Product details
Overview
MC74AC08DR2 from onsemi is a quad 2-input AND gate in high-performance silicon-gate CMOS technology, operating at 2.0–6.0 V supply voltage, delivering ±24 mA output drive, with propagation delay as low as 5.5 ns at 5.0 V and 50 pF load, used for digital logic level translation and signal gating in industrial control and automotive body electronics.
For engineers reviewing the MC74AC08DR2 datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-14), confirmed DC/AC electrical specs, AEC-Q100 qualification status, thermal resistance (116 °C/W), and functional alternatives for logic-level AND gate replacement.
Technical Context
This device implements four independent 2-input AND gates using AC-series CMOS logic, supporting rail-to-rail input voltage range (0 to VCC) and guaranteed TTL-compatible output levels across −40°C to +85°C ambient. It features no internal Schmitt-trigger inputs and operates without latch-up up to 100 mA injected current at 85°C.
The MC74AC08DR2 uses standard positive-logic AND truth table behavior per gate, with input thresholds defined at 30%/70% of VCC for rise/fall timing measurements, and exhibits 4.5 pF typical input capacitance and 20 pF power-dissipation capacitance at 5.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - enables four independent Boolean conjunction operations in one package |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing including 3.3 V and 5 V domains |
| Output Drive | ±24 mA - sufficient to directly drive LED indicators, small-signal MOSFET gates, or TTL inputs |
| Propagation Delay | 5.5 ns max at 5.0 V / 50 pF - ensures timing-critical combinational logic paths meet sub-10 ns budgets |
| Input Thresholds | VIH = 2.1 V min, VIL = 0.9 V max at VCC = 3.0 V - provides noise margin >0.6 V under nominal 3.3 V operation |
| Quiescent ICC | 40 µA max at 5.5 V - enables low-static-power operation in battery-backed or always-on subsystems |
| ESD Rating | >2000 V HBM - meets industrial IEC 61000-4-2 Level 2 immunity requirements without external protection |
Pinout & Package
MC74AC08DR2 is housed in a Pb-free SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.55–8.75 mm body width, and 1.35–1.75 mm height. Thermal resistance is 116 °C/W in still air.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Input A/B per gate | Eight total inputs - two per AND gate (Gates 1–4); all accept 0–VCC logic levels |
| 3, 6, 10, 11 | Output Y per gate | Four buffered AND outputs - each capable of sourcing/sinking ±24 mA continuously |
| 7 | GND | Ground reference for all logic and power domains; must be low-impedance connection |
| 14 | VCC | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free SOIC-14 packaging | Complies with RoHS Directive 2011/65/EU and J-STD-020 moisture sensitivity Level 1 |
| AEC-Q100 qualified (−Q variant) | Validated for automotive applications including body control modules and lighting controllers |
| High noise immunity | Input hysteresis not present, but VIH/VIL margins exceed 30% of VCC across full temperature range |
| Low dynamic power consumption | CPD = 20 pF enables <1 mW average power at 1 MHz toggle rate and 5 V supply |
| Robust ESD protection | HBM >2000 V and CDM >1000 V reduce need for board-level transient suppression |

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 |
|---|---|---|---|
| SN74AC08DR | Same AC logic family, identical SOIC-14 pinout, but TI-specified VCC range 2.0–6.0 V and VOH = 4.4 V min at 5 V/−24 mA (vs. onsemi's 4.4 V min) | No AEC-Q100 qualification; rated for commercial temperature only (0°C to 70°C) | Select SN74AC08DR where automotive qualification is unnecessary and TI supply chain preference applies. |
| 74VHC08M | Higher speed (tPD = 4.5 ns typ), lower ICC (2 µA max), but narrower VCC range (2.0–5.5 V) and no AEC-Q100 certification | Not qualified for automotive use; lacks PPAP documentation support for Tier 1 OEM programs | Choose 74VHC08M when sub-5 ns propagation is critical and extended temperature operation is not required. |
Compared with MC74AC08DR2, SN74AC08DR offers identical logic behavior and footprint but omits automotive qualification, while 74VHC08M delivers faster timing at the cost of reduced supply headroom and no AEC-Q100 validation-making MC74AC08DR2 the sole option meeting both performance and automotive compliance requirements.

FAQ
What is the maximum operating temperature for MC74AC08DR2?
The MC74AC08DR2 is specified for operation from −40°C to +85°C ambient temperature. Its junction temperature must remain ≤150°C under bias, and thermal resistance (θJA) is 116 °C/W in SOIC-14 package. Derating is required above 70°C ambient if power dissipation exceeds 10 mW per gate.
Does MC74AC08DR2 support 3.3 V logic systems?
Yes, MC74AC08DR2 fully supports 3.3 V operation: its recommended VCC range includes 3.0 V minimum, VIH is guaranteed ≥1.5 V at 3.0 V, and VOH reaches ≥2.9 V at −24 mA load - providing >0.6 V noise margin against 3.3 V LVTTL thresholds.
Is MC74AC08DR2 pin-compatible with MC74ACT08DR2G?
No, MC74AC08DR2 is not pin-compatible with MC74ACT08DR2G in terms of input interface behavior: although both share identical SOIC-14 pinout and logic function, the ACT version has TTL-compatible inputs (VIH = 2.0 V min at 4.5 V), while AC version uses CMOS thresholds (VIH = 2.1 V min at 3.0 V). Interchange requires verification of source driver compatibility.
What does the "−Q" suffix mean in MC74AC08DR2G−Q*?
The "−Q" suffix in MC74AC08DR2G−Q* denotes AEC-Q100 qualification and PPAP capability for automotive applications, with unique site and control change requirements. The base part MC74AC08DR2G (without −Q) is identical in electrical and mechanical specs but lacks automotive-specific process controls and documentation.
Can MC74AC08DR2 drive a 50 Ω transmission line directly?
No, MC74AC08DR2 cannot directly drive a 50 Ω transmission line: its output impedance is ~20 Ω (derived from 24 mA drive into 0.44 V VOL), resulting in significant reflection and overshoot on 50 Ω lines. A series termination resistor (~30 Ω) or dedicated line-driver buffer is required for clean signal integrity.
