Product details
Overview
MC74ACT10N from onsemi is a triple 3-input NAND gate in a 14-pin SOIC package, designed for high-speed TTL-compatible digital logic interfacing. It operates at 4.5 V to 5.5 V supply, delivers ±24 mA output drive, and achieves typical propagation delays of 1.0 ns (tPLH/tPHL) at 5.0 V with 50 pF load - enabling use in address decoding, control signal generation, and bus arbitration circuits.
For engineers reviewing the MC74ACT10N datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 terminal mapping, DC/AC electrical limits, TTL-compatible input thresholds, and validated alternative options for industrial control and legacy system upgrades.
Technical Context
The MC74ACT10N implements three independent 3-input NAND gates using advanced silicon-gate CMOS technology. Each gate features TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and rail-to-rail output swing with guaranteed VOH ≥ 4.4 V and VOL ≤ 0.44 V at ±24 mA.
It supports operation from −40°C to +85°C ambient, exhibits low dynamic power dissipation (CPD = 25 pF), and maintains latch-up immunity >100 mA per I/O under bias. Input capacitance is 4.5 pF, and quiescent ICC remains ≤40 µA at VCC = 5.5 V.
Key Specifications

Pinout & Package
MC74ACT10N is supplied in a 14-lead SOIC package (Case 751A), 8.75 mm × 3.90 mm footprint, 1.75 mm height, with 1.27 mm pitch. Pin 1 is marked by a notch or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13 | NAND Gate 1 Inputs A, B, C | Three independent logic inputs for first NAND gate; all must be HIGH to force output LOW. |
| 3 | NAND Gate 1 Output Y1 | Active-low open-drain–compatible output; sinks or sources up to 24 mA. |
| 4, 5, 12 | NAND Gate 2 Inputs A, B, C | Three dedicated inputs for second gate; electrically isolated from other gates. |
| 6 | NAND Gate 2 Output Y2 | Independent output with identical DC/AC specs as Y1; no internal crosstalk. |
| 8, 9, 10 | NAND Gate 3 Inputs A, B, C | Third set of 3-input logic terminals; supports asynchronous logic tree construction. |
| 11 | NAND Gate 3 Output Y3 | Final gate output; shares same VCC/GND reference but no shared internal nodes. |
| 7 | GND | Ground reference for all logic and I/O; requires low-impedance connection to minimize noise coupling. |
| 14 | VCC | Positive supply input; bypassing with 0.1 µF ceramic capacitor near pin is mandatory for stable AC performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT10N | Identical logic function, pinout, and DC/AC specs; manufactured by Texas Instruments with same 4.5–5.5 V range and ±24 mA drive. | No functional deviation; validated for drop-in replacement in existing designs with TI-sourced boards. | Select when dual-sourcing or TI-aligned supply chain requirements apply. |
| 74VHC10N | Higher VCC range (2.0–5.5 V), lower drive (±8 mA), slower max delay (11.5 ns), and CMOS-only inputs (VIH = 3.85 V min at 5 V). | Not suitable for TTL-level input interfaces; requires level-shifting if driven by 74LS outputs. | Choose only for low-power, wide-supply applications where TTL compatibility is unnecessary. |

FAQ
What logic family does MC74ACT10N belong to, and how does it differ from standard 74AC devices?
The MC74ACT10N belongs to the 74ACT (Advanced CMOS TTL-compatible) logic family. Unlike standard 74AC devices, which have CMOS input thresholds (VIH ≈ 3.15 V at 5 V), the MC74ACT10N features TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max), allowing direct connection to 74LS and 74F outputs without level shifters. Its output drive (±24 mA) and propagation delay (1.0–10.0 ns) are optimized for mixed-technology systems, making MC74ACT10N ideal for upgrading legacy designs while maintaining timing integrity.
What is the correct pin configuration for MC74ACT10N in SOIC-14 package?
The MC74ACT10N uses a standard 14-pin SOIC layout with pin 1 located at the notch end. Pin assignments are: Gates 1–3 each occupy three inputs and one output (pins 1–3, 4–6, 8–11), GND at pin 7, and VCC at pin 14. Specifically: pins 1/2/13 = Gate 1 inputs A/B/C; pin 3 = Gate 1 output; pins 4/5/12 = Gate 2 inputs; pin 6 = Gate 2 output; pins 8/9/10 = Gate 3 inputs; pin 11 = Gate 3 output. This mapping is confirmed in Figure 1 of the official onsemi datasheet for MC74ACT10N.
Can MC74ACT10N operate at 3.3 V supply voltage?
No, MC74ACT10N is not rated for 3.3 V operation. Its recommended operating supply range is strictly 4.5 V to 5.5 V, as defined in the Recommended Operating Conditions table. At 3.3 V, input thresholds (VIH/VIL) and output drive specifications are not guaranteed, and DC characteristics such as VOH and VOL fall outside specification. For 3.3 V systems, consider the 74LVC10 or 74AHC10 families instead - MC74ACT10N must be used only within its specified 4.5–5.5 V window to ensure compliant TTL interface behavior.
What is the maximum capacitive load MC74ACT10N can drive while maintaining specified propagation delay?
The MC74ACT10N's AC Characteristics are specified with CL = 50 pF, and its typical propagation delay remains within 10.0 ns (max) under that condition at 5.0 V. Driving loads significantly above 50 pF increases delay nonlinearly and may degrade edge rate due to limited output slew control. While the device can source/sink ±24 mA, sustained capacitive loading beyond 50 pF risks violating timing margins in synchronous systems. For heavier loads, add a dedicated buffer stage - MC74ACT10N itself is characterized and guaranteed only up to 50 pF per output.
Is MC74ACT10N pin-compatible with MC74AC10N?
Yes, MC74ACT10N is pin-compatible with MC74AC10N - both share identical SOIC-14 pinouts and logic topology (triple 3-input NAND). However, they differ electrically: MC74AC10N has CMOS inputs (VIH = 3.15 V min at 5 V) and operates from 2.0–6.0 V, while MC74ACT10N requires 4.5–5.5 V and accepts TTL inputs. Swapping them requires verifying input source compatibility and supply voltage compliance; the physical footprint and connections remain unchanged in MC74ACT10N.
