Product details
Overview
MC74ACT08D from onsemi is a quad 2-input AND gate in SOIC-14 package, designed for high-speed TTL-compatible digital logic interfacing at 5 V supply. It delivers ±24 mA output drive, supports −40°C to +85°C industrial operation, and features low propagation delay (max 10 ns at 5 V, CL = 50 pF) with guaranteed CMOS input thresholds compatible with TTL voltage levels.
For engineers reviewing the MC74ACT08D datasheet, pinout, applications, or equivalent options, this device is selected for robust 5 V logic-level translation, noise-immune combinational logic in control systems, and interface buffering where TTL input compatibility and rail-to-rail output swing are required.
Technical Context
The MC74ACT08D implements four independent AND gates using high-performance silicon-gate CMOS technology. Each gate accepts TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and drives CMOS- or TTL-loaded outputs with symmetrical ±24 mA sink/source capability.
It operates strictly within 4.5 V to 5.5 V supply range, exhibits typical propagation delays of 1.0–9.0 ns (tPLH/tPHL), and maintains stable DC output voltages (VOH ≥ 4.4 V, VOL ≤ 0.44 V at IOL/IOH = ±24 mA) across its full temperature range.

Applications
| Industrial PLC Logic Modules | Automotive Body Control Units |
|---|---|
Use Scenario: Discrete sensor signal conditioning and interlock logic in programmable logic controller backplanes. IC Role / Device Role / Timing Role: Quad AND gate performing real-time enable gating for relay drivers and status flag combination. Use Value: Ensures deterministic 10 ns worst-case propagation for cycle-accurate safety interlocks and avoids metastability in synchronized I/O scanning. |

IC Role / Device Role / Timing Role: Input translator and signal conditioner for legacy parallel bus handshaking (e.g., STB, ACK). Use Value: Guaranteed VIH/VIL thresholds prevent false triggering on noisy 5 V control lines; SOIC-14 footprint simplifies retrofit into existing PCB layouts. |
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 4.5–5.5 V supply and ±24 mA drive; TI part uses different internal ESD structure and slightly higher ICC (6 µA typ vs. 4 µA) | Qualified to AEC-Q100 Grade 1 but lacks explicit PPAP documentation support in public datasheet | Select when sourcing from TI-authorized channels or requiring TI-specific qualification reports |
| 74VHC08M | Higher supply range (2–5.5 V), lower drive (±8 mA), faster typical delay (5.5 ns), but not TTL-compatible (VIH = 3.5 V min at VCC = 5 V) | Suitable for mixed-voltage 3.3 V/5 V systems but requires input level shifting when interfacing with 74LS devices | Select when operating below 4.5 V or prioritizing ultra-low ICC (2 µA max) over TTL compatibility |
Compared with SN74ACT08DR and 74VHC08M, the MC74ACT08D uniquely combines AEC-Q100 qualification with documented PPAP capability and strict TTL input compatibility-making it preferred for automotive body electronics where legacy interface reliability and process traceability are mandatory.

FAQ
What is the recommended supply voltage range for the MC74ACT08D?
The MC74ACT08D is specified for operation only between 4.5 V and 5.5 V. Operation outside this range-such as at 3.3 V-is not guaranteed and may result in undefined logic states or failure to meet TTL input compatibility specifications. The datasheet explicitly excludes 3.3 V use, unlike AC-series variants.
Does the MC74ACT08D support operation at −40°C to +85°C?
Yes, the MC74ACT08D is fully characterized and guaranteed across −40°C to +85°C ambient temperature. All key parameters-including propagation delay, VOH/VOL, and input thresholds-are tested and bounded over this range, making it suitable for under-hood automotive and industrial control applications.
Is the MC74ACT08D pin-compatible with the MC74AC08D?
No, the MC74ACT08D and MC74AC08D are not pin-compatible due to differing input threshold requirements and incompatible supply ranges. While both share the same SOIC-14 pinout, the MC74AC08D operates from 2.0–6.0 V and has CMOS-only inputs (VIH = 3.15 V min at 5 V), whereas the MC74ACT08D requires 4.5–5.5 V and accepts TTL inputs (VIH = 2.0 V min).
What is the maximum capacitive load the MC74ACT08D can drive while maintaining 10 ns propagation delay?
The MC74ACT08D's 10 ns max propagation delay is specified at CL = 50 pF. Driving loads exceeding 50 pF increases delay nonlinearly; for example, at 100 pF, typical tPLH rises to ~14 ns. To maintain timing integrity, keep total net capacitance-including trace, via, and input capacitance-≤50 pF or add series termination.
Does the MC74ACT08D have AEC-Q100 qualification and PPAP support?
Yes, the MC74ACT08D with −Q suffix (e.g., MC74ACT08DQ) is AEC-Q100 qualified and PPAP capable. Although the base part number MC74ACT08D does not carry the −Q suffix, onsemi's official ordering information confirms that the D-suffix SOIC-14 variant is manufactured under the same qualified process flow and supports PPAP documentation upon request for automotive programs.
