Product details
Overview
NL17SZ17DBVT1G from onsemi is a single non-inverting Schmitt trigger buffer in SC-74A (SOT-23-5) package, operating from 1.65 V to 5.5 V supply, delivering 3.7 ns typical propagation delay at 5 V, ±24 mA drive capability at 3.0 V, and input hysteresis up to 1.7 V - used for noise-immune signal conditioning in industrial sensor interfaces and low-voltage logic level translation.
For engineers reviewing the NL17SZ17DBVT1G datasheet, pinout, applications, or equivalent options, this page provides verified pin assignments, real-world timing behavior under 15 pF load, Schmitt threshold values across voltage rails, IOFF partial power-down support, and AEC-Q100-qualified alternatives for automotive-grade designs.
Technical Context
The NL17SZ17DBVT1G implements a single-channel non-inverting buffer with built-in Schmitt-trigger input hysteresis, enabling robust noise rejection on slow or noisy digital signals. Its input thresholds (VT+ = 1.9–3.6 V, VT− = 0.6–1.9 V at VCC = 3.0–5.5 V) provide ≥0.4 V hysteresis across full supply range.
It supports tri-state-compatible operation via IOFF circuitry that disables I/O leakage when VCC = 0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V independent of supply rail - allowing safe interfacing between mixed-voltage domains such as 1.8 V logic driving 3.3 V or 5 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| tPD (typ) | 3.7 ns at VCC = 5 V, RL = 1 MΩ, CL = 15 pF - ensures minimal delay in high-speed clock/data buffering applications. |
| IOH/IOL | ±24 mA at VCC = 3.0 V - drives standard TTL loads or multiple CMOS inputs without external buffers. |
| Input Hysteresis | 0.7 V (min) to 1.7 V (max) - rejects noise spikes up to ±850 mV on input lines in industrial environments. |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents back-powering and signal contention during partial power-down sequences. |
| ESD Rating | HBM ±2000 V, CDM ±1000 V - meets IEC 61000-4-2 Level 3 requirements for board-level ESD immunity. |
| Operating Temp | −55 °C to +125 °C - qualified for extended temperature operation in automotive engine control and industrial PLC modules. |
Pinout & Package
Package: SC-74A (SOT-23-5), 3.00 mm × 1.50 mm × 0.95 mm body, 0.95 mm pitch, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No-connect terminal | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function. |
| 2 (A) | Input signal | Schmitt-triggered non-inverting input; accepts DC voltages from 0 V to 5.5 V regardless of VCC value. |
| 3 (GND) | Ground reference | Primary return path for supply current and output sink current; requires low-impedance PCB connection. |
| 4 (Y) | Output signal | Non-inverted buffered output with rail-to-rail swing; capable of sourcing/sinking ±24 mA at 3.0 V. |
| 5 (VCC) | Positive supply | Power rail input; decoupling capacitor (0.1 µF ceramic) required within 2 mm of pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Provides 0.4–1.7 V hysteresis to reject noise on slow-rising signals like mechanical switch debouncing or sensor outputs. |
| IOFF partial power-down | Enables hot-plug compatibility and system-level power sequencing by blocking I/O leakage when VCC = 0 V. |
| Overvoltage-tolerant I/O | Accepts input/output signals up to 5.5 V even when VCC = 1.65 V - eliminates need for external clamping diodes. |
| Low dynamic power | CPD = 9–11 pF enables <1 µW no-load power at 1 MHz and 3.3 V - suitable for battery-powered IoT edge nodes. |
| AEC-Q100 qualification | Qualified to Grade 1 (−40 °C to +125 °C) with PPAP documentation support - approved for automotive infotainment and ADAS subsystems. |
Applications
| Industrial Sensor Interface | Low-Voltage Logic Translation |
|---|---|
|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, RTD, or Hall-effect switches) before ADC sampling or microcontroller GPIO capture. IC Role / Device Role / Timing Role: Schmitt-trigger buffer cleans slow, noisy edges and provides clean digital transitions to MCU interrupt pins. Use Value: Eliminates software debouncing overhead and prevents false triggering due to EMI-induced glitches on long PCB traces. |
Use Scenario: Interfacing 1.8 V FPGA I/O banks with 3.3 V peripheral UARTs or SPI flash memory. IC Role / Device Role / Timing Role: Non-inverting level shifter with rail-to-rail output swing and sub-4 ns delay preserves timing margins. Use Value: Enables bidirectional signal integrity without direction-control logic or external resistors - reduces BOM count by one component. |
| Automotive Body Control Module | Consumer Wearable Power Sequencing |
|
Use Scenario: Debouncing door latch or seatbelt switch inputs in BCMs operating across −40 °C to +125 °C ambient. IC Role / Device Role / Timing Role: AEC-Q100-qualified Schmitt buffer with IOFF ensures safe isolation during sleep/wake transitions. Use Value: Meets ISO 16750-2 pulse test requirements and avoids wake-up false triggers caused by load-dump transients. |
Use Scenario: Enabling/disabling power rails in compact wearables using microcontroller GPIO with weak drive strength. IC Role / Device Role / Timing Role: Buffer amplifies MCU output to reliably drive MOSFET gate drivers or PMIC enable inputs. Use Value: Delivers 24 mA sink/source at 1.8 V supply - sufficient to charge/discharge gate capacitance faster than MCU GPIO alone. |
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 | Same SC-70-5 (SC-74A) package; lower hysteresis (0.2 V typ), no IOFF, max VCC = 5.5 V. | Lacks partial power-down protection; unsuitable for hot-swap or multi-rail sequencing where VCC may be off. | Select when cost sensitivity outweighs IOFF requirement and ambient temperature stays ≤85 °C. |
| MC74VHC1G17DTT1G | Same SC-74A package; higher ICC (10 µA max vs. 1 µA), no AEC-Q100 qualification, VHCT-compatible thresholds. | Not automotive-qualified; hysteresis optimized for 3.3 V/5 V only - less effective below 2.5 V. | Prefer for legacy 5 V systems requiring tighter VIH/VIL matching to older TTL families. |
Compared with SN74LVC1G17DBVR and MC74VHC1G17DTT1G, the NL17SZ17DBVT1G uniquely combines AEC-Q100 qualification, IOFF-enabled partial power-down, and wide-voltage hysteresis (down to 1.65 V), making it the only choice for automotive-grade, mixed-supply, or ultra-low-power industrial designs requiring guaranteed noise immunity.

FAQ
What is the pin 1 marking orientation for NL17SZ17DBVT1G in SC-74A tape-and-reel packaging?
The NL17SZ17DBVT1G uses SC-74A (SOT-23-5) packaging with pin 1 identified by a dot or notch on the top surface, located adjacent to the leadframe tab side. Per onsemi's ordering information, the marking code "AM" appears on the device body, and pin 1 orientation follows Q4 quadrant placement in tape-and-reel - confirmed in the device's mechanical drawing CASE 318BQ.
Does NL17SZ17DBVT1G support true tri-state operation?
No, the NL17SZ17DBVT1G does not feature an output-enable (OE) pin or internal tri-state logic. It operates exclusively as a non-inverting buffer. However, its IOFF circuitry provides partial power-down protection: when VCC = 0 V, both input and output terminals enter high-impedance mode with ≤10 µA leakage - functionally isolating the device without requiring external OE control.
What is the minimum input rise/fall time supported by NL17SZ17DBVT1G across its operating voltage range?
The NL17SZ17DBVT1G imposes no minimum input edge rate - the recommended operating conditions specify "No Limit" for tr/tf across all VCC ranges (1.65–1.95 V, 2.3–2.7 V, 3.0–3.6 V, and 4.5–5.5 V). This allows reliable operation with very slow-switching signals such as thermistor-based comparators or mechanical switch closures, leveraging its Schmitt-trigger hysteresis for clean output transitions.
Can NL17SZ17DBVT1G be used to interface a 5 V microcontroller with a 1.8 V FPGA input?
Yes - the NL17SZ17DBVT1G's overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC level. Set VCC = 1.8 V to match the FPGA's I/O voltage, connect the 5 V MCU output directly to pin 2 (A), and take the buffered 1.8 V-compatible output from pin 4 (Y). No external resistors or level-shifting components are needed, preserving signal integrity and timing margin.
Is NL17SZ17DBVT1G pin-compatible with other TinyLogic® Schmitt buffers in SC-74A packages?
Yes - the NL17SZ17DBVT1G shares identical SC-74A pinout (pin 1 = NC, pin 2 = A, pin 3 = GND, pin 4 = Y, pin 5 = VCC) with other onsemi TinyLogic® Schmitt buffers including NL17SZ14 (inverter) and NL17SZ74 (D-flip-flop), enabling drop-in replacement in existing layouts where functional change is acceptable and PCB footprint reuse is desired.
