Product details
Overview
MC74ACT08NG from onsemi is a quad 2-input AND gate in high-performance silicon-gate CMOS technology, featuring TTL-compatible inputs, 24 mA output drive capability, and operation across 4.5 V to 5.5 V supply range. It performs basic Boolean logic in digital control, address decoding, and enable gating functions within industrial and automotive systems.
For engineers reviewing the MC74ACT08NG datasheet, pinout, applications, or equivalent options, this device is selected for its robust noise immunity, fast propagation delay (≤10 ns at 5 V), AEC-Q100 qualification, Pb-free SOIC-14 packaging, and compatibility with legacy TTL logic levels.
Technical Context
The MC74ACT08NG implements four independent AND gates using advanced CMOS process technology optimized for speed-power trade-offs. Each gate accepts TTL-level inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and delivers rail-to-rail CMOS outputs with symmetrical ±24 mA drive strength.
It operates over −40°C to +85°C ambient temperature and supports stable logic interfacing in mixed-signal environments due to low input leakage (±1.0 µA max) and tight VOL/VOH specs (VOL ≤ 0.44 V at IOL = 24 mA; VOH ≥ 3.76 V at IOH = −24 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - enables parallel Boolean conjunction of four signal pairs |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and CMOS systems |
| Propagation Delay | ≤10.0 ns at VCC = 5.0 V, CL = 50 pF - supports >50 MHz toggle rates in combinatorial paths |
| Output Drive | ±24 mA - drives multiple LS-TTL loads or short PCB traces without buffering |
| Input Compatibility | TTL-compatible - interfaces directly with 74LS, 74F, and microcontroller GPIOs without level shifters |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive under-hood applications |

|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Input (A/B per gate) | Eight total inputs distributed across four AND gates (e.g., Pin 1 & 2 = Gate 1 inputs) |
| 3, 6, 10, 11 | Output (Y per gate) | Four independent AND outputs (e.g., Pin 3 = Gate 1 output) |
| 7 | GND | Ground reference for all logic and power domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT08DR | Same logic function, identical AC/DC specs, TI-branded SOIC-14 package | No AEC-Q100 qualification; rated only for commercial temperature range (0°C to 70°C) | Select when automotive qualification is unnecessary and TI supply chain preference applies |
| 74VHC08M | Higher VCC range (2 V–5.5 V); lower drive (±8 mA); no TTL input compatibility | Requires level-shifting for TTL sources; suited for low-power, wide-VCC battery-operated systems | Select when supply voltage flexibility and ultra-low ICC (<2 µA) outweigh drive and interface requirements |
Compared with SN74ACT08DR and 74VHC08M, the MC74ACT08NG uniquely combines AEC-Q100 qualification, full TTL input compatibility, and ±24 mA drive in a single SOIC-14 device - making it the preferred choice for automotive and industrial control where reliability, interoperability, and load-driving capability are jointly critical.

FAQ
What is the maximum supply voltage for MC74ACT08NG?
The absolute maximum DC supply voltage for MC74ACT08NG is +6.5 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Operating outside this range may cause undefined logic behavior or accelerated parametric drift. The MC74ACT08NG is not rated for 3.3 V operation - use MC74AC08NG instead for dual-voltage systems.
Does MC74ACT08NG support direct connection to 74LS-series TTL outputs?
Yes, MC74ACT08NG has TTL-compatible inputs with VIH(min) = 2.0 V and VIL(max) = 0.8 V at VCC = 4.5–5.5 V, matching standard 74LS logic thresholds. This allows direct, unbuffered interfacing with 74LS00, 74LS08, and similar families without level-shifting circuitry.
Is MC74ACT08NG pin-compatible with MC74AC08NG?
Yes, MC74ACT08NG and MC74AC08NG share identical pinout, package (SOIC-14), and logic function. However, MC74AC08NG uses CMOS-compatible inputs (VIH = 3.15 V min at 4.5 V), while MC74ACT08NG uses TTL-compatible inputs - so substitution requires verification of upstream driver logic levels.
What is the thermal resistance (θJA) of MC74ACT08NG in SOIC-14 package?
The junction-to-ambient thermal resistance (θJA) for MC74ACT08NG in SOIC-14 package is 116°C/W under standard JEDEC test conditions (JESD51-7). This value assumes a 1-inch² copper pad with two vias; actual board layout significantly impacts real-world thermal performance.
Where is the GND and VCC pin located on MC74ACT08NG?
On MC74ACT08NG in SOIC-14 package, Pin 7 is GND and Pin 14 is VCC - consistent with industry-standard 14-pin logic IC orientation. Pin 1 is located at the top-left corner adjacent to the index notch or dot marking, with pins numbered counter-clockwise.
