Product details
Overview
74AHC2G08DC-Q100 from Nexperia is a dual 2-input AND gate in VSSOP8 package, qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0–5.5 V, overvoltage-tolerant inputs up to 5.5 V, and CMOS-level input compatibility. It performs logic gating in body control modules, infotainment power sequencing, and sensor signal conditioning.
For engineers reviewing the 74AHC2G08DC-Q100 datasheet, 74AHC2G08DC-Q100 pinout, 74AHC2G08DC-Q100 application, or 74AHC2G08DC-Q100 equivalent, this page delivers verified pin functions, automotive-grade thermal and voltage specs, propagation delay values at 15 pF/50 pF loads, static VIH/VIL thresholds, and direct alternatives with TTL/CMOS input logic differentiation.
Technical Context
This device implements two independent AND logic gates in a single monolithic CMOS silicon die. Each gate accepts two digital inputs (1A/1B, 2A/2B), produces one output (1Y/2Y), and shares common VCC and GND terminals. Input structure supports overvoltage tolerance up to 5.5 V regardless of VCC level, enabling mixed-voltage interfacing between 3.3 V and 5 V domains.
Propagation delays are tightly balanced across channels (tpd ≤ 8.0 ns at VCC = 5.0 V, CL = 15 pF) and symmetrically matched between rising/falling edges (tPLH ≈ tPHL). Static characteristics include VIH = 3.85 V min at VCC = 5.5 V and VOL = 0.55 V max at IO = 8.0 mA, ensuring robust noise margins in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input AND gates - enables compact dual-gate logic without external interconnect |
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct interface with 2.5 V, 3.3 V, and 5 V microcontrollers and peripherals |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and powertrain applications per AEC-Q100 Grade 1 |
| Propagation Delay | ≤ 8.0 ns at VCC = 5.0 V, CL = 15 pF - ensures timing-critical signal combing in ADAS sensor fusion paths |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe connection to higher-voltage buses without level shifters |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS inputs or small capacitive loads directly |
| Power Dissipation | 250 mW max at Tamb ≤ 125 °C - derates linearly above 99 °C (4.9 mW/K) for thermal design margin |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8 leads, 2.3 mm body width, 0.65 mm pitch, pin 1 index in lower-left corner below marking code "A08".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First gate input A - accepts logic HIGH/LOW signals; overvoltage tolerant to 5.5 V |
| 2 | 1B | First gate input B - paired with 1A for AND operation; identical electrical behavior to 1A |
| 3 | 2Y | Second gate output Y - drives downstream logic; VOH ≥ 3.70 V at IO = −8.0 mA, VCC = 4.5 V |
| 4 | GND | Ground reference - must be low-impedance connection to system 0 V plane for noise immunity |
| 5 | 2A | Second gate input A - electrically isolated from first gate; supports independent logic paths |
| 6 | 2B | Second gate input B - complements 2A; no internal coupling to 1A/1B pins |
| 7 | 1Y | First gate output Y - active-HIGH AND result; VOL ≤ 0.55 V at IO = 8.0 mA, VCC = 4.5 V |
| 8 | VCC | Positive supply - powers both gates; decoupling capacitor (100 nF) required within 10 mm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including temperature cycling and HTOL stress |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals regardless of VCC setting - eliminates need for external level translators |
| CMOS input threshold (74AHC variant) | VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max - provides >1.5 V noise margin at 5 V operation |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures equal rise/fall times and reduces EMI in high-speed switching |
| Low dynamic power consumption | CPD = 17 pF per buffer - limits switching power to <1 μW/MHz at 3.3 V, critical for battery-powered ECUs |
Applications
| Body Control Module (BCM) | Infotainment Power Sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT2G08DC-Q100 | TTL-compatible inputs (VIH = 2.0 V min); same package, temp range, and pinout | Better suited for legacy 5 V TTL systems; lower input threshold increases noise susceptibility in 3.3 V domains | Select when interfacing with older microcontrollers or discrete TTL logic families |
| SN74LVC2G08QDCURQ1 | TI part with 1.65–5.5 V VCC range; LVC logic family; slightly higher ICC (max 10 μA vs 1 μA) | Broader supply range supports 1.8 V I/O domains; not AEC-Q100 Grade 1 qualified (only Grade 2) | Choose only if 1.8 V compatibility is mandatory and Grade 1 qualification is not required |
Compared with 74AHC2G08DC-Q100, the 74AHCT2G08DC-Q100 offers TTL input compatibility at the cost of reduced noise immunity, while SN74LVC2G08QDCURQ1 extends voltage range downward but sacrifices automotive Grade 1 reliability assurance and increases quiescent current by 10×.

FAQ
Is 74AHC2G08DC-Q100 pin-compatible with 74AHCT2G08DC-Q100?
Yes - both share identical VSSOP8 (SOT765-1) packaging, pin numbering, and terminal functions. The only functional difference is input logic threshold: 74AHC2G08DC-Q100 uses CMOS-compatible VIH/VIL, while 74AHCT2G08DC-Q100 uses TTL-compatible thresholds. No PCB redesign is needed for substitution.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies guaranteed timing performance up to 50 pF load capacitance (tpd ≤ 10.5 ns at VCC = 5.0 V). Driving >50 pF may increase propagation delay nonlinearly and degrade edge rate; for >100 pF loads, add a series resistor or buffer stage to maintain signal integrity.
Does this device require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied HIGH or LOW via direct connection to VCC or GND. Floating inputs cause increased ICC, unpredictable output states, and potential latch-up risk. The device has no internal termination; external biasing is mandatory for unconnected pins.
Can 74AHC2G08DC-Q100 operate at 2.0 V supply while interfacing with 5.0 V sensors?
Yes - its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC. At VCC = 2.0 V, VIH remains 1.5 V min and VIL stays 0.5 V max, allowing reliable recognition of 5 V logic HIGH/LOW signals without damage or level translation circuitry.
