Nexperia USA Inc. 74LVC3G14GN,115

Overview

74LVC3G14GN,115 from Nexperia is a triple inverting Schmitt trigger IC 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 industrial temperature range (–40 °C to +125 °C) in an XSON8 package (1.2 × 1.0 × 0.35 mm).

For engineers reviewing the 74LVC3G14GN,115 datasheet, 74LVC3G14GN,115 pinout, 74LVC3G14GN,115 application, or 74LVC3G14GN,115 equivalent, key selection criteria include hysteresis voltage (0.40–1.40 V), propagation delay (0.5–6.7 ns), 5 V input tolerance, IOFF-enabled backflow prevention, and compact XSON8 footprint for space-constrained noise-immune timing circuits.

Technical Context

This device implements three independent inverting Schmitt triggers with asymmetric threshold voltages (VT+ and VT−) to convert slow-rising/falling signals into clean digital edges. Each channel provides hysteresis (VH = VT+ − VT−) ranging from 0.40 V to 1.40 V depending on supply voltage, enabling robust noise rejection in environments with EMI or long trace lengths.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow between powered and unpowered sections of a system-critical for hot-swap and partial-power-down architectures. Input clamping diodes and ESD protection (HBM >2000 V, CDM >1000 V) ensure reliability in handling 5 V logic levels while operating from 1.65 V supplies.

FAQ

What is the maximum input frequency this device can reliably condition?

The 74LVC3G14GN,115 does not specify a maximum input frequency, as its function is waveform shaping-not clock distribution. However, with propagation delays as low as 0.5 ns (typical at 5 V), it can cleanly convert input edges with rise/fall times down to ~2 ns. For reliable operation, input transition times should exceed 2× the tpd value under worst-case conditions (e.g., 13.4 ns at 3.0 V/125 °C) to avoid metastability.

Can this part be used with a 1.65 V supply and 5 V input signals simultaneously?

Yes. The 74LVC3G14GN,115 explicitly supports 5 V tolerant inputs across its full 1.65 V–5.5 V VCC range. When VCC = 1.65 V, inputs up to 5.5 V are safely clamped internally without damage or logic misbehavior-enabling direct connection to 5 V microcontroller GPIOs while the IC itself runs from a low-power 1.8 V rail.

How does the IOFF feature behave during power-down sequences?

When VCC drops to 0 V, the IOFF circuit automatically disables all three outputs, limiting leakage current to ≤±2 μA. This prevents current from flowing backward through the outputs into a powered GND plane or other active circuitry-protecting both the 74LVC3G14GN,115 and downstream components during staggered power-down or hot-swap events.

Is the XSON8 package (SOT1116) compatible with standard reflow profiles?

Yes. The SOT1116 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life) and withstands peak reflow temperatures up to 260 °C. Its 0.35 mm profile and copper-leadframe construction ensure uniform thermal transfer, minimizing tombstoning risk when using standard SnAgCu paste and convection reflow profiles.
