Product details
Overview
74AHC3G14GT,115 from Nexperia is a triple inverting Schmitt trigger IC with overvoltage-tolerant inputs (up to 5.5 V), CMOS-level input compatibility, and operation across 2.0 V–5.5 V supply. It delivers symmetrical output impedance, balanced propagation delays (as low as 3.2 ns at VCC = 5.0 V, CL = 15 pF), and hysteresis of 0.45–1.6 V-enabling reliable waveform shaping in noisy industrial sensor interfaces.
For engineers reviewing the 74AHC3G14GT,115 datasheet, 74AHC3G14GT,115 pinout, 74AHC3G14GT,115 application, or 74AHC3G14GT,115 equivalent, this device serves as a robust signal conditioner for slow-rising inputs in motor control feedback paths, microcontroller GPIO debouncing, and relaxation oscillator timing circuits where noise immunity and voltage translation are critical.
Technical Context
The 74AHC3G14GT implements three independent Schmitt-trigger inverters in a single XSON8 package. Each channel features distinct positive-going (VT+) and negative-going (VT−) input thresholds-e.g., VT+ = 3.85 V and VT− = 1.65 V at VCC = 5.5 V-producing 2.2 V hysteresis that rejects sub-threshold noise without external components.
Its overvoltage-tolerant inputs allow direct interfacing between 3.3 V logic domains and 5 V systems without level shifters. The device maintains stable switching behavior across −40 °C to +125 °C ambient, with static current consumption below 40 μA at VCC = 5.5 V and dynamic power dissipation modeled via CPD = 10 pF per buffer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports mixed-voltage board designs without dedicated regulators |
| Input Threshold Hysteresis (VH) | 0.45 V to 1.6 V - ensures noise margins ≥450 mV in high-EMI environments like motor drives |
| Propagation Delay (tpd) | 3.2 ns (typ) at VCC = 5.0 V, CL = 15 pF - enables clean edge regeneration for clock-like signals |
| Output Drive Strength | ±8 mA at VOH/VOL - sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF) |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial PLC I/O stages |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces need for external TVS diodes in handling-sensitive assembly lines |
| Power Dissipation Cap | 250 mW (Tamb ≤68 °C) - defines thermal derating limit for continuous operation in sealed enclosures |
Pinout & Package
XSON8 plastic extremely thin small outline package (SOT833-1); 8-terminal, leadless, 1.0 × 1.95 × 0.5 mm body; pin 1 index located on lower-left corner beneath marking code "A14".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Independent input terminals | Accept overvoltage-tolerant CMOS-level signals; each triggers its own inverting Schmitt path |
| 1Y, 2Y, 3Y | Corresponding inverted outputs | Provide rail-to-rail CMOS-compatible outputs with matched rise/fall times |
| VCC | Positive supply | Single supply powers all three channels; no separate VDD/VSS per gate required |
| GND | Ground reference | Common return for all inputs, outputs, and internal bias networks |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tr ≈ tf), minimizing duty-cycle distortion in oscillator loops |
| Overvoltage-tolerant inputs | Withstands up to 5.5 V regardless of VCC setting-allows safe interfacing with 5 V sensors on 3.3 V MCU boards |
| Wide temperature range | Specified from −40 °C to +125 °C-supports deployment in engine control units and outdoor industrial gateways |
| Low static current | ICC ≤ 40 μA at VCC = 5.5 V-reduces quiescent load in battery-backed monitoring nodes |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A-ensures robustness against transient ground bounce events |
Applications
| Motor Control Feedback Conditioning | Microcontroller GPIO Debouncing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT3G14GT,115 | TTL-level inputs (VIH = 2.0 V min), identical package and pinout | Better compatibility with legacy 5 V TTL logic families; slightly higher ICC at VCC = 5.5 V | Select when interfacing with older 74LS/74F series or when VIH threshold must be ≤2.0 V |
| SN74LVC3G14DCUR | Lower VCC range (1.65–5.5 V), LVC logic family, same XSON8 footprint but different pin mapping | Supports 1.8 V MCU domains; requires PCB redesign due to non-identical pinout (e.g., GND at Pin 4 vs. Pin 8) | Select only if migrating to 1.8 V systems and redesigning layout; not drop-in compatible |
Compared with 74AHCT3G14GT,115, the 74AHC3G14GT,115 offers superior noise immunity in mixed-voltage sensor front-ends due to higher VT+ thresholds, while SN74LVC3G14DCUR enables lower-voltage operation at the cost of layout rework and reduced hysteresis margin.

FAQ
What is the maximum input voltage the 74AHC3G14GT,115 can tolerate?
The 74AHC3G14GT,115 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level-enabling safe connection to 5 V sources even when powered from 3.3 V or 2.5 V rails. This eliminates the need for external clamping diodes in mixed-voltage signal routing.
Can the 74AHC3G14GT,115 operate reliably at 125 °C junction temperature?
Yes-the device is fully specified from −40 °C to +125 °C ambient, with validated performance including propagation delay, hysteresis, and output drive strength across that full range. Its XSON8 package has a thermal resistance (RθJA) of ~220 K/W, supporting sustained operation at 125 °C with appropriate PCB copper area.
How does the Schmitt trigger hysteresis improve noise rejection compared to a standard inverter?
Unlike standard inverters with a single switching threshold, the 74AHC3G14GT uses separate VT+ (e.g., 3.85 V) and VT− (e.g., 1.65 V) thresholds-creating a 2.2 V hysteresis window. Signals must cross both thresholds to toggle output state, rejecting noise spikes smaller than the hysteresis voltage without false triggering.
Is the 74AHC3G14GT,115 pin-compatible with other packages in the same logic family?
No-the XSON8 (SOT833-1) pinout differs from TSSOP8 (SOT505-2) and VSSOP8 (SOT765-1) variants. For example, GND is at Pin 4 in VSSOP8 but Pin 8 in XSON8, and input/output terminal ordering is rotated. Layout reuse requires package-specific footprint validation.
