Product details
Overview
74LVC3G17GD,125 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 supply, 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 XSON8 package.
For engineers reviewing the 74LVC3G17GD,125 datasheet, 74LVC3G17GD,125 pinout, 74LVC3G17GD,125 application, or 74LVC3G17GD,125 equivalent, this device is selected for noise-immune waveform shaping, level translation between 3.3 V and 5 V logic domains, and robust interface buffering where hysteresis prevents chatter in noisy environments.
Technical Context
The 74LVC3G17GD,125 implements three independent Schmitt-trigger input buffers with non-inverting transfer characteristics, enabling clean digital signal regeneration from slow or noisy analog-like waveforms. Its input threshold hysteresis (VH = 0.40–1.90 V, depending on VCC) ensures stable switching despite slow edge rates or EMI-induced fluctuations.
IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and multi-rail system integrity. Inputs tolerate up to 5.5 V regardless of VCC, allowing direct interfacing with legacy 5 V TTL or CMOS sources while powered from 1.65–3.3 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection to 5 V sources without external level shifters |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or moderate capacitive traces |
| Hysteresis Voltage (VH) | 0.40 V (min) to 1.90 V (max), scalable with VCC - rejects noise spikes up to ~1.9 V peak-to-peak |
| Propagation Delay | 1.0 ns (min) to 5.4 ns (max), dependent on VCC - supports >100 MHz signal conditioning in high-speed digital interfaces |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - prevents damaging back-current during power sequencing |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial control units |
Pinout & Package
XSON8 (SOT996-2) package: plastic extremely thin small outline, no leads, 8 terminals, body size 1.0 × 1.45 × 0.5 mm, wettable flank design for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Independent Schmitt-trigger inputs | Three separate buffered inputs accepting 0–5.5 V signals; each triggers its corresponding output on rising/falling thresholds |
| 1Y, 2Y, 3Y | Non-inverting buffered outputs | Three CMOS-compatible outputs replicating input state with hysteresis; drive strength scales with VCC |
| VCC | Positive supply rail | Single supply pin powering all three buffers; IOFF activates automatically when pulled to 0 V |
| GND | Reference ground | Common return path for all inputs, outputs, and internal logic; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger buffer | Three independent channels in one die - reduces board space vs. discrete solutions and eliminates inter-channel skew |
| 5 V tolerant inputs | Operates with VCC as low as 1.65 V while accepting 5 V inputs - eliminates need for external translators in mixed-voltage designs |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V - prevents backfeed into powered subsystems during hot-plug or sleep mode |
| High noise immunity | Typical hysteresis ≥0.73 V at 3.0 V - suppresses false triggering from ESD transients or crosstalk in motor-drive or sensor interfaces |
| JEDEC-compliant ESD protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 3 requirements for production handling and end-equipment robustness |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|

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 | VSSOP8 package (2.3 mm width); identical electrical specs; slightly higher thermal resistance (4.9 mW/K derating above 99 °C) | Better suited for manual prototyping due to larger pitch; less suitable for ultra-dense layouts | Select when board assembly uses fine-pitch reflow but requires easier visual inspection or hand-soldering capability |
| 74LVC1G17GW,125 | Single-channel version in same XSON8 package; identical per-channel performance; lower pin count and footprint | Used where only one Schmitt buffer is needed - avoids overdesign and saves PCB area | Select for minimal channel count requirements or when scaling channel density independently per function block |
Compared with SN74LVC3G17DCTR and 74LVC1G17GW,125, the 74LVC3G17GD,125 uniquely balances triple-channel density, ultra-compact XSON8 packaging, and full 5 V tolerance - making it optimal for space-constrained, mixed-voltage embedded controllers requiring parallel signal conditioning.

FAQ
What is the maximum input voltage the 74LVC3G17GD,125 can safely accept?
The 74LVC3G17GD,125 accepts input voltages up to 5.5 V regardless of VCC level, as confirmed in Table 5 (Limiting Values) and Table 6 (Recommended Operating Conditions). This 5 V tolerance is maintained even when VCC is as low as 1.65 V, enabling direct interfacing with legacy 5 V logic without external components.
Does the 74LVC3G17GD,125 support partial power-down operation?
Yes - the device integrates IOFF circuitry that places outputs in high-impedance state when VCC = 0 V, preventing destructive backflow current. This is explicitly specified in Section 1 (General description) and Table 7 (Static characteristics), with IOFF leakage ≤ ±2 μA at VCC = 0 V and VI/VO = 5.5 V.
What is the typical hysteresis voltage at 3.3 V supply?
At VCC = 3.3 V, the typical hysteresis voltage (VH) is 0.92 V, derived from VT+ = 2.47 V and VT− = 1.55 V (Table 8, Transfer Characteristics). This value ensures strong noise rejection for signals with amplitude variations up to ~900 mV peak-to-peak in industrial environments.
Which package variant corresponds to the 74LVC3G17GD,125 ordering code?
The 74LVC3G17GD,125 uses the XSON8 package (SOT996-2), a leadless 1.0 × 1.45 × 0.5 mm body with wettable flanks. This is confirmed in the Revision History (Section 15), where v.13 notes removal of SOT902-2 and v.10 confirms "XSON8U has changed to XSON8", aligning GD with the standard XSON8 footprint.
