Product details
Overview
MC74ACT10MELG from onsemi is a triple 3-input NAND gate in high-performance silicon-gate CMOS technology with TTL-compatible inputs, 24 mA output drive capability, propagation delay of 9.0 ns (max) at 5.0 V and 50 pF load, and operation across −40°C to +85°C ambient temperature - used in digital logic control, address decoding, and bus interface circuits.
For engineers reviewing the MC74ACT10MELG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, SOIC-14 package details, functional role in combinational logic systems, and validated alternative options for industrial and embedded designs.
Technical Context
The MC74ACT10MELG implements three independent 3-input NAND gates in a single monolithic CMOS die, each with buffered outputs and rail-to-rail voltage transfer characteristics. Its TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V at VCC = 4.5–5.5 V) enable direct interfacing with legacy 5 V TTL logic families without level-shifting.
It operates within a strict 4.5 V to 5.5 V supply range, supports dynamic output currents up to ±75 mA (pulse), and exhibits low input capacitance (4.5 pF) and power dissipation capacitance (25 pF), making it suitable for high-speed, low-noise digital signal routing in noise-sensitive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input NAND gate - provides three independent Boolean NOT-AND operations per device |
| Supply Voltage Range | 4.5 V to 5.5 V - requires tightly regulated 5 V rail; not compatible with 3.3 V or wide-range supplies |
| Propagation Delay | 9.0 ns max (tPLH/tPHL, VCC = 5.0 V, CL = 50 pF) - enables reliable operation in ≤100 MHz clock-domain edge sampling |
| Output Drive | ±24 mA DC - sufficient to directly drive multiple 74-series TTL inputs or small LED indicators without buffers |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max (VCC = 4.5–5.5 V) - ensures robust noise margin against TTL-level signals |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade deployment in non-automotive embedded systems |
| ESD Rating | HBM > 2000 V - meets basic handling requirements for manual assembly and board-level rework |

IC Role / Device Role / Timing Role: Priority encoder front-end implementing lockout logic with three enable inputs and one arbitration output. Use Value: Ensures glitch-free bus handoff via predictable NAND truth table behavior - no metastability risk. |
Use Scenario: Controlling startup sequence of auxiliary rails (e.g., analog bias, ADC reference) only after main 5 V rail stabilizes and two status flags are asserted. IC Role / Device Role / Timing Role: Power-good combiner that asserts "all-system-ready" signal when three upstream conditions converge. Use Value: Replaces RC-based timing networks with deterministic, temperature-stable logic - improves production yield and field reliability. |
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 |
|---|---|---|---|
| SN74ACT10DR | Identical logic function, same 4.5–5.5 V supply, 9 ns max delay, but TI-marked SOIC-14 with different thermal resistance (JA = 109°C/W vs. onsemi's 116°C/W) | Valid for drop-in replacement in existing PCB layouts; identical pinout and DC specs | Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation |
| 74VHC10M | Higher VCC range (2.0–5.5 V), lower drive (±8 mA), slower delay (11 ns max), and CMOS-only inputs (VIH = 3.85 V @ 5 V) | Not TTL-compatible; requires level translation if interfacing with legacy 74LS devices | Choose for mixed-voltage systems or ultra-low-power standby modes where 5 V-only operation is unnecessary |
Compared with SN74ACT10DR and 74VHC10M, the MC74ACT10MELG offers guaranteed TTL compatibility and superior output drive in a proven industrial SOIC package - making it optimal for legacy interface consolidation and noise-resilient control logic where input threshold matching is critical.

FAQ
What logic family does MC74ACT10MELG belong to, and how does it differ from standard 74AC devices?
The MC74ACT10MELG belongs to the 74ACT logic family, distinguished by TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V at 5 V) versus standard 74AC's CMOS thresholds (VIH = 3.15 V). This allows MC74ACT10MELG to interface directly with legacy 74LS and 74F logic without external pull-ups or level shifters - a key advantage in mixed-technology systems where MC74ACT10MELG replaces older bipolar logic while maintaining pinout and timing compatibility.
Is MC74ACT10MELG pin-compatible with other triple 3-input NAND packages like TSSOP-14?
No - MC74ACT10MELG uses the SOIC-14 package (Case 751A), whereas TSSOP-14 variants such as MC74ACT10DTR2G have different pad layouts, thermal profiles, and mechanical dimensions. While both share identical logic functionality and pin numbering, the SOIC-14 footprint of MC74ACT10MELG is not interchangeable with TSSOP-14 without PCB redesign. Always verify land pattern against onsemi's 751A-03 mechanical drawing before layout reuse.
What is the maximum capacitive load MC74ACT10MELG can drive while maintaining specified propagation delay?
The MC74ACT10MELG is characterized for CL = 50 pF in its AC specifications, with tPLH/tPHL guaranteed ≤9.0 ns at VCC = 5.0 V. Driving loads beyond 50 pF increases delay nonlinearly and may degrade noise margins; for >50 pF applications, buffer stages or lower-capacitance routing should be used. The MC74ACT10MELG's 25 pF power dissipation capacitance (CPD) confirms its optimization for moderate-speed, low-load digital interconnects - not high-fanout bus drivers.
Does MC74ACT10MELG support operation at 3.3 V supply voltage?
No - MC74ACT10MELG is specified only for 4.5 V to 5.5 V operation per its Recommended Operating Conditions table. At 3.3 V, input thresholds become undefined, output drive collapses below specification, and propagation delay exceeds guaranteed limits. For 3.3 V systems, consider 74LVC10 or 74AUP1G10 families instead. Using MC74ACT10MELG below 4.5 V risks functional failure and is outside its qualified operating envelope.
How is the "MELG" suffix decoded in MC74ACT10MELG, and what does it indicate about packaging and compliance?
The "MELG" suffix in MC74ACT10MELG identifies the specific ordering variant: "ME" denotes the SOIC-14 package with Pb-free finish, "L" indicates tape-and-reel packaging (2500 units per reel), and "G" certifies RoHS-compliant, lead-free construction per JEDEC J-STD-020. This matches onsemi's official ordering information where MC74ACT10DR2G uses the same suffix convention - confirming MC74ACT10MELG is a Pb-free, SOIC-14, tape-and-reel product intended for automated SMT assembly and industrial environmental compliance.
