74LVC1G17GW,125

Overview

The Nexperia 74LVC1G17GW,125 is a single Schmitt trigger buffer in a TSSOP5 (SOT353-1) package. It operates on a supply voltage range of 1.65 V to 5.5 V with an operating temperature range of -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V and IOFF circuitry for partial power-down applications. Static characteristics include a maximum supply current of 4 μA and input leakage current of ±1 μA at maximum temperatures.

Feature Summary

• Schmitt-trigger action provides high noise immunity and tolerance for slow input rise and fall times.
• IOFF circuitry disables the output during power-down to prevent potentially damaging backflow currents.
• Inputs are overvoltage tolerant to 5.5 V, allowing direct interface with TTL levels and use as translators in mixed voltage environments.

Applications

• Signal buffering in mixed 3.3 V and 5 V logic environments
• Partial power-down mode operation using IOFF circuitry
• Translation between devices driven by different voltage levels

Selection Notes

Select this component when a single-channel non-inverting buffer with hysteresis is required for noisy signal lines or slow edges. The wide supply voltage range supports low-power designs down to 1.65 V. Ensure the application does not require three-state outputs; if bus isolation is needed, consider the 74LVC1G125 series instead. Confirm that the TSSOP5 footprint matches the PCB layout constraints.

Part Context

This part belongs to the Nexperia 74LVC1G17 family of single Schmitt trigger buffers. It is designed for general-purpose digital applications requiring robust signal conditioning. The GW suffix specifically denotes the plastic thin shrink small outline package with 5 leads and a body width of 1.25 mm, suitable for space-constrained surface-mount designs.

Replacement Considerations

Direct pin-compatible replacements within the same package include the 74LVC1G17GV (SC-74A). For automotive applications requiring AEC-Q100 qualification, the 74LVC1G17GW-Q100 is available. Other packages such as XSON variants (e.g., 74LVC1G17GM) offer different form factors but maintain identical electrical functionality.
