NC7S00M5X Overview
A NAND gate is a fundamental digital logic primitive that performs the logical NAND (NOT-AND) operation on its two inputs. The output is logic LOW only when both inputs are HIGH; otherwise, the output is logic HIGH. As a member of the logic gate family, NAND gates sit inside the Boolean logic hierarchy (AND/OR/NOT/NAND/NOR/XOR), and the NAND gate is functionally complete, meaning any other Boolean function can be implemented using only NAND gates. Within an integrated circuit's hierarchy, the NC7S00 belongs to the logic ICs category, specifically the sub-category of gates and inverters, which feed into larger functions such as flip-flops, arithmetic logic units, and microcontrollers.
Key features of the NC7S00M5X include ultra-low quiescent current (ICC < 1 µA at VCC = 5.5 V), high noise immunity thanks to three internal gain stages between input and output, balanced output drive, and ESD protection diodes on all inputs/outputs referenced to the VCC and GND rails. The SOT-23-5 footprint makes it suitable for space-constrained designs such as hand-held, battery-powered, and portable consumer electronics.
Architecturally, the NC7S00 uses an advanced silicon-gate CMOS process that combines low static power consumption with high switching speed. The output stage is balanced, capable of sourcing and sinking comparable currents, which improves AC performance in symmetrical loads and prevents ground-bounce issues in dense multi-gate boards. Inputs tolerate voltages up to VCC plus 0.5 V without damage.
Typical applications include handheld and portable electronics, general-purpose logic level translation and interface buffering, signal conditioning in sensor front-ends, low-power standby controllers, mobile phones, PDAs, and industrial control logic where minimal board area is critical. Designers often use the NC7S00M5X as a building block for oscillator circuits, reset sequencers, and conditional-enable logic.
When designing with this device, observe proper high-frequency PCB practices: place a 0.1 µF decoupling capacitor within 2 mm of the VCC pin, and route input traces away from the output to avoid feedback-induced oscillations. The input ESD network makes the pin robust to handling, but layout cleanliness still determines overall system noise immunity.

Typical Applications
NC7S00M5X is suitable for 6 applications: Handheld Portable Electronics, General Logic Level Translation and Interface Buffering, Signal Conditioning in Sensor Front-Ends, Low-Power Standby and Reset Sequencing, Mobile Phone and PDA Peripherals, IoT and Smart-Home Sensor Nodes.
Handheld Portable Electronics
The NC7S00M5X is well matched to handheld portable electronics because its sub-1 µA quiescent current at 5.5 V minimizes battery drain during standby, while the 5-pin SOT-23-5 footprint saves board space in size-constrained wearables and PDAs. Operating from 2.0 V to 6.0 V, it interfaces directly with 3.3 V MCUs and 5 V peripheral chips without level shifters. Designers typically place the part near a GPIO to perform conditional inversion, oscillator feedback, or wake-event gating. The CMOS-balanced output drive (±mA-class sourcing and sinking) supports clean edges even at the high-impedance state transitions common in low-duty-cycle portable wake loops.
Recommended
General Logic Level Translation and Interface Buffering
The NC7S00M5X serves as a compact logic buffer between mismatched-voltage domains, particularly 3.3 V MCUs driving 5 V peripherals or 1.8 V sensors driving 3.3 V logic. Because the inputs are tolerant up to VCC + 0.5 V when powered at lower VCC, the part can be safely fed from a higher-voltage rail while producing a lower-voltage output, implementing a single-bit unidirectional level translator. The 2.0 V to 6.0 V supply range covers the most common logic levels in mixed-signal designs, and the 3-stage internal gain assures high noise immunity even in electrically noisy industrial environments.
Recommended
Signal Conditioning in Sensor Front-Ends
In sensor front-ends the NC7S00M5X is used to combine sensor flags, debounce mechanical switch inputs, or build an alarm window detector. Its high noise immunity from the 3-stage internal gain helps reject transient noise on long sensor cables, and the balanced CMOS output drives both the analog-front-end enable line and a digital interrupt pin without skew. Operating temperature of -40 °C to +85 °C supports industrial sensor deployments. Designers should still add an RC debounce network or a Schmitt-triggered variant (NC7ST00M5X) for very noisy mechanical inputs where bounce exceeds a few milliseconds.
Recommended
Low-Power Standby and Reset Sequencing
The NC7S00M5X is widely used in standby controllers, reset-sequencer blocks, and power-gating logic. Its sub-1 µA quiescent current lets it remain always-on in battery-backed systems without measurably draining reserve capacity. A common configuration ties two inputs together to create a single-input inverter, or cascades two NC7S00 gates to build a set-reset latch. Because the device is rated 2.0 V to 6.0 V, the same part can be used in 3.3 V RTC domains and 5 V main-rail domains without separate BOM entries.
Recommended
Mobile Phone and PDA Peripherals
Mobile phone and PDA subsystems often need a tiny NAND gate to combine charger-detect, USB-ID, and headset-sense flags. The NC7S00M5X's 5-pin SOT-23-5 footprint occupies less than 9 mm² of board area including its keep-out, ideal for sub-50 mm² peripheral modules. The CMOS-balanced output source/sink current cleanly drives an interrupt pin or a power-mux control FET. ESD protection diodes on all I/O pins (referenced to VCC and GND) safeguard the gate against the IEC 61000-4-2 air-discharge events common in handheld-handling scenarios, though an external TVS is still recommended for USB-charging pins.
Recommended
IoT and Smart-Home Sensor Nodes
IoT and smart-home sensor nodes use the NC7S00M5X to combine interrupt flags from multiple low-power sensors (PIR, door, temperature) before waking the host MCU. The sub-1 µA quiescent current preserves battery life across multi-year deployments, and the wide 2.0-6.0 V supply range supports both 3.3 V coin-cell designs and 5 V USB-powered hubs. The part's CMOS-balanced output drive cleanly toggles a 1 MHz GPIO interrupt without bounce, and its small footprint allows integration into coin-cell-sized sensor puck designs. For battery nodes in extreme temperature, verify the -40 °C to +85 °C operating range covers the deployment environment.

Key Differentiators
- Tiny single-gate SOT-23-5 footprint vs 14-pin quad-gate packages (vs 74HC00 (SOIC-14))
- Schmitt-trigger option in same footprint (vs NC7S00M5X (standard))
- Cross-brand dual-sourcing with pin-compatible footprint (vs SN74LVC1G00DBVR (Texas Instruments))
Design Notes
Place a 0.1 µF X7R ceramic decoupling capacitor within 2 mm of the VCC pin (pin 5) of the SOT-23-5 package. Estimated: typical high-speed CMOS gate switching transients draw 10-20 mA peaks for <5 ns; the decoupling cap supplies this without disturbing the upstream rail. Keep the GND via array immediately adjacent to pin 2 to minimize return-path inductance for high-speed edges.
Route input traces (pins 1, 3) away from the output trace (pin 4) to avoid capacitive feedback that can cause double-pulsing or oscillation. Estimated: SOT-23-5 pin-to-pin capacitance is ~1-2 pF; at 50 MHz this is sufficient coupling to disturb clean edges if traces run parallel for more than ~5 mm. Maintain at least 0.5 mm separation between output trace and either input trace.
Do not apply inputs (pins 1, 3) higher than VCC + 0.5 V when VCC is powered; the ESD diode will forward-conduct and inject current into the supply rail, potentially disturbing other parts. For level-shifting use cases, power the NC7S00M5X at the higher of the two logic voltages and feed the lower-voltage rail into the inputs - the CMOS input thresholds scale with VCC. Also avoid leaving inputs floating; an undriven CMOS input can drift into the linear region and cause supply-current oscillation.
