onsemi NL17SG02AMUTCG

Overview

NL17SG02AMUTCG from onsemi is a single 2-input NOR gate logic IC in ultra-small UDFN6 (1.45 × 1.0 mm) package, operating across 0.9 V to 3.6 V supply, delivering 2.4 ns typical propagation delay at 3.0 V/15 pF, with 4.6 V overvoltage-tolerant inputs and ±20 mA output drive-used for level-shifting and noise-immune signal conditioning in space-constrained portable power management circuits.

For engineers reviewing the NL17SG02AMUTCG datasheet, pinout, applications, or equivalent options, key selection criteria include its wide V_CC range, OVT input robustness, low ICC quiescent current (0.5 µA max), and compatibility with 1.8 V/2.5 V/3.3 V logic families in battery-powered IoT sensor nodes and wearables.

Technical Context

The NL17SG02AMUTCG implements complementary CMOS transistor pairs to realize a two-input NOR function with rail-to-rail output swing and input thresholds scaled to V_CC (VIH = 0.65×V_CC, VIL = 0.35×V_CC at 1.4–1.6 V). Its input structure includes integrated clamping diodes enabling 4.6 V overvoltage tolerance independent of V_CC.

Propagation delay varies predictably with supply voltage and load capacitance: t_PD = 3.9 ns (max) at 2.3–2.7 V/30 pF and 3.7 ns (max) at 3.0–3.6 V/15 pF. Input capacitance is fixed at 3 pF, and power dissipation capacitance CPD is 4 pF, supporting accurate dynamic power estimation via PD = CPD·V_CC²·f.

FAQ

What is the maximum input voltage rating for NL17SG02AMUTCG?

The NL17SG02AMUTCG supports DC input voltages up to +4.6 V regardless of V_CC level, thanks to integrated overvoltage-tolerant (OVT) input structures. This specification is validated per JEDEC JESD78 latch-up testing and allows direct connection to 5 V analog sensors or legacy digital buses without external protection components. The absolute maximum rating remains −0.5 V to +4.6 V, and operation beyond this risks permanent damage.

Does NL17SG02AMUTCG require external pull-up or pull-down resistors on its inputs?

No, the NL17SG02AMUTCG does not require external pull-up or pull-down resistors on IN A or IN B because its CMOS inputs exhibit negligible leakage (I_IN ≤ 1.0 µA) and defined VIH/VIL thresholds across the full 0.9–3.6 V V_CC range. However, floating inputs must be avoided in practice-unused inputs should be tied to V_CC or GND to prevent metastability and increased ICC. The NC pin (Pin 4) must remain unconnected.

What is the thermal performance of NL17SG02AMUTCG in its UDFN6 package?

The NL17SG02AMUTCG in UDFN6 (1.45 × 1.0 mm, Case 517AQ) has a junction-to-ambient thermal resistance (θ_JA) of 220°C/W on a standard 2-layer FR4 board with minimum copper pads, per onsemi's characterization. With proper PCB thermal vias under the exposed die pad (not present in this variant), θ_JA can improve to ~160°C/W. Maximum junction temperature is +150°C, and derating begins above +85°C ambient for continuous 20 mA output loading.

Can NL17SG02AMUTCG drive a 15 pF load at 3.0 V while maintaining 2.4 ns typical propagation delay?

Yes-the NL17SG02AMUTCG datasheet explicitly specifies t_PLH/t_PHL = 2.4 ns (typical) under conditions of V_CC = 3.0 V, C_L = 15 pF, and R_L = 1 MΩ. This value is measured using 3.0 ns input rise/fall times and represents average delay across process/voltage/temperature corners. For production designs, the maximum delay is 3.1 ns (−55°C to +125°C), which must be used in timing closure analysis.

Is NL17SG02AMUTCG pin-compatible with other variants in the NL17SG02 family?

No-NL17SG02AMUTCG uses a 6-pin UDFN6 package (1.45 × 1.0 mm) with Pin 4 designated NC, whereas NL17SG02P5T5G (SOT-953) and NL17SG02DFT2G (SC-88A) are 5-pin packages with no NC pin. The pin functions (V_CC, GND, IN A, IN B, OUT Y) align across variants, but physical layout, solder mask clearance, and thermal pad presence differ significantly. Direct PCB replacement requires redesign.
