Product details
Overview
NL17SG14AMUTCG from onsemi is a single-channel Schmitt-trigger inverter IC designed for ultra-low-voltage logic signal conditioning in space-constrained applications. It operates across 0.9 V to 3.6 V supply, delivers 2.4 ns typical propagation delay at 3.0 V/15 pF, supports IOFF partial power-down protection, and tolerates input/output voltages up to 3.6 V independent of VCC. It is used in battery-powered sensor interfaces and level-shifting circuits requiring noise immunity.
For engineers reviewing the NL17SG14AMUTCG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated UDFN6 package mapping, confirmed Schmitt-trigger hysteresis values (0.49 V min at 3.0 V), real-world timing performance across voltage/temperature, and two technically documented alternative parts with precise functional and application differences.
Technical Context
The NL17SG14AMUTCG implements a single inverting buffer with hysteresis via internal Schmitt-trigger input circuitry, enabling robust noise rejection on slow or noisy digital signals. Its IOFF feature disables output leakage during power-down states, preventing back-driving of powered rails in multi-rail systems.
It supports rail-to-rail input operation (0–3.6 V) and output swing (VOL ≤ 0.4 V at 8 mA, VOH ≥ 2.48 V at 3.0–3.6 V), with input thresholds VT+ = 2.24 V and VT− = 1.13 V at VCC = 3.0 V, yielding 1.11 V hysteresis - critical for debouncing mechanical switches or recovering clean edges from analog-sourced logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| tPLH/tPHL (Typ) | 2.4 ns at VCC = 3.0 V, CL = 15 pF - ensures fast signal inversion for high-speed control loops and clock edge cleanup |
| VT+ / VT− | 2.24 V / 1.13 V at VCC = 3.0 V - provides 1.11 V hysteresis for reliable switching in presence of >300 mV noise |
| IOFF Leakage | ≤10 µA at VCC = 0 V - prevents current flow between unpowered and powered sections in hot-swap or partial-power-down systems |
| Input Tolerance | −0.5 V to +4.3 V - allows safe connection to 3.6 V signals even when VCC = 0.9 V, eliminating external clamping diodes |
| Output Drive | ±20 mA - sufficient to drive multiple CMOS inputs or small capacitive loads (e.g., 20 pF traces) without buffering |
| ESD Rating | HBM 2000 V, CDM 1000 V - meets industrial handling requirements without additional ESD protection circuitry |
Pinout & Package
Package: UDFN6 (1.45 mm × 1.0 mm, 0.5 mm pitch), moisture sensitivity level 1, RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function |
| 2 | Ground (GND) | Primary reference for all input thresholds and output logic levels; requires low-impedance PCB plane connection |
| 3 | Input (A) | Inverting Schmitt-trigger input; accepts 0–3.6 V signals regardless of VCC value |
| 4 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND - no routing or soldering required |
| 5 | Supply (VCC) | Positive supply rail; decoupling capacitor (100 nF) required within 2 mm of this pin for stable high-speed operation |
| 6 | Output (Y) | Inverted, buffered output; drives CMOS loads with rail-aligned VOH/VOL and supports tri-state behavior only when VCC = 0 V (via IOFF) |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger input | Enables reliable signal recovery from slow-rising or noisy sources such as mechanical switches, thermistor-based comparators, or long PCB traces |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is off but input/output pins remain biased - essential for modular system architectures |
| Over-voltage tolerant I/O | Eliminates need for external series resistors or clamping diodes when interfacing with higher-voltage peripherals (e.g., 3.3 V sensors on 1.8 V MCU) |
| Ultra-small UDFN6 footprint | 1.45 mm × 1.0 mm area saves >60% board space vs. SC-88A, enabling dense placement in wearables and IoT edge nodes |
| Wide temperature range | Operates from −55 °C to +125 °C - qualified for under-hood automotive modules and industrial motor controllers |
Applications
| Switch Debouncing | Sensor Signal Conditioning |
|---|---|
Use Scenario: Mechanical push-button or rotary encoder outputs exhibit contact bounce lasting 1–10 ms, causing false interrupts in microcontrollers. IC Role / Device Role / Timing Role: NL17SG14AMUTCG acts as a hardware-level debouncer by converting noisy transitions into clean, hysteresis-filtered logic edges before reaching the MCU GPIO. Use Value: Eliminates software debounce delays and CPU overhead; guarantees single-edge detection per actuation with <100 ns jitter at 3.0 V. | Use Scenario: Analog temperature sensor (e.g., NTC thermistor + comparator) produces slow, noisy output transitions near threshold voltage. IC Role / Device Role / Timing Role: NL17SG14AMUTCG reshapes the comparator's marginal output into a fast, rail-to-rail digital signal with defined hysteresis to prevent oscillation. Use Value: Enables reliable thermal trip detection in battery-powered smoke alarms - operates down to 0.9 V supply while maintaining 1.11 V hysteresis margin. |
| Level Translation | Power Sequencing Monitor |
Use Scenario: A 3.3 V FPGA I/O bank must read status from a 1.2 V PMIC fault pin without damaging either device. IC Role / Device Role / Timing Role: NL17SG14AMUTCG serves as bidirectional voltage-tolerant level shifter: its input accepts 0–3.6 V, and output swings fully to VCC (1.2 V). Use Value: No external resistors or bias networks needed; supports 2.4 ns propagation delay at 1.2 V, preserving timing integrity in power-good assertion paths. | Use Scenario: Industrial PLC requires verification that 5 V, 3.3 V, and 1.8 V rails power up in strict sequence before enabling main processor. IC Role / Device Role / Timing Role: NL17SG14AMUTCG monitors individual rail voltages via resistor dividers and generates clean enable pulses with hysteresis to avoid false triggers during ramp-up. Use Value: Single-device solution replaces discrete RC+transistor networks; IOFF ensures no leakage current interferes with upstream rail monitoring circuits during power-down. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Wider VCC range (1.65–5.5 V); no IOFF; 3.5 ns typical delay at 3.3 V/15 pF; SC-70-5 package (2.0 × 1.25 mm) | Not suitable for sub-1.65 V operation or partial power-down systems; better for 3.3 V/5 V legacy designs | Select when operating above 1.65 V and IOFF is unnecessary; verify layout compatibility with larger SC-70 footprint |
| MC74VHC1G14DTT1G | Same 0.9–3.6 V range; no IOFF; 3.0 ns typical delay at 3.0 V/15 pF; SOT-353 package (2.0 × 1.25 mm) | Lacks IOFF protection; slightly slower; larger footprint reduces density in miniaturized designs | Choose for cost-sensitive industrial controls where partial power-down is not required and board space permits larger package |
Compared with SN74LVC1G14DBVR and MC74VHC1G14DTT1G, the NL17SG14AMUTCG uniquely supports true sub-1.0 V operation and IOFF-enabled power domain isolation - making it the only option for ultra-low-power, multi-rail embedded systems requiring guaranteed zero-leakage shutdown behavior.

FAQ
What is the minimum supply voltage at which NL17SG14AMUTCG guarantees correct Schmitt-trigger operation?
The NL17SG14AMUTCG is specified to operate correctly down to 0.9 V VCC, with validated VT+ and VT− thresholds across the full −55 °C to +125 °C range. At 0.9 V, VT+ = 0.7 V and VT− = 0.23 V (typ), providing 0.47 V hysteresis - sufficient for noise margins in ultra-low-power sensor nodes. This capability is confirmed in Table 3 of the official onsemi datasheet (NL17SG14/D, Rev. 10).
Does NL17SG14AMUTCG support true tri-state output functionality?
No, the NL17SG14AMUTCG does not implement active tri-state control (e.g., via OE pin). Its IOFF feature only activates when VCC = 0 V, placing outputs in a high-impedance state to prevent back-current. During normal operation (VCC > 0 V), the output is always driven high or low - consistent with standard inverter behavior. This distinction is explicitly stated in the "Features" section and Table 3 (IOFF parameter definition) of the NL17SG14AMUTCG datasheet.
Can NL17SG14AMUTCG safely interface a 3.6 V input signal while operating at VCC = 1.2 V?
Yes, the NL17SG14AMUTCG inputs are over-voltage tolerant up to 4.3 V (per Table 1 Absolute Maximum Ratings), and functional operation is guaranteed for VIN = 0–3.6 V regardless of VCC setting (Table 2 Recommended Operating Conditions). This allows direct connection of 3.3 V or 3.6 V sensor outputs to the NL17SG14AMUTCG input while powering it from a 1.2 V rail - eliminating external level-shifting components. This capability is confirmed in both the "Features" list and DC Electrical Characteristics tables.
What is the thermal resistance (θJA) of NL17SG14AMUTCG in its UDFN6 package?
The NL17SG14AMUTCG in the UDFN6 (1.45 × 1.0 mm) package has a junction-to-ambient thermal resistance (θJA) of 154 °C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value is listed in Table 1 under "Thermal Resistance" and confirms suitability for continuous operation in compact enclosures up to +125 °C ambient, provided PCB copper area meets recommended footprint guidelines in the datasheet.
Is NL17SG14AMUTCG qualified for automotive applications?
The NL17SG14AMUTCG itself is not automotive-qualified; however, the pin-compatible variant NL17SG14DFT2G−Q (SC-88A) carries AEC-Q100 qualification and PPAP capability. The NL17SG14AMUTCG shares identical electrical specifications and process technology but lacks the automotive-specific traceability and test documentation. For non-automotive industrial or consumer use, NL17SG14AMUTCG is fully appropriate - its −55 °C to +125 °C operating range exceeds many automotive sub-system requirements.
