Product details
Overview
74LVC1G17GW,125 from Nexperia is a single Schmitt-trigger buffer IC designed for signal conditioning and noise immunity 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 automotive-grade temperature range (–40 °C to +125 °C) in TSSOP5 (SOT353-1) package.
For engineers reviewing the 74LVC1G17GW,125 datasheet, 74LVC1G17GW,125 pinout, 74LVC1G17GW,125 application, or 74LVC1G17GW,125 equivalent, this device serves as a robust level-translating buffer in I²C bus conditioning, push-button debouncing, and sensor interface circuits where hysteresis and rail-to-rail compatibility are critical.
Technical Context
The 74LVC1G17GW implements a CMOS-based Schmitt-trigger transfer function with asymmetric hysteresis (e.g., VT+ = 1.29 V / VT− = 0.88 V at VCC = 3.0 V), enabling reliable noise rejection on slow or noisy input edges. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
It supports unlimited input rise/fall times and interfaces directly with TTL logic levels while maintaining full JEDEC compliance across four voltage domains (JESD8-7, JESD8-5, JESD8C, JESD36). Input clamping and ESD protection (HBM >2000 V, CDM >1000 V) ensure robustness in industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.65 V to 5.5 V - Enables direct operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. |
| Input Voltage Range | 0 V to 5.5 V - Allows safe interfacing with 5 V signals even when powered at 1.65 V, supporting mixed-voltage translation. |
| Hysteresis Voltage (VH) | 0.41 V to 0.88 V (VCC = 1.8 V to 5.5 V) - Provides stable switching thresholds that reject noise spikes ≤400 mV peak-to-peak. |
| Output Drive | ±24 mA at VCC = 3.0 V - Sufficient to drive 15 pF loads with <7 ns propagation delay, suitable for fan-out to multiple CMOS inputs. |
| IOFF Leakage | ±2 μA max at VCC = 0 V - Prevents damaging back-current flow during hot-swap or partial power-down system states. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive, industrial control, and extended-temperature embedded applications. |
| Propagation Delay | 0.7 ns (min) to 7.0 ns (max) at VCC = 3.0 V - Ensures deterministic timing in high-speed signal conditioning paths. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed padless construction, rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| n.c. | No-connect terminal | Physically present but internally unconnected; must remain floating or grounded per layout best practice - no routing required. |
| A | Data input | Schmitt-triggered input accepting 0–5.5 V; hysteresis eliminates chatter on slow-rising sensor or mechanical switch signals. |
| GND | Ground reference | 0 V return path for all internal circuitry and output current; requires low-impedance PCB connection to minimize noise coupling. |
| Y | Data output | Inverting buffer output (non-inverting logic function); drives CMOS/TTL loads with rail-to-rail swing and IOFF disable capability. |
| VCC | Supply voltage | Primary power rail (1.65–5.5 V); powers internal logic and output stage; decoupling capacitor (100 nF) recommended within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | Operates from 1.65 V to 5.5 V - eliminates need for separate voltage translators in multi-rail systems. |
| Overvoltage-tolerant inputs | Withstands 5.5 V inputs regardless of VCC - enables safe 5 V signal injection into 1.8 V or 3.3 V domains. |
| IOFF partial power-down | Outputs disabled with leakage <±2 μA when VCC = 0 V - prevents backfeed in hot-plug or battery-backed subsystems. |
| High noise immunity | Hysteresis ≥0.4 V across full VCC range - rejects EMI and contact bounce in industrial sensor and switch interfaces. |
| JEDEC-compliant I/O | Meets JESD8-7/5/8C/36 standards - guarantees interoperability with legacy and next-generation logic families. |
Applications
| Industrial Push-Button Interface | I²C Bus Signal Conditioning |
|---|---|
Use Scenario: Mechanical push-button connected to microcontroller GPIO with long traces in factory automation panel. IC Role / Device Role / Timing Role: Schmitt-trigger buffer isolates MCU input from contact bounce and EMI-induced glitches. Use Value: Eliminates software debouncing overhead and ensures single, clean edge detection per press - reducing firmware complexity and interrupt latency. | Use Scenario: I²C SDA/SCL lines routed across noisy motor-drive PCB with >10 cm trace length. IC Role / Device Role / Timing Role: Non-inverting buffer restores signal integrity and strengthens slew rate on bidirectional open-drain lines. Use Value: Prevents false ACK/NACK due to ringing or undershoot, enabling reliable 400 kHz Fast-mode operation in electrically hostile environments. |
| Automotive Sensor Signal Amplification | Low-Power Wearable Device Input Stage |
Use Scenario: Analog output from temperature/humidity sensor feeding into ADC input of automotive body controller. IC Role / Device Role / Timing Role: Level-shifting buffer converts noisy analog comparator output to clean digital enable signal for ADC sampling trigger. Use Value: Hysteresis suppresses thermal noise near threshold crossings, ensuring accurate event-triggered sampling without missed or spurious conversions. | Use Scenario: Capacitive touch sensor node in battery-powered fitness tracker with ultra-low sleep current budget. IC Role / Device Role / Timing Role: Input conditioner for wake-up interrupt line, activated only on valid finger proximity events. Use Value: IOFF mode draws <2 μA during MCU sleep - extends battery life by minimizing false wake-ups from leakage or RF coupling. |
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 IOFF not specified; HBM ESD = 2000 V (same). | Lacks guaranteed IOFF behavior - unsuitable for partial-power-down systems requiring back-current blocking. | Select only if system remains fully powered during standby and board space allows SOT-23 footprint. |
| 74AUP1G17GW,125 | Nexperia AUP variant in same TSSOP5 package; lower ICC (0.9 μA typ), wider hysteresis (VH = 0.5–1.0 V), but reduced drive (±4 mA @ 3.0 V). | Better for ultra-low-power always-on sensing; insufficient for driving >2 CMOS loads or terminating stubs. | Prefer when sub-μA quiescent current is mandatory and output loading is light (e.g., single MCU input). |
Compared with SN74LVC1G17DBVR and 74AUP1G17GW,125, the 74LVC1G17GW,125 uniquely balances robust 24 mA drive, guaranteed IOFF, and automotive temperature rating - making it optimal for mixed-voltage industrial and automotive signal conditioning where reliability under partial power-down is non-negotiable.

FAQ
Can the 74LVC1G17GW,125 be used as a level shifter between 1.8 V and 5 V domains?
Yes - its overvoltage-tolerant inputs accept 0–5.5 V regardless of VCC, and output swings rail-to-rail. When powered at 1.8 V, it safely buffers 5 V inputs and produces 1.8 V CMOS-compatible outputs, satisfying bidirectional level-shifting requirements without external components.
Does the 74LVC1G17GW,125 support hot-swap insertion while other rails remain active?
Yes - the IOFF circuit ensures outputs are high-impedance and leakage is limited to ±2 μA when VCC = 0 V, preventing back-current flow into powered downstream logic. This enables safe insertion into live backplanes or modular subsystems without disrupting adjacent circuitry.
What is the minimum load capacitance the 74LVC1G17GW,125 can drive while maintaining specified propagation delay?
The datasheet specifies tpd performance with CL = 30–50 pF loads. At CL = 15 pF, propagation delay improves to ≤5.0 ns (VCC = 3.0 V), verified via typical characterization curves. Driving lower capacitance is permissible and enhances speed, provided trace impedance and termination avoid reflections.
How does the Schmitt-trigger hysteresis vary with supply voltage?
Hysteresis (VH = VT+ − VT−) scales linearly with VCC: 0.41 V at 1.8 V, 0.43 V at 2.3 V, 0.47 V at 3.0 V, 0.52 V at 4.5 V, and 0.53 V at 5.5 V. This ensures consistent noise margin percentage (~25% of VCC) across the full operating range.
