Product details
Overview
74F10SCX from Fairchild Semiconductor is a triple 3-input NAND gate logic IC in 14-lead SOIC (M14A) package, operating at +4.5V to +5.5V supply, with propagation delays as low as 1.5 ns (tPHL) and 2.4 ns (tPLH), delivering TTL-compatible output drive (–1 mA / 20 mA), used in high-speed digital control and address decoding circuits.
For engineers reviewing the 74F10SCX datasheet, pinout, applications, or equivalent options, key selection considerations include guaranteed fan-out (50/33.3 HIGH/LOW), input voltage thresholds (VIH = 2.0 V, VIL = 0.8 V), output voltage specs (VOH ≥ 2.5 V at –1 mA, VOL ≤ 0.5 V at 20 mA), and industrial temperature range support (0°C to +70°C).
Technical Context
This device implements three independent 3-input NAND gates using Fairchild's FAST (Fairchild Advanced Schottky TTL) process, optimized for speed-power trade-off in medium-complexity combinational logic. Each gate accepts standard TTL-level inputs and drives TTL/CMOS loads with defined current sourcing/sinking capability.
It operates strictly within 5 V ±10% supply and requires no external biasing or pull-ups; all inputs feature clamp diodes (VCD = –1.2 V at –18 mA) and leakage-limited input currents (IIH ≤ 5.0 µA, IIL ≤ –0.6 mA), ensuring robust noise immunity in mixed-signal board environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +4.5 V to +5.5 V - ensures compatibility with standard 5 V TTL bus systems and stable operation across power rail tolerances. |
| Propagation Delay | tPHL = 1.5–5.3 ns, tPLH = 2.4–6.0 ns - enables reliable timing in sub-10 ns critical path designs at 70°C ambient. |
| Output Drive | IOH = –1 mA, IOL = 20 mA - supports direct interfacing to multiple TTL inputs (fan-out ≥ 50 HIGH, ≥ 33 LOW) without buffering. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees unambiguous logic level recognition across voltage and temperature variation. |
| Operating Temp | 0°C to +70°C - validated for commercial-grade embedded control, instrumentation, and industrial logic subsystems. |
| Power Dissipation | ICCL = 5.1–7.7 mA, ICCH = 1.4–2.1 mA - yields typical dynamic power < 35 mW per gate at 5 MHz toggle rate. |
Pinout & Package
74F10SCX is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body (Package Number M14A), with 1.27 mm lead pitch and surface-mount footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13 | Gate 1 Inputs (A1, B1, C1) | Three independent logic inputs for first NAND gate; each accepts standard TTL voltage levels and draws ≤5 µA HIGH current. |
| 3 | Gate 1 Output (O1) | Active-low open-collector–compatible output capable of sinking 20 mA or sourcing –1 mA under load. |
| 4, 5, 12 | Gate 2 Inputs (A2, B2, C2) | Inputs for second independent NAND gate; electrically identical to Gate 1 inputs with same VIH/VIL and loading. |
| 6 | Gate 2 Output (O2) | Second independent output with identical DC/AC specs to O1; enables parallel logic expansion without timing skew. |
| 8, 9, 10 | Gate 3 Inputs (A3, B3, C3) | Third set of 3-input logic terminals; fully isolated from other gates except shared VCC (pin 14) and GND (pin 7). |
| 11 | Gate 3 Output (O3) | Third output with matched propagation delay and drive strength; allows triple-gate logic functions in single-package footprint. |
| 7 | GND | Ground reference for all internal circuitry and I/O; must be low-impedance connection to minimize ground bounce. |
| 14 | VCC | +5 V supply pin; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent 3-input NAND gates | Enables compact implementation of multi-input logic functions (e.g., address enable, priority encoding) without inter-gate routing delay. |
| FAST TTL process technology | Delivers 2× speed improvement over standard 74LS series while maintaining pin compatibility and logic behavior. |
| Guaranteed fan-out of 50 (HIGH) / 33 (LOW) | Reduces need for buffer stages in dense logic arrays, lowering component count and board space in control-plane designs. |
| Input clamp diodes and controlled leakage | Provides ESD robustness (±2 kV HBM) and predictable interface behavior when driven by unterminated or mismatched sources. |
| Industrial-grade AC/DC electrical specs | Validated across full 0°C–70°C range with worst-case propagation delay and output voltage margins specified in datasheet tables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74F10N | Dual-in-line package (PDIP), same AC/DC specs, slightly higher tPLH/tPHL max at temperature extremes. | Preferred for through-hole prototyping or legacy board rework where SOIC footprint is unavailable. | Select SN74F10N only when manual soldering or socket-based testing is required; otherwise 74F10SCX offers superior thermal performance and density. |
| 74ACT11 | Advanced CMOS (ACT) family: 5 V tolerant, lower ICC (1 µA typ), but VIH/VIL thresholds differ (2.0 V/0.8 V same, but ACT has sharper transition). | Better for mixed-voltage systems with 3.3 V logic domains; not drop-in due to different input hysteresis and drive strength. | Choose 74ACT11 only when ultra-low static power or 3.3 V interface compatibility is mandatory; 74F10SCX remains optimal for pure 5 V TTL environments. |
Compared with SN74F10N and 74ACT11, the 74F10SCX delivers best-in-class propagation delay consistency across temperature, proven reliability in long-life industrial deployments, and SOIC packaging suited for automated SMT assembly-making it the preferred choice for new 5 V logic designs requiring speed and manufacturability.

FAQ
What is the maximum operating temperature range for the 74F10SCX?
The 74F10SCX is rated for commercial operation from 0°C to +70°C ambient temperature, as specified in the Recommended Operating Conditions table. It may survive storage up to +150°C (TSTG), but sustained operation outside the 0°C–70°C range is not guaranteed and may degrade timing margins or increase ICC.
Does the 74F10SCX support 3.3 V logic inputs?
No-the 74F10SCX is a 5 V TTL-family device with VIH = 2.0 V minimum and VIL = 0.8 V maximum; while 3.3 V logic HIGH may register correctly, marginal noise margins and undefined behavior below 2.0 V HIGH make it unsuitable for direct 3.3 V interface without level translation. The 74F10SCX requires a 5 V supply and TTL-compatible input sources.
How many independent logic gates are integrated in the 74F10SCX?
There are three independent 3-input NAND gates inside the 74F10SCX, each with dedicated inputs and outputs (pins 1/2/13→3, 4/5/12→6, 8/9/10→11). No internal sharing or coupling exists between gates beyond common VCC (pin 14) and GND (pin 7), enabling fully autonomous logic operations.
What is the recommended decoupling for the 74F10SCX?
A 0.1 µF ceramic capacitor placed as close as possible to pins 7 (GND) and 14 (VCC) is required for stable high-speed operation of the 74F10SCX. Additional bulk capacitance (e.g., 10 µF tantalum) may be added nearby for boards with multiple 74F10SCX devices or noisy power rails.
Is the 74F10SCX pin-compatible with the 74LS10?
Yes-the 74F10SCX shares identical pinout and logic function with the 74LS10, including input/output assignments and power/ground locations. However, the 74F10SCX offers faster propagation delays (≈2×), higher output drive, and improved noise immunity, making it a performance upgrade-not just a drop-in replacement-when board layout permits.
