Product details
Overview
74LVC3G17GN,115 from Nexperia is a triple non-inverting Schmitt-trigger buffer 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 is qualified from –40 °C to +125 °C in XSON8 (SOT1116) package. It enables robust level translation between 3.3 V and 5 V logic domains in industrial control interfaces.
For engineers reviewing the 74LVC3G17GN,115 datasheet, 74LVC3G17GN,115 pinout, 74LVC3G17GN,115 application, or 74LVC3G17GN,115 equivalent, this device is selected for noise-immune waveform shaping, TTL-level interfacing, and partial-power-down system design-requiring confirmed Schmitt thresholds, hysteresis voltage, IOFF leakage, propagation delay, and XSON8 thermal derating behavior.
Technical Context
This IC integrates three independent Schmitt-trigger buffers, each with asymmetric input thresholds (VT+ and VT−) and defined hysteresis (VH), enabling reliable noise rejection in slow-rising or distorted signals. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during hot-swap or partial power-down sequences.
Input tolerance up to 5.5 V allows direct connection to 5 V sources while powered from 1.65–3.3 V rails, eliminating external level shifters. Static characteristics include sub-1 μA input leakage and <4 μA ICC at VCC = 3.3 V, supporting ultra-low-power operation in battery-backed subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-rail operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families |
| Input Voltage Tolerance | Up to 5.5 V - enables safe interfacing with 5 V peripherals without clamping diodes or resistors |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple CMOS/TTL loads or moderate PCB trace capacitance |
| Propagation Delay | 1.0 ns to 7.1 ns (typ.) - varies with VCC; 3.6 ns typical at 3.3 V, enabling >100 MHz signal edge conditioning |
| Hysteresis Voltage (VH) | 0.40 V to 1.40 V (min–max, VCC = 3.0 V) - ensures ≥400 mV noise margin against EMI-induced false triggering |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - prevents damaging backfeed current during power sequencing or hot-plug events |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-ambient embedded controllers |
Pinout & Package
XSON8 package (SOT1116): extremely thin, leadless, 1.2 mm × 1.0 mm × 0.35 mm body with 8 solderable terminals; optimized for space-constrained PCB layouts and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 3A | Third Schmitt-trigger input - accepts 0–5.5 V signals; internally connected to gate 3 |
| 2 | 3Y | Third Schmitt-trigger output - non-inverting buffered output with rail-to-rail swing |
| 3 | 1Y | First Schmitt-trigger output - independently buffered; shares no internal nodes with other gates |
| 4 | GND | Digital ground reference - must be low-impedance return path for all three buffers |
| 5 | 2Y | Second Schmitt-trigger output - electrically isolated; supports independent load driving |
| 6 | 2A | Second Schmitt-trigger input - identical electrical specs to pins 1 and 7 |
| 7 | 1A | First Schmitt-trigger input - pin 1 indicator located below marking code in lower-left corner |
| 8 | VCC | Positive supply - powers all three gates; IOFF activates when VCC = 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent Schmitt buffers | Three isolated channels enable concurrent noise filtering on separate signal lines without crosstalk |
| 5 V tolerant inputs at any VCC ≥1.65 V | Eliminates need for external level translators when interfacing legacy 5 V sensors or microcontrollers |
| IOFF partial power-down protection | Prevents destructive back-current flow during VCC ramp-down, critical for hot-swap and multi-rail sequencing |
| High noise immunity (≥400 mV hysteresis) | Rejects EMI and ground bounce in motor drives, relay controls, and industrial fieldbus stubs |
| JESD8/JESD36 compliance | Validated interoperability with JEDEC-standard 1.65–5.5 V logic families across temperature extremes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G17DCTR | Same logic function and IOFF, but in larger VSSOP8 (SOT765-1) package (2.3 mm width); higher thermal resistance (4.9 mW/K derating above 99 °C) | Better manual handling and probe access; less suitable for ultra-dense layouts than XSON8 | Select when board assembly uses VSSOP-compatible pick-and-place or requires higher thermal mass for intermittent high-load operation |
| 74LVC1G17GW,125 | Single-channel version in same XSON8 (SOT1116) footprint; identical electrical specs per channel but only one buffer | Lower gate count reduces routing complexity for point-to-point signal conditioning | Select when only one Schmitt input is needed-reduces BOM count and simplifies layout versus unused channels |
Compared with SN74LVC3G17DCTR and 74LVC1G17GW,125, the 74LVC3G17GN,115 uniquely balances triple-channel density, ultra-small XSON8 size, and full 125 °C operation-making it optimal for space- and temperature-constrained multi-signal conditioning where channel count matters.

FAQ
What is the maximum input voltage the 74LVC3G17GN,115 can tolerate when VCC = 1.8 V?
The device supports input voltages up to 5.5 V regardless of VCC level, including at 1.8 V supply. This overvoltage tolerance is enabled by internal protection structures and is validated per JESD8-7 standards. No external clamping is required, allowing direct connection to 5 V sources in mixed-voltage designs.
Does the 74LVC3G17GN,115 support hot-swap operation?
Yes-its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ≤±2 μA. This prevents damage during live insertion into powered backplanes or partial power-down sequences, satisfying hot-swap requirements in modular industrial systems.
How does the Schmitt trigger hysteresis vary with supply voltage?
Hysteresis (VH = VT+ − VT−) increases with VCC: minimum VH is 0.40 V at 3.0 V, rising to 1.40 V at 3.0 V (max), and reaching 1.90 V at 5.5 V. This scaling ensures consistent noise margin across operating rails-critical for reliable edge detection in variable-voltage applications.
Is the XSON8 (SOT1116) package compatible with standard reflow profiles?
Yes-the SOT1116 package is qualified for IPC/JEDEC J-STD-020D reflow, with peak temperature rating of 260 °C. Its 0.35 mm height and thermal derating slope of 4.2 mW/K above 90 °C require attention to local copper pour and adjacent heat sources, but poses no barrier to standard lead-free assembly.
