Product details
Overview
74AHCT1G02GV-Q100 from Nexperia is a single 2-input NOR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from −40 °C to +125 °C with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5.5 V supply tolerance, and overvoltage-tolerant inputs up to 5.5 V-enabling mixed-voltage logic interfacing in body control modules.
For engineers reviewing the 74AHCT1G02GV-Q100 datasheet, 74AHCT1G02GV-Q100 pinout, 74AHCT1G02GV-Q100 application, or 74AHCT1G02GV-Q100 equivalent, key selection criteria include TTL-level input compatibility, automotive temperature range compliance, SC-74A (SOT753) package footprint, and propagation delay ≤7.0 ns at 5 V/50 pF load.
Technical Context
This device implements a single 2-input NOR logic function with symmetrical output impedance and balanced propagation delays (tPLH ≈ tPHL), ensuring predictable timing behavior in combinatorial logic paths. Its TTL-level input thresholds enable direct interface with legacy 5 V microcontrollers and sensors without level-shifting.
The SC-74A (SOT753) package supports high-density PCB layouts with 5-terminal surface-mount configuration, and overvoltage-tolerant inputs simplify integration into systems with varying rail voltages-e.g., connecting 3.3 V logic outputs to this 5 V-tolerant gate input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate; implements Y = NOT(A OR B) with true combinatorial output behavior. |
| Supply Voltage Range | 4.5 V to 5.5 V; ensures stable operation across automotive battery variations including cold-crank transients. |
| Input Thresholds | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V-guarantees interoperability with standard 5 V TTL outputs. |
| Propagation Delay | ≤7.0 ns (max) at VCC = 5.0 V, CL = 50 pF; enables use in sub-100 MHz synchronous logic timing paths. |
| Output Drive | ±8.0 mA at VCC = 4.5 V; sufficient to drive multiple 74-series inputs or small capacitive loads without buffering. |
| Operating Temperature | −40 °C to +125 °C ambient; qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; meets automotive robustness requirements for handling and assembly environments. |
Pinout & Package
SC-74A (SOT753) plastic surface-mounted package: 5-terminal, leadless outline with 1.1 mm × 0.9 mm body size and 0.65 mm pitch; optimized for automated placement and reflow soldering in automotive PCB assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input B | Active-HIGH TTL-compatible input; accepts 0–5.5 V signals with overvoltage tolerance. |
| 2 (A) | Data input A | Active-HIGH TTL-compatible input; identical electrical characteristics to Pin 1. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance connection to system ground plane. |
| 4 (Y) | Data output Y | NOR logic result (Y = NOT(A OR B)); CMOS push-pull output capable of sourcing/sinking ±8 mA. |
| 5 (VCC) | Supply voltage | Primary power rail (4.5–5.5 V); decoupling capacitor (100 nF) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across −40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| TTL-level input compatibility | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply-eliminates need for external level shifters when interfacing with legacy 5 V controllers. |
| Overvoltage-tolerant inputs | Withstands up to 5.5 V regardless of VCC level-supports mixed-voltage domain translation (e.g., 3.3 V MCU driving 5 V-tolerant input). |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces signal distortion on transmission lines. |
| Low dynamic power dissipation | CPD = 19 pF; enables <1 μW static power at 1 MHz toggle rate-critical for always-on vehicle subsystems. |
Applications
| Body Control Module (BCM) | Powertrain Control Unit (PCU) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G02GW-Q100 | TSSOP5 (SOT353-1) package: 2.2 mm body width vs. 1.1 mm for SC-74A; 0.65 mm pitch identical. | Higher thermal resistance (Ptot derates above 74 °C vs. 85 °C for SC-74A); less suitable for high-power-density under-hood layouts. | Select when board space allows larger footprint and existing TSSOP5 placement tooling is in use. |
| 74AHCT1G02GZ-Q100 | XSON5 (SOT8065-1) package: 1.1 × 0.85 × 0.5 mm, side-wettable flanks, no leads-requires specialized solder inspection. | Lower thermal resistance (derates above 72 °C); superior for ultra-compact, thermally constrained modules like radar ECU edge nodes. | Select when minimizing PCB area is critical and AOI/X-ray inspection capability exists for leadless packages. |
Compared with 74AHCT1G02GV-Q100, the GW variant trades thermal performance for broader placement compatibility, while the GZ variant maximizes density at the cost of assembly complexity-making GV the optimal balance for mainstream automotive PCBs requiring proven manufacturability and thermal margin.

FAQ
Is 74AHCT1G02GV-Q100 compatible with 3.3 V microcontroller outputs?
Yes-its overvoltage-tolerant inputs accept 0–5.5 V signals regardless of VCC level, allowing direct connection to 3.3 V GPIOs without level shifters. However, output swing remains rail-to-rail (0 V to VCC), so interfacing with 3.3 V receivers requires VCC = 3.3 V or use of a compatible buffer.
What is the maximum capacitive load this gate can drive reliably?
At VCC = 5.0 V, it drives up to 50 pF with guaranteed tpd ≤7.0 ns and VOL ≤0.55 V. For loads >50 pF, propagation delay increases linearly and output voltage margins degrade-add a buffer stage if driving >75 pF or long PCB traces (>5 cm).
Does this device require external pull-up or pull-down resistors on unused inputs?
No-unused inputs must be tied HIGH or LOW to prevent floating states that cause excessive ICC and potential oscillation. The datasheet specifies VIH/VIL thresholds; tying to VCC or GND satisfies this. Pull-up/down resistors are unnecessary and add noise susceptibility.
How does its AEC-Q100 Grade 1 qualification differ from Grade 0?
Grade 1 certifies operation from −40 °C to +125 °C ambient, covering most engine bay and cabin locations. Grade 0 extends to +150 °C and adds extra thermal shock cycles-required only for extreme under-hood placements like near turbochargers or exhaust manifolds.
