LSF0102DP-Q100H

Translators, Level Shifters Overview

The LSF0102DP-Q100H is a 2-channel bidirectional multi-voltage level translator in an SOT505-2 (TSSOP8) package. It supports up to 100 MHz up translation and ≥100 MHz down translation at ≤30 pF capacitive load. The device operates with input voltages from 0 V to 7 V, with recommended operating conditions of 0 V to 5 V. It features low standby current, 5 V tolerant I/O pins for TTL compatibility, and flow-through pinout for easy PCB routing. Qualified to AEC-Q100 Grade 1, it functions between -40 °C and +125 °C.

Translators, Level Shifters Procurement Notes

Verify the specific suffix DP indicates the TSSOP8 package variant. Confirm AEC-Q100 Grade 1 qualification status matches project requirements. Ensure supply chain sources provide original manufacturer documentation to validate authenticity. Check for any recent product change notifications that may affect specifications or availability.

Translators, Level Shifters Selection Notes

Select this component when designing circuits requiring flexible bidirectional level shifting between multiple voltage domains such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The absence of a direction control pin simplifies system design. Consider the TSSOP8 package constraints and thermal dissipation limits for high-current applications.

Translators, Level Shifters Part Context

This part belongs to the LSF0102-Q100 family of automotive-grade voltage translators. It shares functional characteristics with the LSF0102DC-Q100 variant, which utilizes a VSSOP8 package. Both variants offer identical electrical performance and are designed for robust signal integrity in mixed-voltage digital environments.

Translators, Level Shifters Replacement Considerations

LSF0102DC-Q100H offers equivalent electrical performance in a VSSOP8 package.
