74LVC3G17DC-Q100H

Overview

The Nexperia 74LVC3G17DC-Q100H is a triple non-inverting Schmitt trigger buffer housed in an 8-lead VSSOP package (SOT765-1). It operates within a supply voltage range of 1.65 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, enabling direct interfacing with TTL levels and mixed 3.3 V/5 V environments. It includes IOFF circuitry for partial power-down protection and meets AEC-Q100 Grade 1 automotive qualification standards.

Feature Summary

• Triple non-inverting buffers with Schmitt-trigger inputs for high noise immunity
• IOFF circuitry prevents damaging backflow current during partial power-down
• Automotive grade qualification compliant with AEC-Q100 Grade 1 standard
• Overvoltage tolerant inputs allow direct interface with 5 V devices

Applications

• Wave and pulse shapers for highly noisy environments
• Mixed 3.3 V and 5 V translation applications
• Automotive electronic systems requiring Grade 1 qualification

Procurement Notes

Verify the specific suffix 'Q100H' to confirm automotive-grade status and temperature range. Ensure the DC variant matches the required VSSOP8 package type. Cross-reference the ordering information table against the latest datasheet revision to confirm availability and compliance with JEDEC standards before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require robust signal conditioning in electrically noisy environments. The inclusion of Schmitt triggers ensures clean output transitions from slow or distorted input signals. Verify that the system's operating voltage falls within the 1.65 V to 5.5 V range and that the thermal environment does not exceed the specified maximum junction temperature limits.

Part Context

This part belongs to the 74LVC3G17-Q100 family of logic ICs manufactured by Nexperia. It is specifically designed for automotive applications where reliability under varying electrical conditions is critical. The device shares functional characteristics with other members of the LVC series but is distinguished by its automotive qualification and specific packaging options.

Replacement Considerations

The 74LVC3G17DP-Q100H serves as a pin-compatible alternative utilizing the TSSOP8 package instead of VSSOP8. Both variants share identical electrical specifications and automotive qualifications. Verify package dimensions and lead pitch compatibility before substituting.
