UM3308UK

Overview

The UM3308UK is an 8-bit bidirectional voltage-level translator manufactured by Union Semiconductor. It features auto direction sensing to manage signal flow without a dedicated direction control pin. The device provides ±15kV ESD protection on its I/O pins, ensuring robustness in electrically noisy environments. Designed for low-power applications, it supports flexible voltage translation between different logic families and systems.

Feature Summary

• Auto direction sensing eliminates the need for external direction control pins
• Bidirectional data transfer across multiple voltage domains
• High electrostatic discharge tolerance on all input and output pins

Applications

• Interfacing between microcontrollers and peripheral devices with differing supply voltages
• Level shifting in mixed-voltage digital systems
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific suffix UK against the manufacturer's official datasheet to confirm package type and temperature range. Ensure compatibility with system voltage levels before integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing circuits that require automatic direction control for bidirectional buses. It is suitable for replacing manual direction-control translators where pin count reduction is critical. Verify that the target application does not require isolated communication channels.

Part Context

This part belongs to Union Semiconductor's interface product line, specifically within the voltage translator category. It complements other level-shifting solutions by offering integrated direction sensing. The family includes variants with different bit widths and ESD ratings.
