. Confirm availability of supporting design files from authorized sources.

Selection Notes

Select this component when bidirectional translation between two voltage domains is required without direction control overhead. Suitable for systems utilizing open-drain or push-pull interfaces. Verify that the operating voltage range matches the connected logic levels. Consider pin count and package constraints for PCB layout. Evaluate noise immunity requirements for the specific application environment.

Part Context

This part belongs to the UM320x series of voltage translators from Union Semiconductor. The series includes variants such as UM3202 (2-bit) and UM3208 (8-bit). These devices are designed to simplify interface design in multi-voltage environments. The family focuses on low-power operation and minimal external component requirements.

Replacement Considerations

The TXS0104E from Texas Instruments is a documented equivalent in the same category. Verify pin-to-pin compatibility and voltage specifications before substitution. Check for differences in propagation delay and leakage current characteristics.
