Product details
Overview
NC7ST04P5X from ON Semiconductor is a single high-performance CMOS inverter with TTL-compatible inputs, designed for level-shifting and signal inversion in low-voltage digital logic interfaces. It operates from 4.5 V to 5.5 V, delivers ±2 mA output drive, achieves <7 ns typical propagation delay at 5 V/15 pF, and consumes <1 µA quiescent current - enabling use in battery-powered portable instrumentation and industrial control I/O buffers.
For engineers reviewing the NC7ST04P5X datasheet, pinout, applications, or equivalent options, key selection criteria include its SC70-5 package footprint, balanced ±2 mA drive strength, TTL-compatible input threshold (VIH = 2.0 V min), and guaranteed operation across −40°C to +85°C ambient.
Technical Context
The NC7ST04P5X implements a single-stage CMOS inverter topology with advanced silicon gate fabrication, delivering high noise immunity via high-gain circuitry and reduced sensitivity to input edge rate. Its TTL-compatible inputs accept standard 5 V logic thresholds while operating from a 4.5–5.5 V supply, enabling seamless interfacing between legacy TTL and modern CMOS systems.
ESD protection diodes are integrated on both input and output terminals relative to VCC and GND rails, and the device meets absolute maximum ratings including ±20 mA DC input/output diode current and 150°C junction temperature - supporting robust operation in noisy industrial environments without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard 5 V logic rails and tolerant of ±5% regulation variation |
| Propagation Delay | <7 ns typ @ 5 V, 15 pF - supports >100 MHz toggle rates in short trace applications |
| Output Drive | ±2 mA - sufficient to drive multiple 74HC inputs or small capacitive loads without buffering |
| Quiescent Current | <1 µA typ @ 5.5 V - enables ultra-low static power in always-on monitoring circuits |
| Input Threshold | VIH = 2.0 V min, VIL = 0.8 V max - ensures reliable recognition of TTL-level signals at 5 V supply |
| Operating Temp | −40°C to +85°C - qualified for industrial-grade embedded control and sensor interface modules |
| ESD Rating | Integrated diode protection to ±20 mA - eliminates need for external TVS on I/O lines in moderate-noise environments |
Pinout & Package
NC7ST04P5X is housed in a 5-lead SC70 package (EIAJ SC-88a, 1.25 mm wide), optimized for space-constrained PCB layouts and reflow-compatible assembly. The package has exposed pad-free construction and JEDEC-compliant thermal resistance (θJA = 425°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (A) | Digital signal entry point; TTL-compatible threshold allows direct connection to 74LS/74F outputs |
| 2 | GND | Ground reference for logic levels and internal ESD protection paths |
| 3 | Output (Y) | Inverted logic output; capable of sourcing/sinking ±2 mA into capacitive or resistive loads |
| 4 | NC | No-connect terminal; must remain unconnected per datasheet - not internally tied or usable |
| 5 | VCC | Positive supply rail; decoupling capacitor (0.1 µF) recommended within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input | Accepts standard 5 V TTL logic thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) while powered from 4.5–5.5 V supply |
| Balanced output drive | Delivers symmetrical ±2 mA sink/source capability - avoids duty cycle distortion in clock inversion |
| Ultra-low ICC | Quiescent current <1 µA at 5.5 V enables use in wake-on-event sensor nodes with multi-year battery life |
| High-speed tPD | Typical 3.5–4.5 ns propagation delay at 5 V/15 pF supports clean signal inversion up to ~140 MHz |
| Integrated ESD protection | On-chip diodes guard A and Y pins against ±20 mA transient currents - reduces BOM count in non-military designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Wider VCC range (1.65–5.5 V); lower VIH (0.7×VCC); higher speed (tPD ≈ 3.5 ns typ) | Supports mixed-voltage systems (1.8 V/3.3 V/5 V); less suitable for pure 5 V TTL interface due to input threshold dependency | Select when operating below 4.5 V or requiring voltage-level flexibility; verify VIH/VIL compatibility with source logic family |
| 74AUP1G04GW,125 | Lower ICC (<0.9 µA typ); wider temp range (−40°C to +125°C); smaller XSON-6 package | Better suited for automotive under-hood modules; lacks TTL-compatible input - requires 3.3 V logic sources | Choose for extended temperature or ultra-low-power automotive applications; not drop-in for TTL-driven systems |
Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the NC7ST04P5X uniquely guarantees TTL-compatible input thresholds at 5 V while maintaining SC70-5 footprint and <1 µA ICC - making it optimal for legacy 5 V industrial control upgrades where input signal origin is fixed TTL.

FAQ
What is the maximum operating frequency supported by the NC7ST04P5X?
The NC7ST04P5X does not specify a maximum clock frequency in its datasheet, but its typical propagation delay of <7 ns at 5 V/15 pF implies reliable operation up to approximately 100 MHz in well-terminated, low-capacitance traces. Actual toggle rate depends on load capacitance and PCB layout; for 50 pF loads, tPHL/tPLH increases to ~16–17 ns, limiting practical use to ~30 MHz. Always validate timing margins in the final NC7ST04P5X application.
Can the NC7ST04P5X be used with a 3.3 V supply?
No - the NC7ST04P5X is specified only for 4.5 V to 5.5 V operation per its Recommended Operating Conditions. At 3.3 V, input thresholds (VIH = 2.0 V min) become incompatible with standard 3.3 V logic families, and output drive degrades significantly. For 3.3 V systems, consider SN74LVC1G04DBVR instead. The NC7ST04P5X must be operated within its rated 4.5–5.5 V window to guarantee correct functionality.
Is Pin 4 (NC) on the NC7ST04P5X safe to connect to ground or leave floating?
Pin 4 is explicitly designated "No Connect" in the NC7ST04P5X datasheet and must remain unconnected - neither grounded nor tied to any voltage. It is not internally bonded and has no electrical function. Connecting it may cause unpredictable behavior or damage due to internal routing. Always follow the NC7ST04P5X pinout diagram and leave Pin 4 floating and unpopulated on the PCB.
Does the NC7ST04P5X require external pull-up or pull-down resistors on its input?
No - the NC7ST04P5X input is actively driven and does not require external biasing. However, unused inputs must never float: if an NC7ST04P5X is used in a design where the input signal may be disconnected, tie the A pin to VCC or GND via a resistor (e.g., 10 kΩ) to prevent metastability. This requirement applies to all NC7ST04P5X units in the system, regardless of signal activity.
How does the NC7ST04P5X compare to the NC7ST04M5X in terms of thermal performance?
The NC7ST04P5X uses an SC70-5 package with θJA = 425°C/W, while the NC7ST04M5X (SOT23-5) has θJA = 300°C/W. Under identical 5 V/2 mA load conditions, the NC7ST04P5X will run ~40°C hotter at the die junction. For thermally constrained applications drawing sustained output current, the NC7ST04M5X offers superior heat dissipation. Both share identical electrical specs - the choice depends on board space and thermal budget, not logic behavior. The NC7ST04P5X remains valid for low-duty-cycle or intermittent use.
