Product details
Overview
74LVC3G17DC-Q100 from Nexperia is a triple non-inverting Schmitt trigger buffer with 5 V tolerant inputs, designed for signal conditioning in automotive mixed-voltage 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 to AEC-Q100 Grade 1 (−40 °C to +125 °C) for under-hood and ADAS sensor interface applications.
For engineers reviewing the 74LVC3G17DC-Q100 datasheet, 74LVC3G17DC-Q100 pinout, 74LVC3G17DC-Q100 application, or 74LVC3G17DC-Q100 equivalent, this device serves as a robust level-translating waveform shaper in noisy automotive environments-particularly where TTL/CMOS interfacing, ESD resilience, and guaranteed hysteresis (min 0.4 V at 3.0 V) are critical selection criteria.
Technical Context
This device implements three independent Schmitt-trigger input buffers with non-inverting logic function, enabling clean digital signal regeneration from slow or noisy waveforms. Its input threshold hysteresis (VH = 0.40–1.90 V depending on VCC) ensures noise immunity up to 1.4 V at 3.0 V supply, while the IOFF circuit actively disables outputs during power-down to prevent backflow current.
It supports bidirectional voltage translation between 3.3 V and 5 V domains via 5.5 V tolerant inputs and rail-to-rail CMOS outputs. The device complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full 1.65–5.5 V supply range and meets AEC-Q100 stress testing for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables operation across legacy 5 V, standard 3.3 V, and low-power 1.8 V systems without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows direct connection to 5 V microcontrollers or sensors while powered from 3.3 V or lower rails. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive multiple CMOS/TTL loads or moderate capacitive traces in ECUs and body control modules. |
| Hysteresis Voltage (VH) | Min 0.40 V at VCC = 3.0 V - Guarantees reliable noise rejection for signals with >200 mV peak-to-peak interference in engine bay environments. |
| Propagation Delay | Max 5.4 ns at VCC = 4.5–5.5 V - Supports signal conditioning up to ~100 MHz edge rates in timing-critical sensor preprocessing stages. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Limits backfeed current during hot-swap or partial system shutdown, protecting upstream drivers. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets automotive board-level ESD requirements per ISO 10605 without external protection diodes. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8-pin, 2.3 mm body width, 0.5 mm lead pitch, pin 1 indicator at lower-left corner below marking "V17".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6 | Input (1A, 2A, 3A) | Three independent Schmitt-trigger inputs; each accepts 0–5.5 V regardless of VCC, enabling mixed-voltage interfacing. |
| 2, 5, 7 | Output (3Y, 2Y, 1Y) | Non-inverting buffered outputs; rail-to-rail CMOS swing with ±24 mA drive capability at 3.0 V. |
| 4 | GND | Ground reference for all I/O and internal circuitry; must be low-impedance for stable hysteresis and noise immunity. |
| 8 | VCC | Primary supply rail (1.65–5.5 V); powers internal logic and enables IOFF behavior when driven to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation in automotive powertrain and chassis modules with zero derating. |
| IOFF partial power-down mode | Automatically disables outputs when VCC = 0 V, eliminating destructive back-current paths during system sleep or fault isolation. |
| Wide hysteresis window (up to 1.9 V) | Ensures clean switching even with high-amplitude EMI (e.g., alternator ripple, ignition noise) in 12 V vehicle networks. |
| JEDEC-compliant multi-voltage support | Meets JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) for seamless integration across voltage domains. |
| Low ICC supply current | Max 4 μA at VCC = 1.65–5.5 V - minimizes quiescent power in always-on vehicle subsystems like door modules and occupancy sensors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G17MDCKREP | TI's enhanced-product version; same pinout and function but rated for −55 °C to +125 °C with extended screening and lot traceability. | Targeted at military/aerospace and high-reliability industrial control-not automotive-qualified. | Select only if extended temperature range or DLA-qualified sourcing is required; not AEC-Q100 certified. |
| 74LVC3G17GW-Q100 | Nexperia's SC-88 (SOT363) variant: identical electrical specs but 6-pin package housing only two gates (not three). | Lacks third buffer channel; unsuitable for designs requiring all three Schmitt triggers in one footprint. | Use only for dual-channel applications where space constraints preclude VSSOP8; verify gate count sufficiency. |
Compared with SN74LVC3G17MDCKREP, the 74LVC3G17DC-Q100 offers automotive qualification and optimized cost for volume ECU production; versus 74LVC3G17GW-Q100, it delivers full triple-buffer functionality in a compact 8-pin VSSOP package essential for space-constrained ADAS modules.

FAQ
Is the 74LVC3G17DC-Q100 pin-compatible with standard 74LVC3G17 variants?
Yes-it shares identical pinout (SOT765-1 VSSOP8) and logic function with non-automotive 74LVC3G17 variants such as 74LVC3G17DC, but adds AEC-Q100 qualification, extended temperature range (−40 °C to +125 °C), and tightened parametric limits for automotive use. No layout changes are needed for drop-in replacement in qualified designs.
What is the maximum capacitive load this device can drive while maintaining specified propagation delay?
The datasheet specifies dynamic characteristics with 30–50 pF load capacitance (Table 11). At VCC = 3.0 V and CL = 50 pF, tpd remains ≤7.1 ns. Driving >100 pF will increase delay nonlinearly and may degrade edge monotonicity; for >75 pF loads, add series termination or verify timing margins in final layout simulation.
Does the IOFF feature require external pull-up/down resistors on outputs during power-down?
No-IOFF actively disables the output FETs when VCC = 0 V, presenting high-impedance state without external biasing. However, if outputs connect to active-bus systems (e.g., I²C), external weak pull-ups may still be needed for bus integrity, but these do not interact with IOFF operation.
Can this device translate 5 V inputs to 1.8 V logic levels?
No-it accepts 5 V inputs while powered from 1.65–5.5 V, but outputs swing rail-to-rail relative to VCC. To generate 1.8 V logic levels, VCC must be set to 1.8 V; the output will then be 0–1.8 V. Input tolerance does not imply output level shifting-only input overvoltage resilience.
