LSF0108RKSR

Translators, Level Shifters Overview

The LSF0108RKSR is an automotive-grade, eight-channel bidirectional voltage-level translator manufactured by Texas Instruments. It operates within a supply voltage range of 0.95 V to 4.5 V on the A side and 1.8 V to 5.5 V on the B side. The device utilizes transmission gate technology with open-drain or push-pull outputs. It supports data rates up to 110 Mb/s and features automatic direction detection. Operating temperatures range from -40°C to +125°C in a 20-VQFN package.

Translators, Level Shifters Feature Summary

• Automatic direction detection for seamless bidirectional signal translation without explicit control pins
• Supports wide voltage differential between A-side (0.95V-4.5V) and B-side (1.8V-5.5V) supplies
• Automotive qualification compliant for reliable operation in harsh environments
• Low quiescent current consumption suitable for power-sensitive applications

Translators, Level Shifters Applications

• Interfacing low-voltage microcontrollers with higher-voltage peripherals in automotive systems
• Bidirectional level shifting for I2C, SPI, and other multi-master bus protocols
• Voltage translation between different logic families in mixed-signal circuits

Translators, Level Shifters Procurement Notes

Verify the Q1 suffix indicates automotive grade compliance per TI specifications. Confirm the RKSR suffix corresponds to the 20-VQFN package with tape-and-reel delivery. Ensure design reviews account for the specified operating temperature range and supply voltage constraints. Cross-reference datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation is required between dissimilar voltage domains without complex control logic. The automatic direction feature simplifies PCB layout compared to unidirectional translators. Verify that the target application's signal frequencies remain within the supported data rate limits. Consider the VQFN package size constraints during mechanical design integration.

Translators, Level Shifters Part Context

This part belongs to the LSF010x family of voltage-level translators designed for bidirectional communication. It serves as a bridge between low-voltage digital logic and higher-voltage interfaces. The automotive variant ensures reliability under extended temperature ranges and vibration conditions typical in vehicle electronics.

Translators, Level Shifters Replacement Considerations

LSF0108RKS is the non-reel version of the same device. TXS0108EQWRKSRQ1 is an automotive-grade alternative but lacks automatic direction detection. Verify pin compatibility and electrical characteristics before substitution.
