onsemi NL17SG04DFT2G

Overview

NL17SG04DFT2G from onsemi is a single high-speed CMOS inverter in SC-88A (SOT-453) package, designed for 0.9 V to 3.6 V supply operation, delivering 2.3 ns typical propagation delay at VCC = 3.0 V and CL = 15 pF, with over-voltage tolerant inputs/outputs up to 3.6 V, supporting low-power logic inversion in space-constrained portable and battery-powered systems.

For engineers reviewing the NL17SG04DFT2G datasheet, pinout, applications, or equivalent options, key selection considerations include its ultra-small footprint, partial power-down capability (IOFF), AEC-Q101 qualification, and guaranteed performance across −55°C to +125°C operating temperature range.

Technical Context

The NL17SG04DFT2G implements a single unbuffered inverter gate using advanced CMOS process technology, enabling rail-to-rail input voltage tolerance beyond VCC (up to 3.6 V) while maintaining defined logic states. Its IOFF feature ensures high-impedance outputs during power-down, preventing current backflow in partial-power-down systems.

Propagation delay varies with supply voltage and load capacitance: 3.4 ns max at VCC = 3.0–3.6 V and CL = 15 pF, and 6.7 ns max at VCC = 1.65–1.95 V under same load. Input leakage remains ≤ ±1.0 µA across full temperature range, supporting stable operation in low-current monitoring circuits.

FAQ

What is the minimum supply voltage for reliable operation of the NL17SG04DFT2G?

The NL17SG04DFT2G is fully specified down to 0.9 V VCC across its entire operating temperature range (−55°C to +125°C). At this voltage, it maintains valid logic thresholds and propagation delay performance per Table 2 and Table 4 of the official datasheet. The NL17SG04DFT2G achieves functional operation even below 0.9 V, but timing and noise margins are not guaranteed outside the recommended range.

Does the NL17SG04DFT2G support true tri-state output functionality?

No, the NL17SG04DFT2G does not provide tri-state output control. It is a standard active-drive inverter with push-pull output stage. However, its IOFF feature ensures that when VCC = 0 V, both output FETs are disabled and the Y pin enters a high-impedance state - this supports partial power-down scenarios but is not user-controllable like an OE pin.

Can the NL17SG04DFT2G be used with 5 V input signals?

No - the absolute maximum input voltage rating is +4.3 V, but the device is not designed for 5 V logic compatibility. Inputs above 3.6 V violate the "Inputs/Outputs Over-Voltage Tolerant up to 3.6 V" specification and may cause latch-up or accelerated degradation. For 5 V interfacing, use a level translator or a 5 V-tolerant inverter such as SN74LVC1G04.

What is the thermal resistance (θJA) of the NL17SG04DFT2G in its SC-88A package?

The NL17SG04DFT2G in SC-88A package has a junction-to-ambient thermal resistance (θJA) of 377°C/W, measured per JESD51-7 on an FR4 board with minimum pad spacing and no airflow. This value assumes standard 2-ounce copper traces; actual θJA improves significantly with thermal vias and larger copper pours.

Is the NL17SG04DFT2G pin-compatible with other MiniGate inverters like NL17SG14?

No - the NL17SG04DFT2G (single inverter) uses a 5-pin SC-88A configuration (NC, GND, A, VCC, Y), whereas the NL17SG14 (Schmitt-trigger inverter) uses the same pinout but different internal characteristics. While physically pin-compatible in SC-88A, they are not functionally interchangeable due to differing hysteresis, propagation delay, and input threshold behavior - always validate timing and noise immunity in target application.
