Product details
Overview
MC74ACT11ML1 from onsemi is a triple 3-input AND gate IC with TTL-compatible inputs, operating at 4.5 V to 5.5 V supply, delivering ±24 mA output drive, and supporting propagation delays as low as 1.5 ns (typ) at 5 V - used in high-speed digital logic interfacing and bus control circuits.
For engineers reviewing the MC74ACT11ML1 datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V operation, TTL input compatibility, 24 mA drive strength, AC/ACT family timing behavior, and EIAJ-14 (CASE 965) surface-mount package.
Technical Context
The MC74ACT11ML1 implements three independent 3-input AND gates in a single monolithic CMOS structure, designed for 5 V systems with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max). It uses advanced silicon-gate technology to achieve AC-compatible speed while maintaining ACT-series noise immunity and drive capability.
Its logic function conforms strictly to Boolean Y = A • B • C per gate, with guaranteed rail-to-rail output swing (VOH ≥ 4.4 V, VOL ≤ 0.44 V at IOL = 24 mA), and operates across –40°C to +85°C ambient temperature with quiescent ICC ≤ 40 µA.

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 | SOIC-14 package (CASE 751A); identical AC/ACT electrical specs and pinout | Requires PCB layout change due to different footprint and lead form (gull-wing vs. gull-wing SOIC) | Select when SOIC assembly infrastructure is preferred and thermal/mechanical constraints permit larger body size |
| 74VHC11M | Higher VCC range (2–5.5 V); lower drive (±8 mA); slower max delay (14 ns); CMOS-only inputs | Not TTL-compatible; unsuitable for direct interface with 74LS outputs without pull-up or level shift | Choose only for mixed-voltage designs needing 3.3 V operation or ultra-low static power (<2 µA), not for 5 V TTL interoperability |
Compared with SN74ACT11DR and 74VHC11M, the MC74ACT11ML1 uniquely combines EIAJ-14 mechanical compatibility, full TTL input recognition, and 24 mA drive in a compact PLCC outline - making it optimal for space-constrained industrial modules requiring legacy signal interoperability.

FAQ
What logic function does the MC74ACT11ML1 implement?
The MC74ACT11ML1 implements three independent 3-input AND gates (Y = A • B • C per gate), each with TTL-compatible inputs and rail-to-rail CMOS outputs. Its truth table and timing behavior are fully specified in the onsemi datasheet for the 74ACT series, and all three gates operate simultaneously with no internal interdependence. The MC74ACT11ML1 is not a programmable or configurable device - its logic function is fixed and deterministic.
Is the MC74ACT11ML1 pin-compatible with the MC74AC11ML1?
No, the MC74ACT11ML1 is not pin-compatible with the MC74AC11ML1 despite identical pin numbering and package outline. Their input threshold specifications differ significantly: MC74ACT11ML1 requires VIH ≥ 2.0 V (TTL-compatible), while MC74AC11ML1 requires VIH ≥ 3.15 V at 4.5 V (CMOS-compatible). Interchanging them may cause logic misreads in systems driven by TTL-level sources. Always verify input voltage compatibility before substitution.
What is the maximum capacitive load the MC74ACT11ML1 can drive reliably?
The MC74ACT11ML1 is characterized for CL = 50 pF in AC testing, with propagation delays specified up to that load. At 24 mA output current and 5 V supply, it can reliably drive ≥200 pF total load (including trace and input capacitance) while staying within its 10.5 ns max tPLH/tPHL spec - confirmed by onsemi's dynamic output current ratings (IOHD = –75 mA, IOLD = 75 mA) and measured waveform fidelity in application notes. Exceeding 300 pF may degrade timing margins.
Does the MC74ACT11ML1 support operation at 3.3 V supply?
No, the MC74ACT11ML1 is not rated for 3.3 V operation. Its recommended VCC range is strictly 4.5 V to 5.5 V, and its TTL-compatible input thresholds (VIH = 2.0 V min) are defined only within that range. Operation below 4.5 V risks undefined logic states, increased propagation delay, and potential failure to recognize TTL-high inputs. For 3.3 V systems, consider the 74LVC11 or 74AUP1G11 families instead of the MC74ACT11ML1.
What package type is used for the MC74ACT11ML1 suffix "L1"?
Per onsemi's ordering information and marking diagrams, the "L1" suffix in MC74ACT11ML1 denotes the EIAJ-14 package (CASE 965), a 14-pin plastic leaded chip carrier (PLCC) with gull-wing leads and 0.65 mm pitch. This is distinct from "D" (SOIC-14), "N" (PDIP-14), and "DT" (TSSOP-14) variants. The MC74ACT11ML1 uses this specific outline for improved thermal dissipation and board-level reliability in industrial mounting.
