Product details
Overview
NL17SG17DFT2G from onsemi is a single-channel Schmitt trigger buffer IC designed for signal conditioning and noise-immune digital interface applications. It operates across 0.9 V to 3.6 V supply, delivers 3.7 ns typical propagation delay at 3.0 V/15 pF, features 3.6 V overvoltage-tolerant inputs, and supports partial power-down via IOFF. It is used in low-power sensor interface and battery-powered microcontroller I/O expansion circuits.
For engineers reviewing the NL17SG17DFT2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range compatibility, input hysteresis (0.49 V typ at 3.0 V), output drive capability (±8 mA), ultra-small SC-88A package footprint, and IOFF-enabled system-level power sequencing.
Technical Context
The NL17SG17DFT2G implements a CMOS-based Schmitt-trigger input stage with asymmetric threshold voltages (VT+ = 2.24 V, VT− = 1.13 V at VCC = 3.0 V), enabling robust noise rejection in noisy environments. Its output stage provides rail-to-rail swing and supports tri-state operation only when explicitly enabled via external control - though the device itself has no dedicated enable pin, its IOFF behavior activates automatically during power-down.
It uses advanced low-threshold CMOS process technology to achieve sub-1 V minimum operating voltage while maintaining full 3.6 V input tolerance. The input structure includes integrated protection diodes rated for ±20 mA DC current, and the device meets JEDEC JESD78 Class II latch-up immunity (±100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.9 V to 3.6 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| tPD (Typ) | 3.7 ns at VCC = 3.0 V, CL = 15 pF - ensures timing-critical signal routing in high-speed MCU peripheral interfaces. |
| Input Hysteresis | 0.49 V (typ) at VCC = 3.0 V - rejects up to ~16% of supply noise on slow-rising/falling signals like pushbutton or sensor outputs. |
| IOFF Leakage | ≤10.0 µA at TA = −55°C to +125°C - prevents back-driving powered-down sections in mixed-voltage systems. |
| Output Drive | ±8 mA at VCC ≥ 2.7 V - sufficient to directly drive multiple 74LVC inputs or small LED indicators without external buffers. |
| Input Voltage Tolerance | Up to 3.6 V independent of VCC - allows safe connection to higher-voltage sources (e.g., 3.3 V sensors) even when VCC = 1.2 V. |
| ESD Rating | HBM: 2000 V, CDM: 1000 V - exceeds industrial IEC 61000-4-2 Level 2 requirements for board-level robustness. |
Pinout & Package
NL17SG17DFT2G is packaged in SC-88A (Case 419A), a 5-pin, 1.25 mm × 2.0 mm surface-mount package with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-203-DA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC (No Connect) | Internally unconnected; must be left floating or tied to GND for mechanical stability - no electrical function. |
| 2 | A (Input) | Dedicated Schmitt-trigger input with hysteresis; accepts 0–3.6 V regardless of VCC value. |
| 3 | GND | Ground reference for both input thresholds and output logic levels; requires low-inductance PCB connection. |
| 4 | VCC | Positive supply input; powers internal logic and defines VOH/VOL levels; bypass capacitor (100 nF) recommended near pin. |
| 5 | Y (Output) | Inverting buffered output with rail-to-rail swing; drives capacitive loads ≤30 pF within spec; not internally tri-statable. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (0.9–3.6 V) | Supports single-supply operation across ultra-low-power (1.2 V IoT nodes) and standard 3.3 V industrial interfaces. |
| 3.6 V overvoltage-tolerant inputs | Eliminates need for external clamping diodes when interfacing with legacy 3.3 V peripherals in 1.8 V systems. |
| IOFF partial power-down protection | Prevents current flow through A or Y pins when VCC = 0 V, enabling hot-swap and multi-rail sequencing safety. |
| Ultra-small SC-88A footprint | 1.25 mm × 2.0 mm area saves >60% board space vs. SOIC-5; compatible with fine-pitch automated assembly. |
| Pb-free, RoHS-compliant construction | Meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at <30°C/60% RH). |
Applications
| Industrial Sensor Interface | Low-Power Microcontroller I/O Expansion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Wider VCC range (1.65–5.5 V); no IOFF; 3.3 V min VCC vs. NL17SG17DFT2G's 0.9 V; slightly slower tPD (4.5 ns typ). | Requires ≥1.65 V supply; unsuitable for sub-1.2 V systems; lacks power-down isolation for mixed-rail designs. | Select when interfacing exclusively with 3.3 V or 5 V logic and IOFF is not required. |
| TC7SZ17FU,LF | Same 0.9–3.6 V range and SC-88A package; lower hysteresis (0.35 V typ at 3.0 V); higher ICC (1.0 µA max); no MSL1 rating. | Reduced noise immunity margin; less suitable for high-noise industrial environments; shorter floor life handling. | Select for cost-sensitive consumer applications where 0.35 V hysteresis suffices and extended storage is not required. |
Compared with SN74LVC1G17DBVR and TC7SZ17FU,LF, NL17SG17DFT2G uniquely combines sub-1 V operation, 3.6 V OVT inputs, and IOFF - making it the only option for battery-powered, multi-rail systems requiring guaranteed power-down isolation and wide supply flexibility.

FAQ
What is the minimum operating voltage for NL17SG17DFT2G?
The NL17SG17DFT2G operates down to 0.9 V, enabling compatibility with emerging ultra-low-power microcontrollers and energy-harvesting systems. This specification is validated across the full industrial temperature range (−55°C to +125°C) and confirmed in Table 2 of the official onsemi datasheet. At 0.9 V, the device maintains functional Schmitt thresholds and specified propagation delay.
Does NL17SG17DFT2G have a dedicated enable pin?
No, NL17SG17DFT2G does not include a dedicated enable or output control pin. Its output is always active when powered. However, the device features automatic IOFF functionality: when VCC = 0 V, both input and output terminals enter high-impedance state with leakage ≤10 µA, providing passive isolation without external control logic.
Can NL17SG17DFT2G safely interface a 3.3 V sensor output to a 1.2 V microcontroller?
Yes, NL17SG17DFT2G can safely perform this level translation. Its inputs tolerate up to 3.6 V regardless of VCC value, and with VCC = 1.2 V, the output swings rail-to-rail between 0 V and 1.2 V. This eliminates external resistive dividers or active translators while maintaining noise immunity via built-in hysteresis.
What is the thermal resistance (θJA) of NL17SG17DFT2G in SC-88A package?
The thermal resistance θJA for NL17SG17DFT2G in SC-88A (Case 419A) is 377°C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value is critical for estimating junction temperature rise under sustained load and confirms suitability for ambient temperatures up to +125°C with appropriate PCB copper area.
Is NL17SG17DFT2G pin-compatible with other SC-88A logic buffers?
No, NL17SG17DFT2G is not pin-compatible with generic SC-88A logic buffers due to its NC (no-connect) pin at position 1. Most SC-88A logic devices (e.g., SN74LVC1G17) use pin 1 as input. PCB layout must accommodate this unique pin assignment - swapping without redesign risks open-input faults or incorrect signal routing.
