Product details
Overview
74LVC1G17GV,125 from Nexperia is a single Schmitt-trigger buffer IC designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, accepts overvoltage-tolerant inputs up to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is qualified for -40 °C to +125 °C operation in SC-74A (SOT753) package.
For engineers reviewing the 74LVC1G17GV,125 datasheet, 74LVC1G17GV,125 pinout, 74LVC1G17GV,125 application, or 74LVC1G17GV,125 equivalent, this device serves as a robust level-translating buffer in noise-prone environments-especially where hysteresis-based noise immunity, rail-to-rail input compatibility, and low-power shutdown behavior are required.
Technical Context
The 74LVC1G17GV,125 implements a non-inverting Schmitt-trigger transfer function with programmable hysteresis (VH = 0.4–0.88 V depending on VCC), enabling reliable signal restoration of slow or noisy digital edges. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
It supports direct interface with TTL logic levels and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V supply range. Propagation delay ranges from 0.7 ns (min) to 7.0 ns (max) at 3.0–3.6 V, with typical CPD = 16.6 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - enables interoperability between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| Input Voltage Range | 0 V to 5.5 V - overvoltage-tolerant inputs allow safe connection to 5 V sources even when powered at 1.65 V |
| Hysteresis Voltage (VH) | 0.41 V to 0.88 V - provides noise margin against false triggering on slow or degraded waveforms |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC loads or moderate PCB traces without external buffering |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - ensures minimal backfeed current during hot-swap or partial power-down sequences |
| Propagation Delay | 0.7 ns (min) to 7.0 ns (max) at 3.0–3.6 V - balances speed and noise immunity for general-purpose signal conditioning |
| Operating Temperature | -40 °C to +125 °C - supports automotive under-hood, industrial control, and high-reliability embedded applications |
Pinout & Package
74LVC1G17GV,125 is housed in the SC-74A (SOT753) surface-mount package: plastic, 5-lead, body size 3.1 mm × 1.7 mm × 1.3 mm, with gull-wing leads and pin 1 marked by a dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (n.c.) | No-connect terminal | Internally unconnected; must remain floating or grounded per layout best practice-no routing or soldering required |
| 2 (A) | Data input | Schmitt-triggered input accepting 0–5.5 V; threshold hysteresis prevents chatter on slow-rising/falling signals |
| 3 (GND) | Ground reference | Primary 0 V return path; requires low-inductance connection to system ground plane for noise immunity |
| 4 (Y) | Data output | Inverting logic function not present-output is true (non-inverting) buffer with rail-to-rail swing |
| 5 (VCC) | Supply voltage | Power input for internal CMOS circuitry; decoupling capacitor (100 nF) recommended within 3 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65–5.5 V operation allows use across legacy 5 V and modern ultra-low-voltage systems without level shifters |
| IOFF partial power-down | Disables output and blocks backflow current when VCC = 0 V-critical for hot-plug and multi-rail sequencing |
| High noise immunity | Typical hysteresis of 0.6 V at 3.0 V supply rejects >300 mV of superimposed noise on input signals |
| ±24 mA drive capability | Supports fan-out of ≥10 LVC gates or direct driving of 50 Ω transmission lines at 3.0 V |
| JEDEC-compliant I/O | Fully compatible with TTL input thresholds and LVTTL output levels-no external pull-ups or translators needed |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, potentiometer) before ADC sampling in noisy factory environments. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow-rising analog comparator outputs into clean digital edges for microcontroller GPIO capture. Use Value: Eliminates contact bounce and EMI-induced glitches without software debouncing-reducing firmware overhead and improving real-time response. | Use Scenario: Interfacing door lock switch signals to a 3.3 V body controller MCU in vehicles with 12 V battery-supplied sensors. IC Role / Device Role / Timing Role: Level-translating buffer accepts 12 V switch inputs (via resistor divider) and drives 3.3 V MCU inputs with hysteresis for vibration immunity. Use Value: Enables direct integration of legacy 12 V mechanical switches without dedicated voltage translators or custom RC filters. |
| USB-C Power Delivery Monitor | Programmable Logic Controller I/O Expansion |
Use Scenario: Detecting CC line state transitions in USB-C PD controllers where VBUS presence must trigger fast, glitch-free enable signals. IC Role / Device Role / Timing Role: Input conditioner for CC pin detection logic-converts slow, capacitively loaded CC line edges into monotonic, jitter-free pulses. Use Value: Prevents false PD negotiation starts due to cable insertion bounce or ESD transients-ensuring reliable port enumeration. | Use Scenario: Buffering discrete I/O signals from field devices (e.g., proximity sensors, limit switches) into a 24 V PLC backplane running at 3.3 V logic. IC Role / Device Role / Timing Role: Isolating and translating 24 V dry-contact inputs to 3.3 V logic-compatible levels while suppressing electrical noise from motor drives. Use Value: Replaces optocouplers in cost-sensitive modules-reducing BOM count, board area, and power consumption while maintaining noise rejection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | TI part in SOT-23-5 (same pinout); identical VCC range and hysteresis but higher ICC (max 10 μA vs. 4 μA) | Higher static current may impact battery-powered designs; otherwise drop-in compatible in most 3.3 V systems | Select if TI ecosystem alignment or existing DBVR footprint reuse is prioritized over ultra-low quiescent current |
| 74AUP1G17GW,125 | Nexperia AUP variant in TSSOP5; lower VCC min (0.8 V), lower drive (±4 mA), and reduced hysteresis (0.2 V typ) | Optimized for sub-1.2 V logic; unsuitable for 5 V-tolerant or high-drive applications requiring 74LVC1G17GV,125's specs | Choose only for ultra-low-power, single-supply <1.2 V systems-avoid where 5 V tolerance or 24 mA drive is needed |
Compared with SN74LVC1G17DBVR and 74AUP1G17GW,125, the 74LVC1G17GV,125 uniquely balances 5 V input tolerance, ±24 mA drive, and 4 μA max ICC-making it optimal for industrial and automotive signal conditioning where robustness and efficiency coexist.

FAQ
Is 74LVC1G17GV,125 pin-compatible with other 5-pin Schmitt-trigger buffers?
Yes-it shares the standard SC-74A (SOT753) pinout (n.c./A/GND/Y/VCC) with industry equivalents like SN74LVC1G17DBVR and 74AHC1G17SE-7. Pin 1 is marked with a dot or bevel; no adapter or redesign is needed for footprint reuse.
Can 74LVC1G17GV,125 safely interface a 5 V microcontroller output to a 1.8 V FPGA input?
Yes-its inputs tolerate up to 5.5 V regardless of VCC, and its output swings rail-to-rail (0 V to VCC). When powered at 1.8 V, it accepts 5 V inputs and produces 0–1.8 V outputs compatible with 1.8 V I/O standards.
What is the significance of the IOFF feature in practical system design?
IOFF disables the output and blocks current flow when VCC = 0 V-preventing backfeed from live buses into a powered-down subsystem. This eliminates risk of latch-up or damage during hot-swap, partial power cycling, or fault isolation in multi-rail systems.
Does 74LVC1G17GV,125 require external pull-up or pull-down resistors on its input or output?
No-its CMOS input has negligible leakage (<±1 μA), and the output is actively driven high/low. External resistors are unnecessary unless specific bus-keeping or fail-safe biasing is required by system architecture-not by device functionality.
