UM3304QS

Overview

The UM3304QS is a 4-bit bidirectional voltage-level translator manufactured by Union Semiconductor International Limited. It features auto direction sensing capabilities and integrated electrostatic discharge (ESD) protection rated at ±4kV. The device facilitates signal translation between different logic voltage domains, supporting low-power applications with minimal propagation delay.

Feature Summary

Bidirectional data transfer across four independent channels
Automatic direction sensing eliminates manual control requirements
Integrated ESD protection for enhanced circuit reliability

Applications

Portable consumer electronics
Battery-powered systems
Communication interfaces

Procurement Notes

Verify the manufacturer designation as Union Semiconductor International Limited or Union Semiconductor, Inc., as sources vary. Confirm the specific suffix QS against official datasheets to ensure correct package and temperature grade specifications before procurement.

Selection Notes

Select this component when interfacing circuits with differing supply voltages requiring automatic direction control. Ensure the target application operates within the specified voltage ranges and requires robust ESD protection for portable or exposed environments.

Part Context

This part belongs to the family of voltage-level translators designed for mixed-voltage digital systems. It addresses the need for seamless communication between components operating at different logic levels without external direction control signals.
