74LVC1G240GW-Q100H

Overview

The Nexperia 74LVC1G240GW-Q100H is a single inverting buffer and line driver featuring three-state outputs, housed in a TSSOP5 (SOT353-1) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an input voltage up to 5.5 V. The device provides ±24 mA output drive capability at 3.0 V and includes IOFF circuitry for partial power-down mode operation. It is qualified to AEC-Q100 Grade 1 standards and functions reliably across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• IOFF circuitry enables partial power-down mode to prevent backflow current
• Schmitt-trigger inputs provide tolerance for slow rise and fall times
• Overvoltage tolerant inputs allow direct interface with 3.3 V and 5 V devices

Applications

• Automotive electronic systems requiring robust logic buffering
• Mixed 3.3 V and 5 V voltage domain translation applications
• Partial power-down scenarios utilizing IOFF functionality
• High noise immunity signal transmission environments

Procurement Notes

Verify the specific ordering suffix 'H' against the manufacturer's official documentation to confirm packaging details such as reel or cut tape configuration. Ensure the component meets the required AEC-Q100 Grade 1 automotive qualification standards for your specific application environment. Cross-reference the SOT353-1 package dimensions with your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a single-channel inverting buffer with three-state control is required for automotive or industrial designs. It is suitable for interfacing between different voltage domains due to its overvoltage tolerant inputs. Consider the TSSOP5 package constraints and the specified operating temperature range of -40 °C to +125 °C during the design phase to ensure compatibility with system thermal and spatial requirements.

Part Context

This device belongs to the Nexperia 74LVC1G240-Q100 family of single-function logic ICs. It is part of the broader LVC logic series designed for low-voltage CMOS applications. The product is manufactured by Nexperia USA Inc. and is distinct from non-automotive variants by its adherence to AEC-Q100 reliability standards. The GW suffix specifically denotes the TSSOP5 plastic thin shrink small outline package type.

Replacement Considerations

Consult the manufacturer's official replacement guide for verified substitute part numbers. Ensure any alternative component matches the AEC-Q100 Grade 1 qualification and maintains the same TSSOP5 pinout and electrical characteristics for direct integration.
