Product details

Overview

74F10SC 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 digital control, address decoding, and bus arbitration circuits.

For engineers reviewing the 74F10SC 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), junction temperature range (–55°C to +150°C), and JEDEC MS-012 SOIC packaging compatibility.

Technical Context

The 74F10SC implements three independent NAND gates using Fairchild's FAST (Fairchild Advanced Schottky TTL) process, optimized for high-speed digital logic with balanced tPLH/tPHL asymmetry and controlled output transition times. It supports standard TTL-level interfacing with VIH/VIL defined at 2.0 V/0.8 V and operates across industrial ambient temperatures (0°C to +70°C).

DC characteristics include IIL = –0.6 mA (max), IOH = –1 mA (min), IOL = 20 mA (max), and power supply currents ICCH = 2.1 mA (max) and ICCL = 7.7 mA (max), enabling robust noise margin and load-driving capability in multi-gate logic networks.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	+4.5 V to +5.5 V - ensures compatibility with standard 5 V TTL systems and tolerance against rail droop.
Propagation Delay	tPHL = 1.5–5.3 ns, tPLH = 2.4–6.0 ns - enables sub-5 ns gate-to-gate timing in synchronous logic paths.
Output Drive	IOH = –1 mA, IOL = 20 mA - supports direct driving of multiple TTL inputs or small capacitive loads without buffering.
Input Thresholds	VIH = 2.0 V (min), VIL = 0.8 V (max) - provides ≥0.4 V DC noise margin under worst-case conditions.
Fan-Out	HIGH: 50, LOW: 33.3 - allows cascading into up to 50 standard TTL inputs without signal degradation.
Operating Temperature	TA = 0°C to +70°C - certified for commercial-grade digital system environments.

Pinout & Package

74F10SC is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body, with 1.27 mm pitch and gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 13	Gate 1 Inputs (A1, B1, C1)	Three independent logic inputs for first NAND gate; TTL-compatible voltage thresholds apply.
3	Gate 1 Output (O1)	Active-low open-collector-equivalent output capable of sinking 20 mA.
4, 5, 12	Gate 2 Inputs (A2, B2, C2)	Inputs for second independent 3-input NAND function; electrically isolated from other gates.
6	Gate 2 Output (O2)	Dedicated output with same DC/AC specs as O1; no internal sharing or contention.
8, 9, 11	Gate 3 Inputs (A3, B3, C3)	Third set of inputs; pin 11 is C3 - layout follows standard 74-series SOIC numbering convention.
10	Gate 3 Output (O3)	Final gate output; all outputs are buffered, non-inverting relative to NAND logic function.
7	GND	Ground reference for all internal circuitry and I/O; must be low-impedance connection.
14	VCC	+5 V supply pin; decoupling capacitor (0.1 µF) recommended adjacent to pin.

Key Features

Feature	Design Value

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), identical AC/DC specs and pinout; slightly higher thermal resistance (θJA = 70°C/W vs. 100°C/W).	Preferred for through-hole prototyping or legacy board rework where SOIC footprint unavailable.	Select SN74F10N when manual soldering or socket-based testing is required; same logic behavior and timing.
74ACT10SC	Advanced CMOS (ACT) family: lower ICC (1 µA typ), wider VCC range (4.5–5.5 V), but reduced IOL (24 mA vs. 20 mA) and higher VIH (3.5 V min).	Suitable for mixed-voltage systems requiring 5 V tolerant inputs and lower static power, not TTL-level interoperability.	Choose 74ACT10SC only if system uses ACT-level signaling; not drop-in compatible due to VIH mismatch with legacy TTL.

Compared with SN74F10N and 74ACT10SC, the 74F10SC offers optimal balance of speed, TTL compatibility, and SOIC manufacturability - ideal for high-volume commercial logic boards where pinout, timing, and package form factor are fixed.

Manufacturer

Fairchild Semiconductor was a U.S.-based semiconductor company specializing in analog and logic ICs, acquired by ON Semiconductor in 2016; known for FAST, FACT, and TTL-compatible product families.

The 74F10SC belongs to Fairchild's FAST TTL logic series, designed for high-speed commercial digital systems where propagation delay, fan-out, and 5 V interoperability were critical design requirements.

FAQ

What logic family does the 74F10SC belong to?

The 74F10SC belongs to Fairchild's FAST (Fairchild Advanced Schottky TTL) logic family. It is a bipolar TTL device with Schottky-clamped transistors, delivering higher speed than standard 74LS while maintaining full TTL voltage and current compatibility. The 74F10SC exhibits typical propagation delays of 1.5–5.3 ns and supports standard TTL fan-out levels.

Is the 74F10SC pin-compatible with other 74F-series triple NAND packages?

Yes - the 74F10SC uses standard 14-pin SOIC pinout matching the industry-wide 74F10 footprint, including identical assignment of inputs (pins 1,2,13 for Gate 1; 4,5,12 for Gate 2; 8,9,11 for Gate 3) and outputs (pins 3,6,10). This enables direct substitution for any 74F10 variant in SOIC-14 (M14A) packaging, including 74F10SJ (SOP) in layout-adapted designs.

What is the maximum junction temperature rating for the 74F10SC?

The 74F10SC has a maximum junction temperature (TJ) rating of +150°C under bias, with storage temperature spanning –65°C to +150°C. Its SOIC package (M14A) exhibits a thermal resistance θJA of approximately 100°C/W under standard JEDEC test conditions, allowing safe operation in commercial ambient environments up to +70°C with appropriate PCB copper area.

Can the 74F10SC drive LED indicators directly?

No - the 74F10SC outputs are designed for logic-level interfacing, not direct LED drive. While its IOL rating is 20 mA, the VOL specification (0.5 V max at 20 mA) implies insufficient headroom for typical red/green LEDs (requiring ≥1.8 V forward voltage). Driving LEDs requires external current-limiting resistors and/or buffer transistors; the 74F10SC should be used for signal conditioning, not power switching.

Does the 74F10SC support mixed-voltage operation (e.g., 3.3 V inputs)?

No - the 74F10SC is strictly a 5 V TTL device. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and absolute maximum VIN (–0.5 V to +7.0 V) do not guarantee reliable recognition of 3.3 V logic HIGH signals. Applying 3.3 V inputs may result in marginal or undefined switching behavior; level-shifting circuitry is required for interfacing with 3.3 V systems. The 74F10SC must operate with VCC = +4.5 V to +5.5 V.
