Nexperia USA Inc. 74LVC3G14GS,115

Overview

74LVC3G14GS,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 (1.35 × 1.0 × 0.35 mm).

For engineers reviewing the 74LVC3G14GS,115 datasheet, 74LVC3G14GS,115 pinout, 74LVC3G14GS,115 application, or 74LVC3G14GS,115 equivalent, key selection considerations include Schmitt-trigger hysteresis thresholds (VT+ = 1.30–2.40 V, VT− = 0.60–1.70 V at VCC = 3.0–4.5 V), propagation delay (0.5–6.7 ns), 5 V input tolerance, IOFF-enabled backflow prevention, and ultra-compact XSON8 footprint for space-constrained PCBs.

Technical Context

This device implements three independent inverting Schmitt triggers, each with asymmetric hysteresis (VH = 0.40–1.70 V) to convert slow-rising/falling analog-like signals into clean digital outputs. Its IOFF circuit actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V.

The logic function is strictly inverting (L → H, H → L), with input voltage thresholds defined relative to VCC and validated across −40 °C to +125 °C. Input clamping and ESD protection (HBM >2000 V, CDM >1000 V) ensure robustness in noisy environments without external components.

FAQ

Does 74LVC3G14GS,115 support true 5 V operation across its full temperature range?

Yes. The device is fully specified for VCC = 1.65 V to 5.5 V and operates reliably from −40 °C to +125 °C at all voltages within that range. Electrical characteristics-including VOH, VOL, tPD, and hysteresis-are guaranteed across this full window per Table 6 and Table 7 of the Rev. 18 datasheet.

Can the 74LVC3G14GS,115 be used with VCC = 0 V while inputs remain at 5 V?

Yes. When VCC = 0 V, the IOFF circuit disables all outputs, limiting input/output leakage to ±2 μA maximum (Table 7). Inputs tolerate −0.5 V to +6.5 V (Table 5), so 5 V applied to pins 1/3/6 is safe and will not damage the device or back-drive other circuitry.

What is the minimum recommended load capacitance for stable Schmitt-trigger operation?

No minimum load capacitance is required. The device functions correctly with open-drain or high-impedance loads. However, for optimal noise immunity in high-EMI environments, a 10–100 pF local bypass capacitor between VCC and GND near the package is recommended per Nexperia's layout guidelines in Section 13.2 of the datasheet.

How does the hysteresis voltage (VH) vary with supply voltage and temperature?

VH increases with VCC: 0.40 V (min) at VCC = 3.0 V, rising to 1.70 V (max) at VCC = 5.5 V (Table 8). Over temperature, VH remains stable-variation is bounded within ±0.1 V across −40 °C to +125 °C at any given VCC, ensuring consistent noise margin in automotive and industrial deployments.
