Nexperia USA Inc. 74LVC2G17GM,115

Overview

74LVC2G17GM,115 from Nexperia is a dual non-inverting Schmitt trigger buffer with 5 V tolerant inputs, designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and supports operation from –40 °C to +125 °C in the XSON6 (SOT886) package. It is used in noise-immune waveform shaping for industrial sensor interfaces.

For engineers reviewing the 74LVC2G17GM,115 datasheet, 74LVC2G17GM,115 pinout, 74LVC2G17GM,115 application, or 74LVC2G17GM,115 equivalent, this page provides verified functional role, Schmitt-trigger hysteresis values, IOFF behavior, thermal derating data, and validated alternative parts for voltage translation and noise rejection use cases.

Technical Context

This device implements two independent non-inverting Schmitt-trigger buffers with asymmetric input thresholds (VT+ and VT–) enabling robust noise rejection on slow or noisy signals. Each channel exhibits hysteresis (VH) ranging from 0.40 V to 1.70 V depending on supply voltage, with propagation delay as low as 1.0 ns at VCC = 4.5 V to 5.5 V.

The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V, while inputs remain overvoltage tolerant up to 5.5 V regardless of supply state. Static characteristics include VIH/VIL defined by Schmitt thresholds-not fixed logic levels-ensuring reliable switching across 1.65 V–5.5 V operation.

FAQ

Does 74LVC2G17GM,115 support true 5 V logic input levels when powered from 1.65 V?

Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC value, allowing direct connection to 5 V sources while operating from 1.65 V. This eliminates external level-shifting components and is confirmed in Table 6 (Recommended Operating Conditions) and Section 1 (General Description) of the datasheet.

What is the minimum hysteresis voltage (VH) at VCC = 3.0 V, and how does it affect noise rejection?

The minimum VH at VCC = 3.0 V is 0.40 V (Table 11). This guarantees a noise margin of at least ±200 mV around each switching threshold, enabling reliable operation in environments with >150 mV peak-to-peak coupled noise-verified in static characterization testing across –40 °C to +125 °C.

How does the IOFF feature behave during power sequencing in multi-rail systems?

When VCC drops to 0 V, the IOFF circuit disables both outputs (1Y and 2Y), limiting leakage to ±2 μA maximum (Table 7). This prevents back-current flow from live 5 V buses into the unpowered IC, protecting upstream drivers and meeting IEC 62368-1 safe power-down requirements.

Can 74LVC2G17GM,115 replace 74HC2G17 in existing designs?

Yes, with qualification. Both provide dual Schmitt-trigger buffering, but 74LVC2G17GM,115 operates down to 1.65 V and tolerates 5.5 V inputs-unlike HC-series which requires ≥2 V VCC and lacks overvoltage tolerance. Verify timing (tpd up to 5.4 ns vs HC's ~20 ns) and load drive (±24 mA vs HC's ±4 mA) match your signal integrity requirements.
