LSF0204PWR

Translators, Level Shifters Overview

The LSF0204PWR is a bidirectional multi-voltage level translator manufactured by Texas Instruments. It features four channels within a single circuit, housed in a 14-TSSOP package. The device supports VCCA operation from 0.8 V to 4.5 V and VCCB from 1.8 V to 5.5 V. It provides a data rate of 100 MBd with automatic direction detection. Operating temperatures range from -40°C to +125°C.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation without requiring a dedicated direction control pin
• Supports both open-drain and push-pull output configurations for flexible interface compatibility
• Automatic direction detection minimizes system design complexity and GPIO usage

Translators, Level Shifters Applications

• Interfacing between different logic voltage levels in industrial systems
• Connecting microcontrollers to peripherals using I2C, SMBus, or UART protocols
• GPIO expansion in telecom infrastructure and personal computing devices

Translators, Level Shifters Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-14 package variant. Confirm AEC-Q100 qualification status if automotive compliance is required, as standard commercial versions may differ. Ensure supply chain sources provide original manufacturer documentation to validate authenticity and lot traceability before integration into production designs.

Translators, Level Shifters Selection Notes

Select this component when interfacing between low-voltage logic (down to 0.8V) and 5V tolerant systems. It is suitable for applications requiring bidirectional data flow without explicit direction control. Consider the 14-TSSOP footprint for space-constrained PCB layouts. Verify that the target application's capacitive load remains within specified limits to maintain signal integrity at high speeds.

Translators, Level Shifters Part Context

This part belongs to the LSF0204 family of level translators designed for mixed-voltage environments. It serves as a bridge between disparate digital logic families, enabling communication across varying power domains. The device simplifies system architecture by eliminating the need for external direction control signals, reducing pin count requirements on the host controller.
