LSF0204GU12-Q100X

Translators, Level Shifters Overview

The LSF0204GU12-Q100X is a 4-channel bidirectional multi-voltage level translator supporting open-drain and push-pull applications. It operates within an ambient temperature range of -40 °C to +125 °C. The device supports up translation at ≤ 100 MHz with 15 pF or 30 pF capacitive loads, and ≥ 100 MHz down translation under the same conditions. With a 50 pF load, it supports ≤ 50 MHz up translation and ≥ 50 MHz down translation. It accommodates voltage translations between domains such as 0.8 V to 5.0 V, 1.2 V to 5.0 V, 1.8 V to 5.0 V, 2.5 V to 5.0 V, and 3.3 V to 5.0 V. The component utilizes an XQFN-12 package.

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the automotive grade qualification aligns with project requirements. Ensure the input voltage ratings are compatible with the target system logic levels before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring flexible bidirectional translation between various voltage domains without complex control logic. It is suitable for applications needing support for both open-drain and push-pull signaling protocols. Consider the XQFN-12 package constraints regarding board space and thermal dissipation during the layout phase.

Translators, Level Shifters Part Context

This component belongs to the Nexperia LSF0204-Q100 series, which includes variants like the LSF0204PW-Q100 in a TSSOP14 package. The series is designed for automotive-grade reliability, meeting AEC-Q100 Grade 1 standards. It serves as a versatile interface solution for connecting different voltage domains in modern electronic systems.

Translators, Level Shifters Replacement Considerations

The LSF0204PW-Q100 is a confirmed alternative from the same family but uses a TSSOP14 package instead of XQFN-12. Verify pin compatibility and footprint dimensions before substitution.
