UM3308

Overview

The UM3308 is an 8-bit bidirectional voltage-level translator featuring auto direction sensing and ±15kV ESD protection. It facilitates seamless communication between digital components operating at different voltage levels, ensuring reliable data transfer in mixed-voltage systems.

Feature Summary

• Bidirectional voltage translation with automatic direction sensing
• High electrostatic discharge protection rated at ±15kV
• Supports 8-bit parallel data transmission channels

Applications

• Mixed-voltage digital system interconnects
• Embedded controller to peripheral interface bridging
• Industrial automation signal level conversion

Procurement Notes

Verify the specific package variant and temperature grade against your design requirements. Confirm that the ±15kV ESD rating aligns with your environmental standards. Ensure supply chain authenticity through authorized Union Semiconductor distributors to guarantee component reliability and performance consistency.

Selection Notes

Select this component when interfacing logic families with differing voltage thresholds requiring eight simultaneous bidirectional channels. The auto-direction sensing feature simplifies PCB layout by eliminating explicit direction control pins. Verify input/output voltage ranges match the connected devices' specifications for optimal operation.

Part Context

Union Semiconductor designs integrated circuits for linear and mixed-signal applications. The UM3308 belongs to their interface IC portfolio, addressing the need for robust voltage translation in modern electronic devices. This series supports diverse industries by providing reliable connectivity solutions between analog and digital domains.

Replacement Considerations

The TXB0108 from Texas Instruments serves as a public confirmed substitute part number. Both devices offer 8-bit bidirectional translation with auto-direction sensing and similar ESD protection levels. Verify pin compatibility and voltage range specifications before substitution.
