74LV1T125GW-Q100H

Overview

The Nexperia 74LV1T125GW-Q100H is a single supply translating buffer and line driver featuring a 3-state output, housed in a TSSOP5 (SOT353-1) package. It supports a supply voltage range of 1.6 V to 5.5 V with 5 V tolerant inputs. The device facilitates level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V CMOS levels. Propagation delay ranges from 3.2 ns to 11.6 ns depending on load capacitance and voltage. It operates within an ambient temperature range of -40 °C to +125 °C and meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Supports bidirectional level translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic levels using a single supply voltage.
• Features 5 V tolerant input pins that enable down translation from higher voltage domains.
• Includes a 3-state output controlled by an OE input to manage high-impedance OFF-states.
• Provides robust ESD protection exceeding 2000 V via HBM and 1000 V via CDM standards.

Applications

• Telecom infrastructure
• Portable applications
• PC and notebooks
• Industrial controller

Procurement Notes

Verify the specific suffix 'Q100H' against official Nexperia documentation to confirm it denotes the standard tape-and-reel packaging format rather than a variant with different electrical characteristics. Ensure the ordering code matches the required SOT353-1 package type. Confirm compliance requirements such as RoHS status directly with the manufacturer's current product data sheet before finalizing procurement specifications.

Selection Notes

Select this component when interfacing circuits operating at different voltage levels, specifically requiring translation between 1.8 V and 5.0 V domains. The wide supply voltage range accommodates various system power rails. Consider the 3-state capability if bus sharing or tri-state control is necessary. Verify that the propagation delay and drive strength meet the timing requirements of the target application interface.

Part Context

This part belongs to the 74LV1T125-Q100 family of single-supply translating buffers. It shares functional similarities with other level translators but is distinguished by its specific 5 V tolerance and single-channel configuration. The Q100 designation indicates automotive-grade qualification, while the GW suffix specifies the thin shrink small outline plastic package.

Replacement Considerations

Check for direct equivalents within the 74LV1T125 series from Nexperia or cross-reference with other manufacturers offering single-supply translating buffers with 3-state outputs. Ensure any substitute maintains the same AEC-Q100 Grade 1 qualification and compatible pinout for the SOT353-1 package.

FAQ

Can the 74LV1T125GW-Q100H perform up translation?

Yes, the device supports up translation, such as converting 1.8 V input signals to 3.3 V outputs when powered by a 3.3 V supply.

What is the function of the OE pin?

The OE (Output Enable) pin controls the 3-state output. A HIGH level at OE causes the output to assume a high-impedance OFF-state.
