UM3304

Overview

The UM3304 is a 4-bit bidirectional voltage-level translator featuring auto direction sensing and ±4kV ESD protection. It facilitates signal translation between different logic voltage domains without requiring external direction control pins.

Feature Summary

• Bidirectional data transfer capability across four independent channels
• Auto direction sensing mechanism eliminates need for explicit direction control signals
• Integrated electrostatic discharge protection rated at ±4kV

Applications

• Interfacing mixed-voltage digital systems
• Level shifting between disparate logic families
• Embedded system communication buses

Procurement Notes

Verify the specific suffix (e.g., Q, T) against the manufacturer datasheet to confirm package type and temperature range. Ensure the component meets required environmental standards for the target application before procurement.

Selection Notes

Select this component when bidirectional translation with automatic direction detection is required. Consider the ±4kV ESD rating for environments with higher static exposure risks compared to standard translators.

Part Context

Union Semiconductor manufactures integrated circuits for linear and mixed-signal applications. The UM3304 belongs to their interface IC portfolio, designed to bridge analog and digital worlds through level translation and protection functions.

Replacement Considerations
