74LVC1G17W5-7

Overview

The Diodes Incorporated 74LVC1G17W5-7 is a single-input Schmitt-trigger buffer with a standard push-pull output, designed for operation within a power supply range of 1.65V to 5.5V. It features inputs tolerant to 5.5V and includes IOFF circuitry that disables the output during partial power-down applications to prevent damaging current backflow. The device operates across an extended temperature range from -40°C to +125°C and is housed in a compact SOT25 package.

Feature Summary

• Schmitt-trigger input functionality provides noise immunity and signal conditioning
• IOFF circuitry enables safe partial-power-down mode by preventing output backflow
• Inputs accept up to 5.5V, facilitating compatibility in mixed-voltage environments

Applications

• Voltage level shifting between different logic domains
• General purpose logic buffering
• Power down signal isolation

Procurement Notes

Verify the specific ordering suffix W5 corresponds to the SOT25 package configuration required for your design. Confirm compliance with RoHS 3 and Halogen-free standards if mandated by your project specifications. Ensure the component meets AEC-Q100 requirements only if explicitly ordered under the separate automotive-compliant part number 74LVC1G17Q.

Selection Notes

Select this component when a single-channel non-inverting buffer with hysteresis is required. The wide operating voltage range supports low-power designs starting at 1.65V. Consider the SOT25 package dimensions for PCB layout constraints. Verify that the 5.5V input tolerance aligns with the driving source voltage levels in your system architecture.

Part Context

This device belongs to the 74LVC1G series of single-gate logic devices manufactured by Diodes Incorporated. The LVC family is characterized by its low voltage CMOS technology, offering high speed and low power consumption. The 74LVC1G17 specifically implements a Schmitt-trigger buffer function, distinguishing it from standard buffers without hysteresis.

Replacement Considerations

For automotive applications requiring specific change control and IATF 16949 certification, consider the 74LVC1G17Q variant. Other packages within the same logical family include SE (SOT353) and Z (SOT553). Cross-manufacturer equivalents may exist but require verification of pinout and electrical characteristics.
