74LVC2G17GW,125

Overview

The Nexperia 74LVC2G17GW,125 is a dual non-inverting Schmitt trigger buffer housed in a TSSOP6 (SOT363-2) 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 provides high noise immunity and supports partial power-down mode via IOFF circuitry. Propagation delay ranges from 1.0 ns to 8.5 ns depending on voltage and temperature. It complies with JEDEC standards for various voltage levels and offers ESD protection exceeding 2000 V (HBM).

Feature Summary

• Dual non-inverting buffers with Schmitt-trigger inputs for high noise immunity.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow direct interfacing with 3.3 V or 5 V devices.

Applications

• Wave and pulse shapers for highly noisy environments.
• Translators in mixed 3.3 V and 5 V logic environments.

Procurement Notes

Verify the specific ordering suffix '125' against the manufacturer's latest documentation to confirm packaging details such as reel size or tape specifications. Ensure the TSSOP6 package variant matches the required PCB footprint dimensions. Confirm compliance requirements including RoHS status and halogen-free definitions prior to final procurement authorization.

Selection Notes

Select this component when dual buffering with hysteresis is required in space-constrained designs. The TSSOP6 package is suitable for surface-mount applications requiring thin profiles. Consider the wide operating temperature range and low static power consumption for portable or industrial systems. Verify that the input voltage tolerance aligns with the source driver levels.

Part Context

This part belongs to the 74LVC family of CMOS logic devices, designed for low-voltage operation. The 74LVC2G17 series specifically provides dual Schmitt trigger functionality. The GW suffix denotes the TSSOP6 plastic thin shrink small outline package. It is manufactured by Nexperia USA Inc. and is intended for general-purpose digital signal conditioning.

Replacement Considerations

Check for equivalent parts within the same 74LVC family offering identical pinouts and electrical characteristics. Verify package compatibility if substituting with variants like the GV (SC-74) version. Ensure any replacement maintains the required Schmitt trigger action and IOFF functionality for partial power-down support.

FAQ

How does the IOFF circuitry function in this device?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device even if inputs are at 5.5 V while VCC is 0 V.

What is the input voltage tolerance of the 74LVC2G17GW?

The inputs are overvoltage tolerant up to 5.5 V, allowing them to be driven by 3.3 V or 5 V devices without damage.
