Product details
Overview
MC74ACT11D from onsemi is a triple 3-input AND gate logic IC with TTL-compatible inputs, designed for high-speed digital signal routing in industrial control and embedded interface circuits. It operates at 4.5–5.5 V, delivers ±24 mA output drive, exhibits 9.5 ns max propagation delay (5 V, CL = 50 pF), and uses SOIC-14 (Case 751A) packaging.
For engineers reviewing the MC74ACT11D datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin mapping, confirmed AC/DC electrical specs, real-world use context, and two technically documented alternative parts for logic-level compatibility assessment.
Technical Context
The MC74ACT11D implements three independent 3-input AND gates in a single monolithic CMOS device. Its TTL-compatible inputs accept standard 0.8 V/2.0 V logic thresholds, enabling direct interfacing with legacy 74LS and microcontroller GPIOs without level-shifting.
It features rail-to-rail output swing (VOH ≥ 4.4 V, VOL ≤ 0.44 V at 5.5 V, IOL/IOH = ±24 mA), low input capacitance (4.5 pF), and guaranteed operation across −40°C to +85°C ambient temperature - making it suitable for noise-immune combinatorial logic in mixed-signal systems.
Key Specifications

Pinout & Package
MC74ACT11D is housed in a 14-lead SOIC package (Case 751A), 8.55–8.75 mm × 3.80–4.00 mm body size, 1.35–1.75 mm height, with gull-wing leads and Pb-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 13 | Input A1, B1, C1 | First AND gate inputs - all three must be HIGH for Y1 output assertion |
| 3 | Output Y1 | Active-HIGH output of Gate 1 - drives downstream logic or loads up to 24 mA |
| 4, 5, 12 | Input A2, B2, C2 | Second AND gate inputs - independent of Gate 1; no internal coupling |
| 6 | Output Y2 | Active-HIGH output of Gate 2 - electrically isolated, same drive strength as Y1 |
| 8 | GND | Ground reference for all inputs, outputs, and internal circuitry - mandatory 0 V return path |
| 14 | VCC | Positive supply terminal - must be decoupled locally (e.g., 0.1 µF ceramic) near pin 14 |
| 9, 10, 11 | Input A3, B3, C3 | Third AND gate inputs - fully identical timing and threshold behavior to Gates 1 and 2 |
| 13 | Output Y3 | Active-HIGH output of Gate 3 - shares same SOIC thermal and electrical characteristics as Y1/Y2 |

Applications
| Industrial PLC Input Conditioning | Microcontroller Peripheral Enable Logic |
|---|---|
Use Scenario: Filtering and validating multiple sensor status signals before feeding to a PLC CPU module. IC Role / Device Role / Timing Role: Combinatorial enable gate - only asserts output when all three safety interlock sensors are active.

| Legacy System Bus Decoding | Test Equipment Signal Gating |
Use Scenario: Decoding address and control lines in retro-computing or instrumentation backplanes using 5 V TTL signaling. IC Role / Device Role / Timing Role: Address decoder element - combines A15, A14, and /CS to select a specific I/O peripheral region. Use Value: Maintains signal integrity across long traces due to low input capacitance (4.5 pF) and rail-to-rail output swing. |
Use Scenario: Gating test pulses in automated test equipment where precise timing and load drive are required. IC Role / Device Role / Timing Role: Pulse synchronizer - ANDs trigger, enable, and calibration signals to generate a clean, jitter-free output pulse. Use Value: Delivers consistent 10.5 ns propagation with minimal skew between channels, critical for sub-100 ns timing windows. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT11DR | Identical logic function, pinout, and DC/AC specs; TI-manufactured, same SOIC-14 package | No functional deviation - validated drop-in replacement per TI SN74ACT11 datasheet Rev. D (2021) | Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation |
| 74VHC11M | Higher VCC range (2–5.5 V); lower drive (±8 mA); faster typical delay (5.5 ns @ 5 V) but narrower noise margin (VIH = 3.5 V min) | Not TTL-compatible - requires level translation if interfacing with 74LS or legacy 5 V logic | Prefer for 3.3 V–5 V mixed-supply systems where power efficiency outweighs drive strength and TTL interoperability |
Compared with SN74ACT11DR, MC74ACT11D offers identical performance and fit but differs in manufacturer qualification and traceability; compared with 74VHC11M, MC74ACT11D provides superior noise immunity and load drive at the cost of narrower supply voltage flexibility.

FAQ
What logic family does the MC74ACT11D belong to, and how does it differ from standard 74AC devices?
The MC74ACT11D belongs to the 74ACT (Advanced CMOS TTL-compatible) family. Unlike 74AC devices, which have CMOS input thresholds (VIH ≈ 3.15 V at 5 V), the MC74ACT11D features TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max), allowing direct connection to 74LS, microcontrollers, and other legacy 5 V logic without level shifting. This distinction is explicitly defined in the "RECOMMENDED OPERATING CONDITIONS" and "DC CHARACTERISTICS" tables of the MC74AC11/MC74ACT11 datasheet Rev. 7.
Is the MC74ACT11D rated for 3.3 V operation?
No, the MC74ACT11D is not rated for 3.3 V operation. Its recommended VCC range is strictly 4.5 V to 5.5 V, as specified in the "RECOMMENDED OPERATING CONDITIONS" table. At 3.3 V, input thresholds (VIH/VIL) and output drive (VOH/VOL) are not guaranteed, and AC performance (e.g., propagation delay) is undefined. For 3.3 V systems, consider 74LVC11 or 74AHC11 instead.
Does the MC74ACT11D support mixed-voltage interfacing, such as connecting to 3.3 V microcontrollers?
The MC74ACT11D can accept 3.3 V logic HIGH inputs safely - its VIH is specified at 2.0 V min (at VCC = 4.5–5.5 V), well below 3.3 V. However, its outputs swing rail-to-rail (≈4.4–5.4 V HIGH), so direct connection to 3.3 V-only inputs requires a level-shifter or series resistor + clamping diode. The datasheet confirms input voltage limits extend to VCC +0.5 V, protecting against overvoltage from 3.3 V drivers.
What is the maximum capacitive load the MC74ACT11D can drive while maintaining specified propagation delay?
The MC74ACT11D's AC specifications (propagation delay tPLH/tPHL) are characterized at CL = 50 pF, as stated in the "AC CHARACTERISTICS" table. Driving loads significantly above 50 pF increases delay nonlinearly and may cause waveform degradation. For reliable timing at full spec, keep total load (including trace capacitance and input capacitance of downstream devices) ≤50 pF. The device's 24 mA drive strength supports heavier loads but with degraded speed and potential ringing.
Is the MC74ACT11D pin-compatible with the MC74AC11D?
Yes, the MC74ACT11D and MC74AC11D share identical pinouts, package (SOIC-14), and logic function (triple 3-input AND). However, they differ electrically: MC74AC11D has CMOS input thresholds (VIH = 3.15 V min at 5 V) and operates down to 2.0 V VCC, while MC74ACT11D requires 4.5–5.5 V and accepts TTL-level inputs. Substitution is mechanically possible but functionally valid only if input voltage levels and supply constraints align.
