74LVC1G125QW5-7

Overview

The 74LVC1G125QW5-7 is an automotive-compliant single non-inverting buffer with a 3-state output, manufactured by Diodes Incorporated. It operates within a supply voltage range of 1.65V to 5.5V and supports Grade 1 ambient temperature operation from -40°C to +125°C. The device features IOFF circuitry for partial power-down applications, preventing damaging backflow current when powered down. Inputs are tolerant to 5.5V regardless of the VCC level, facilitating mixed-voltage environments. It provides ±24mA output drive at 3.3V and includes ESD protection exceeding 2000V HBM and 1000V CDM per AEC-Q100 standards.

Feature Summary

• AEC-Q100 qualified for Grade 1 automotive applications with PPAP capability
• IOFF circuitry enables safe partial power-down mode operation
• 5.5V tolerant inputs allow compatibility in mixed-voltage systems
• High ESD protection ratings exceeding 2000V Human Body Model

Applications

• Voltage Level Shifting
• Power Down Signal Isolation
• Automotive Applications within Grade 1 Temperature Range
• Industrial Computing/Controls/Automation
• High Reliability Networking/Communications

Procurement Notes

Verify that the specific part number suffix corresponds to the SOT25 package configuration required for the design. Confirm compliance with RoHS 3 and Halogen-free definitions if environmental specifications are mandatory. Ensure the procurement channel is authorized to guarantee product authenticity and traceability. Check for any specific quality certifications or change control requirements associated with automotive-grade components.

Selection Notes

Select this component when an automotive-grade buffer with 3-state output is required for mixed-voltage signal interfacing. The 5.5V input tolerance makes it suitable for translating signals between different logic levels without external components. Consider the wide operating temperature range and high ESD immunity for harsh industrial or automotive environments. Verify that the SOT25 package dimensions fit the available PCB space constraints.

Part Context

This component belongs to the 74LVC1G125Q series, which represents Diodes Incorporated's line of automotive-compliant logic devices. The 'Q' suffix indicates AEC-Q100 qualification, distinguishing it from standard commercial variants. It is part of the broader LVC family designed for low-voltage CMOS applications, offering robust performance in demanding electronic systems requiring high reliability and strict manufacturing controls.

Replacement Considerations

The 74LVC1G125SE-7 is a verified substitute part number within the same series, differing primarily in the SOT353 package type instead of SOT25.
