UM3302H

Translators, Level Shifters Overview

The UM3302H is a 2-bit bidirectional voltage-level translator manufactured by Union Semiconductor. It features automatic direction sensing to manage signal flow between different voltage domains without requiring a direction control pin. The device provides ±15kV ESD protection on all ports, ensuring robustness in high-static environments. It supports simultaneous conversion across two independent channels, facilitating interface compatibility between low-voltage logic and higher-voltage systems.

Translators, Level Shifters Feature Summary

• Automatic direction sensing eliminates the need for external direction control pins
• Bidirectional translation capability between disparate voltage domains
• High electrostatic discharge protection rating of ±15kV on all ports

Translators, Level Shifters Applications

• Interface bridging between low-voltage microcontrollers and higher-voltage peripherals
• Signal level shifting in mixed-voltage digital communication buses
• Protecting sensitive input/output lines in static-prone industrial environments

Translators, Level Shifters Procurement Notes

Verify the specific package variant and tape-and-reel specifications against the official datasheet before ordering. Confirm that the ±15kV ESD rating aligns with your system's environmental requirements. Ensure voltage levels on both sides fall within the operational limits defined in the electrical characteristics table. Check for any RoHS compliance documentation if required by your manufacturing standards.

Translators, Level Shifters Selection Notes

Select this component when bidirectional data transfer is required without complex control logic. It is suitable for applications needing compact solutions for voltage domain isolation. Consider the channel count; this part offers two bits, which may limit use in wider bus architectures compared to 4-bit or 8-bit variants like the UM3304 or UM3308.

Translators, Level Shifters Part Context

This device belongs to the family of voltage-level translators from Union Semiconductor. It shares functional similarities with industry-standard parts like the Texas Instruments TXB0102 but is distinguished by its specific manufacturer ecosystem. It serves as a passive interface solution for digital signals, differing from active drivers or isolated converters.

Translators, Level Shifters Replacement Considerations

The Texas Instruments TXB0102 is a documented equivalent offering identical 2-bit bidirectional functionality and ±15kV ESD protection. Verify pinout compatibility and operating voltage ranges before substitution.
