74LVC1G17QW5-7

Overview

The Diodes Incorporated 74LVC1G17QW5-7 is an automotive-compliant, single-input Schmitt trigger buffer featuring a standard push-pull output. Designed for operation within a power supply range of 1.65V to 5.5V, the device incorporates I_OFF circuitry to support partial power-down applications by disabling outputs and preventing damaging current backflow. The inputs are tolerant to 5.5V regardless of the VCC level, facilitating use in mixed-voltage environments. It operates across Grade 1 ambient temperatures from -40°C to +125°C.

Feature Summary

• AEC-Q100 qualified with PPAP capability for automotive applications
• Schmitt trigger input provides noise filtering and signal conditioning
• IOFF circuitry enables safe partial power-down mode operation
• Inputs accept up to 5.5V independent of the supply voltage level

Applications

• Voltage level shifting between different logic families
• Power down signal isolation in mixed-voltage systems
• General purpose logic buffering in industrial computing and controls
• High reliability networking and communications equipment

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the Q series includes both SOT25 (W5) and SOT353 (SE) variants. Confirm compliance requirements such as RoHS 3 and Halogen-free status directly with the manufacturer documentation. Ensure design specifications align with the AEC-Q100 qualification standards required for the target application environment.

Selection Notes

Select this component when an automotive-grade buffer with Schmitt trigger characteristics is required. The wide supply voltage range supports various digital logic levels. The inclusion of IOFF functionality makes it suitable for systems requiring controlled power-down states without external switching components. Verify thermal resistance values against the specific PCB layout and copper weight used in the design.

Part Context

This part belongs to the 74LVC1G17Q family of single Schmitt trigger buffers manufactured by Diodes Incorporated. The 'Q' designation indicates AEC-Q100 qualification for automotive use. The W5 suffix specifically identifies the SOT25 surface-mount package. This family is designed for low-power consumption while maintaining high-speed performance in compact form factors.

Replacement Considerations

The 74LVC1G17QSE-7 serves as a package alternative within the same electrical specification family, utilizing the SOT353 footprint instead of SOT25. Cross-referencing with other manufacturers requires verifying pin compatibility, voltage tolerances, and Schmitt trigger thresholds.
