74LVC2G17GW-Q100H

Overview

The Nexperia 74LVC2G17GW-Q100H is a dual non-inverting Schmitt trigger buffer with 5 V tolerant inputs, designed for automotive applications. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features IOFF circuitry for partial power-down mode operation, preventing backflow current. It provides high noise immunity and direct interface with TTL levels. Propagation delay ranges from 1.0 ns to 13.1 ns depending on voltage and temperature. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Dual non-inverting buffers with Schmitt-trigger inputs for high noise immunity.
• IOFF circuitry enables safe partial power-down mode by disabling outputs.
• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• 5 V tolerant inputs allow direct interfacing between 3.3 V and 5 V devices.

Applications

• Wave and pulse shapers in highly noisy environments.
• Mixed 3.3 V and 5 V logic level translation.
• Automotive electronic systems requiring robust signal conditioning.

Procurement Notes

Verify the specific package variant during procurement, as the GW suffix denotes the TSSOP6 (SOT363-2) package. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design compatibility with the AEC-Q100 Grade 1 qualification if used in automotive contexts. Check for any recent Product Change Notifications regarding marking or packaging updates.

Selection Notes

Select this component when dual-channel buffering with hysteresis is required in space-constrained designs. The 5 V tolerance feature makes it suitable for bridging different voltage domains without additional level shifters. Consider the propagation delay specifications relative to system timing requirements across the full operating voltage and temperature range. Verify input leakage characteristics if low power consumption is critical during standby modes.

Part Context

This part belongs to the Nexperia 74LVC-Q100 family of automotive-grade logic ICs. The series offers various logic functions optimized for low power and high reliability in harsh environments. The 'Q100' designation indicates adherence to strict automotive quality standards, ensuring performance stability over extended temperature ranges and long operational lifetimes typical in vehicle electronics.

Replacement Considerations

Direct replacements include other 74LVC2G17 variants from Nexperia, such as the GV version in SC-74/TSOP6 package. Cross-vendor equivalents must match the dual Schmitt trigger function, 5 V tolerance, and AEC-Q100 qualification. Verify pinout compatibility and electrical parameters before substitution.

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 when connected to live buses.

What is the input voltage tolerance of the 74LVC2G17GW-Q100H?

The inputs are 5 V tolerant, allowing them to be driven from either 3.3 V or 5 V devices safely.
