74LVC1G17GX4Z

Overview

The Nexperia 74LVC1G17GX4Z is a single Schmitt trigger buffer housed in an X2SON4 (SOT1269-2) package. It operates within a supply voltage range of 1.65 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device includes IOFF circuitry for partial power-down mode, preventing backflow current. It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36. Static characteristics specify input leakage current at ±1 μA maximum and supply current at 4 μA maximum. Dynamic propagation delay ranges from 0.7 ns to 14.0 ns depending on voltage and temperature.

Feature Summary

• Single Schmitt trigger buffer configuration
• IOFF circuitry for partial power-down protection
• Overvoltage tolerant inputs compatible with 5 V devices
• Direct interface capability with TTL levels

Applications

• Signal translation between mixed 3.3 V and 5 V environments
• Wave shaping of slow or noisy input signals
• Partial power-down applications requiring output disablement

Procurement Notes

Verify the specific ordering suffix GX4 corresponds to the X2SON4 (SOT1269-2) package variant. Confirm that the required temperature range matches the specified -40 °C to +125 °C operational limits. Ensure design compatibility with the 5-terminal pinout structure defined for this package type. Cross-reference the marking code VJ with physical component inspection upon receipt.

Selection Notes

Select this component when a single-channel Schmitt trigger is required in a minimal footprint. The X2SON4 package offers thermal enhancement suitable for space-constrained designs. Consider the 1.65 V to 5.5 V operating range for flexibility across different logic families. Verify that the input signal amplitude falls within the overvoltage tolerance specifications for reliable operation.

Part Context

This part belongs to the 74LVC1G17 family of single Schmitt trigger buffers manufactured by Nexperia. The family supports multiple package options including TSSOP5, SC-74A, and various XSON variants. The GX4 suffix specifically denotes the X2SON4 plastic thermal enhanced extremely thin small outline package with no leads and four terminals.

Replacement Considerations

The 74LVC1G17GX4 is a direct predecessor to the 74LVC1G17GX4Z, sharing identical electrical specifications and functionality. Both utilize the X2SON4 package. Verify package marking codes and terminal configurations to ensure mechanical interchangeability during replacement.
