LSF0204RUTR

Translators, Level Shifters Overview

The LSF0204RUTR is a bidirectional multi-voltage level translator manufactured by Texas Instruments. It features four channels within a UQFN-12 package, supporting supply voltages from 1 V to 5.5 V. The device exhibits a propagation delay of 1.5 ns and operates with a working power current of 3.5 uA. It accepts CMOS and TTL inputs, providing TTL outputs suitable for various logic interfaces. The component functions across an extended temperature range from -40 C to +125 C.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation capability without requiring a dedicated direction control pin
• Supports multiple voltage domains including 1.8 V, 2.5 V, 3.3 V, and 5.0 V
• Compatible with both open-drain and push-pull signal applications

Translators, Level Shifters Applications

• GPIO interface translation in telecom infrastructure
• MDIO and PMBus protocol level shifting
• SMBus and I2C bus voltage conversion
• UART and SDIO interface adaptation

Translators, Level Shifters Procurement Notes

Verify the specific suffix RUTR corresponds to the UQFN-12 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal performance specifications for the intended operating environment.

Translators, Level Shifters Selection Notes

Select this component for designs requiring flexible multi-voltage translation between disparate logic families. The absence of a direction pin simplifies PCB layout and reduces control signal requirements. Verify that the target application does not exceed the specified capacitive load limits to maintain signal integrity at the desired data rates.

Translators, Level Shifters Part Context

This part belongs to the LSF0204 series of low-power, bidirectional translators designed for mixed-voltage systems. It serves as a solution for interfacing components operating at different supply rails without complex external circuitry. The series supports hot insertion and offers robust ESD protection characteristics.

Translators, Level Shifters Replacement Considerations

LSF0204PWR: Same functional family but utilizes a TSSOP-14 package instead of UQFN-12.
