onsemi NL17SGU04AMUTCG

Overview

NL17SGU04AMUTCG from onsemi is an unbuffered CMOS inverter optimized for ultra-low-power, high-speed logic inversion in space-constrained applications. It operates across 0.9 V to 3.6 V supply, delivers 1.9 ns typical propagation delay at 3.0 V/15 pF, tolerates 3.6 V input overvoltage, and supports automotive-grade operation per AEC-Q101. It is used in level-shifting, signal conditioning, and enable/inhibit control paths in portable and automotive electronics.

For engineers reviewing the NL17SGU04AMUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include its unbuffered architecture (low capacitance, no added delay staging), 3.6 V OVT input tolerance enabling mixed-voltage interface, wide V_CC range supporting battery-powered systems, and UDFN6 1.45 × 1.0 mm package with exposed thermal pad for thermal reliability.

Technical Context

The NL17SGU04AMUTCG implements a single-stage CMOS inverter without internal buffering-preserving minimal propagation delay and input-to-output capacitive coupling. Its input structure includes overvoltage-tolerant clamping diodes rated to 3.6 V, allowing safe interfacing with higher-voltage logic domains while powered from sub-1.2 V supplies.

It features rail-to-rail output swing, supports ±20 mA output drive, and maintains specified timing performance across −55°C to +125°C ambient. The device uses standard TTL/CMOS-compatible thresholds (V_IL ≤ 0.2×V_CC, V_IH ≥ 0.8×V_CC) and exhibits low dynamic power via CPD = 4 pF, enabling efficient operation at frequencies up to 10 MHz under light loads.

FAQ

What is the maximum input voltage the NL17SGU04AMUTCG can tolerate regardless of V_CC?

The NL17SGU04AMUTCG supports 3.6 V overvoltage-tolerant (OVT) inputs-meaning it can safely accept input signals up to 3.6 V even when V_CC is as low as 0.9 V. This is confirmed in the datasheet's "Features" section and Table 1 (VIN max = +4.3 V absolute rating, with OVT functionality explicitly defined at 3.6 V). This capability eliminates the need for external clamping diodes in mixed-voltage designs involving the NL17SGU04AMUTCG.

Does the NL17SGU04AMUTCG have a buffered or unbuffered logic structure?

The NL17SGU04AMUTCG uses an unbuffered CMOS inverter structure, as stated in the datasheet title ("Unbuffered Inverter") and confirmed by its low input capacitance (C_IN = 3 pF), absence of internal staging, and propagation delay characteristics. Unlike buffered inverters (e.g., SN74LVC1G04), the NL17SGU04AMUTCG avoids added delay and output loading-making it ideal for timing-critical, low-capacitance signal paths where the NL17SGU04AMUTCG is deployed.

Which package variant does NL17SGU04AMUTCG correspond to, and what are its key mechanical features?

NL17SGU04AMUTCG is the UDFN6 (1.45 × 1.0 mm) variant per onsemi's ordering table (page 6), Case 517AQ. It features six terminals with wettable flanks, a 0.5 mm pitch, and an exposed thermal pad on pin 3. The package supports reflow soldering per J-STD-020, has θ_JA = 154°C/W, and is rated MSL Level 1-enabling robust thermal performance and high-yield assembly in compact NL17SGU04AMUTCG-based designs.

Is the NL17SGU04AMUTCG qualified for automotive applications?

Yes-the NL17SGU04AMUTCG is AEC-Q101 qualified and PPAP capable, as explicitly noted in the datasheet's "Features" section and ordering table footnote (*−Q Suffix… AEC−Q101 Qualified). This qualification covers stress testing for temperature cycling, humidity, ESD, and accelerated life-validating the NL17SGU04AMUTCG for use in automotive body electronics, ADAS sensor interfaces, and powertrain subsystems.

What is the typical propagation delay of the NL17SGU04AMUTCG at 1.8 V supply and 15 pF load?

Per Table 4 (AC Electrical Characteristics), the NL17SGU04AMUTCG exhibits t_PLH/t_PHL = 2.6 ns (typ) at V_CC = 1.65–1.95 V and C_L = 15 pF. Since 1.8 V falls within that range, the typical propagation delay for the NL17SGU04AMUTCG under those conditions is 2.6 ns-enabling reliable sub-4 ns signal inversion in low-voltage portable and wearable systems.
