Product details
Overview
74AHCT2G08DP-Q100 from Nexperia is a dual 2-input AND gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with TTL-level inputs, 2.0–5.5 V supply range, and overvoltage-tolerant inputs up to 5.5 V. It performs logic gating in powertrain control units and body electronics where mixed-voltage signal translation is required.
For engineers reviewing the 74AHCT2G08DP-Q100 datasheet, 74AHCT2G08DP-Q100 pinout, 74AHCT2G08DP-Q100 application, or 74AHCT2G08DP-Q100 equivalent, key selection criteria include input voltage compatibility (TTL), propagation delay at 5 V (≤8.0 ns @ CL=50 pF), output drive strength (±8 mA), thermal rating (-40 °C to +125 °C), and AEC-Q100 qualification status.
Technical Context
This device implements two independent AND logic functions in a single monolithic CMOS structure with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and rail-to-rail output swing. Its symmetrical output impedance ensures matched rise/fall times under load.
The architecture supports mixed-voltage interfacing via overvoltage-tolerant inputs (up to 5.5 V regardless of VCC), enabling direct connection to 3.3 V logic driving 5 V subsystems without level shifters. Propagation delays are balanced across both gates (tpd ≤ 8.0 ns @ VCC = 5.0 V, CL = 50 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input AND gate - provides two independent Boolean AND operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with standard 5 V automotive rails and tolerant of ripple and transients |
| Propagation Delay | ≤8.0 ns @ VCC = 5.0 V, CL = 50 pF - enables timing-critical control loops in engine management systems |
| Output Drive | ±8.0 mA @ VCC = 4.5 V - sufficient to drive multiple CMOS inputs or small capacitive loads directly |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches legacy TTL logic families for seamless integration |
| Operating Temperature | -40 °C to +125 °C - meets under-hood automotive ambient requirements per AEC-Q100 Grade 1 |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - ensures robustness during PCB handling and in-vehicle ESD events |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 indicator located on lower left corner below marking code 'C08'.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First AND gate input A - accepts TTL-level signals; overvoltage tolerant to 5.5 V |
| 2 | 1B | First AND gate input B - electrically identical to Pin 1; enables dual-input logic evaluation |
| 3 | 2Y | Second AND gate output Y - delivers rail-to-rail CMOS output compatible with downstream 5 V logic |
| 4 | GND | Ground reference - must be low-impedance connection to minimize noise coupling between gates |
| 5 | 2A | Second AND gate input A - isolated from first gate; supports independent logic path routing |
| 6 | 2B | Second AND gate input B - paired with Pin 5 to form second AND function; shares same VIH/VIL specs |
| 7 | 1Y | First AND gate output Y - outputs HIGH only when both Pins 1 and 2 are HIGH; drives fanout ≤10 |
| 8 | VCC | Positive supply - powers both gates; decoupling capacitor (100 nF) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive applications requiring operation from -40 °C to +125 °C ambient |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC setting - eliminates need for external level translators |
| Matched propagation delays | tpLH and tpHL differ by <10% - critical for synchronous logic in safety-critical control paths |
| Low dynamic power dissipation | CPD = 19 pF per buffer - reduces switching current and thermal load in high-frequency enable/disable circuits |
| High noise immunity | Input hysteresis not present, but VIH/VIL margins exceed 0.7 V at 5 V - suppresses false triggering |
Applications
| Powertrain Control Unit | Body Control Module |
|---|---|

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 | VSSOP8 package (2.3 mm body width); identical electrical specs and AEC-Q100 qualification | Higher board density requirement; tighter layout constraints due to smaller pitch and exposed pad absence | Select when PCB space is constrained and thermal load is low (<15 mW per gate) |
| SN74LVC2G08QDCURQ1 | Lower VCC range (1.65–5.5 V); CMOS input thresholds; higher ICC (max 10 μA vs. 40 μA at 125 °C) | Supports 1.8 V logic domains; unsuitable for pure 5 V TTL interface without external pull-ups | Select only when interfacing with mixed 1.8/3.3/5 V subsystems and AEC-Q100 Grade 1 is confirmed for that variant |
Compared with 74AHCT2G08DP-Q100, the DC variant offers footprint reduction but sacrifices thermal margin in high-power-density layouts, while the TI part enables broader voltage interoperability at the cost of TTL compatibility and verified automotive qualification scope.

FAQ
What is the maximum allowable input voltage on pins 1, 2, 5, and 6 when VCC = 3.3 V?
The 74AHCT2G08DP-Q100 features overvoltage-tolerant inputs rated to 5.5 V regardless of VCC level. When VCC = 3.3 V, inputs may safely accept signals up to 5.5 V without damage or latch-up, enabling direct interfacing with 5 V microcontrollers or sensors without level-shifting circuitry.
Does this device support hot insertion or live swapping in powered systems?
No. While the device has robust ESD protection (HBM > 2000 V), it lacks explicit hot-swap circuitry such as power-on reset, slew-rate controlled I/O, or back-drive protection. Applying input signals before VCC stabilization may cause undefined output states or increased ICC; power sequencing per datasheet Section 9 is required.
Can both AND gates be used independently with different supply voltages?
No. The device has a single VCC pin (Pin 8) and shared ground (Pin 4). Both gates operate from the same supply rail; split-rail or dual-supply configurations are not supported. Mixed-voltage operation is achieved solely through overvoltage-tolerant inputs, not separate VCC domains.
What is the recommended PCB layout practice for minimizing propagation delay skew between the two gates?
Route input traces for Gate 1 (Pins 1,2) and Gate 2 (Pins 5,6) with matched lengths and identical topology. Place decoupling capacitor (100 nF X7R) within 5 mm of Pin 8 (VCC) and connect to Pin 4 (GND) with shortest possible trace. Avoid crossing sensitive input/output pairs to prevent crosstalk-induced timing jitter.
