LSF0108PWR

Translators, Level Shifters Overview

The LSF0108PWR is a bidirectional voltage-level translator manufactured by Texas Instruments. It features one circuit with eight channels, housed in a 20-TSSOP package. The device supports a VCCA range of 0.95 V to 4.5 V and a VCCB range of 1.8 V to 5.5 V. It operates within a temperature range of -40°C to 125°C (TA). Key electrical characteristics include open-drain and push-pull output types. The component is designed for surface mount installation and includes automatic direction detection capabilities.

Translators, Level Shifters Feature Summary

• Bidirectional translation between low-voltage A-side and high-voltage B-side domains
• Automatic direction detection eliminates the need for explicit direction control pins
• Supports both open-drain and push-pull output configurations

Translators, Level Shifters Applications

• Interfacing microcontrollers with peripherals operating at different voltage levels
• Connecting I2C, SMBus, or other multi-master bus systems across voltage boundaries
• Level shifting in mixed-signal embedded systems requiring robust signal integrity

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 20-TSSOP footprint matches your PCB layout requirements. Check for any recent product change notices regarding marking or material composition updates before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic families with significantly different supply voltages, specifically where the A-side drops below 1.8 V while the B-side requires up to 5.5 V. Ensure the application demands bidirectional data flow without manual direction control. Verify that the 8-channel density fits the system architecture and that the TSSOP package is compatible with the assembly process.

Translators, Level Shifters Part Context

This part belongs to the LSF010x family of voltage translators from Texas Instruments. It shares core architectural similarities with variants like the LSF0102 and LSF0108RKSR but differs in package type and pinout configuration. The PWR suffix specifically denotes the 20-lead Thin Shrink Small Outline Package with a 0.65 mm pitch, distinguishing it from QFN or SOIC alternatives.

Translators, Level Shifters Replacement Considerations

Direct substitutes include LSF0108RKSR for a QFN package alternative. Automotive-grade equivalents are available as LSF0108QPWRQ1. Verify pin compatibility and voltage ranges before swapping.
