onsemi NC7SP02P5X

Overview

NC7SP02P5X from onsemi is a single 2-input ultra-low-power (ULP-A) NOR gate in SC-88A package, designed for V_CC = 0.9 V to 3.6 V operation, delivering 2.3 ns typical propagation delay at 3.3 V, ±2.6 mA I_O drive capability, and input/output over-voltage tolerance up to 3.6 V - used in power-constrained logic interfacing in portable IoT sensors and battery-powered microcontroller peripheral control.

For engineers reviewing the NC7SP02P5X datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SC-88A pin mapping, confirmed low-voltage DC/AC specs, and real-world use cases in rail-flexible digital signal conditioning and partial-power-down systems.

Technical Context

The NC7SP02P5X implements complementary CMOS logic with rail-to-rail input voltage support (0–3.6 V) and active-mode output swing within 0.1 V of V_CC or GND. Its IOFF feature enables bidirectional isolation during power-down, preventing back-drive current when V_CC = 0 V.

Propagation delay scales predictably with supply voltage (e.g., 7.0 ns max at 2.3–2.7 V, 6.9 ns max at 3.0–3.6 V under 10 pF load), and input leakage remains ≤±0.5 µA across −40°C to +85°C, supporting stable operation in thermally variable embedded environments.

Key Specifications

Pinout & Package

NC7SP02P5X is packaged in SC-88A (SOT-353), a 5-pin, 1.45 mm × 1.0 mm surface-mount package with 0.65 mm lead pitch and Q4 pin 1 orientation per tape-and-reel shipping standard.

FAQ

What is the minimum operating voltage for NC7SP02P5X?

The NC7SP02P5X operates down to 0.9 V V_CC, as specified in the Recommended Operating Conditions table. At this voltage, it maintains functional logic behavior with VIH/VIL thresholds scaled to 0.5 V and 0.5 V respectively, and delivers measurable propagation delay (40.2 ns typical at 10 pF). This makes NC7SP02P5X suitable for energy-harvesting circuits and single-cell LiFePO₄ systems where supply rails dip near 1.0 V.

Does NC7SP02P5X support partial power-down mode?

Yes, NC7SP02P5X supports partial power-down via its IOFF feature. When V_CC = 0 V, the inputs and outputs enter high-impedance state with leakage ≤0.5 µA, preventing current backflow between powered and unpowered sections. This behavior is explicitly characterized in the DC Electrical Characteristics table under IOFF parameter and applies to both SC-88A and MicroPak variants of NC7SP02P5X.

Is NC7SP02P5X pin-compatible with other TinyLogic NOR gates?

No, NC7SP02P5X is not pin-compatible with other TinyLogic NOR gates such as NC7SZ02 or NC7WZ02. It uses a dedicated 5-pin SC-88A configuration (A, B, GND, Y, V_CC) with no enable or OE pin. The NC7SP02P5X pinout differs from NC7SZ02 (SOT-23-5, same pin count but different assignment) and NC7WZ02 (dual gate, 6-pin SC-70), requiring unique PCB layout.

What is the maximum capacitive load NC7SP02P5X can drive reliably?

The NC7SP02P5X is characterized up to 30 pF load capacitance in AC Electrical Characteristics, with propagation delay increasing predictably (e.g., 8.9 ns max at 3.0–3.6 V, CL = 30 pF). For reliable signal integrity, keep total load (including trace and probe capacitance) ≤30 pF. Driving >50 pF may cause excessive rise/fall times or logic threshold uncertainty, especially below 1.8 V V_CC.

Can NC7SP02P5X be used with 5 V-tolerant microcontrollers?

Yes - NC7SP02P5X inputs are over-voltage tolerant up to 3.6 V regardless of V_CC, allowing safe connection to 3.3 V outputs of 5 V-tolerant MCUs (e.g., STM32F0/F3 series). However, its outputs swing only to V_CC − 0.1 V (max), so driving a 5 V logic input directly is not recommended unless the receiving device specifies VIH ≤ V_CC − 0.1 V. For 5 V interfaces, add a pull-up or level shifter.
