Product details
Overview
74HCT1G02GV-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 levels, 4.5 V to 5.5 V supply range, and propagation delay of 11 ns (typ) at VCC = 4.5 V and CL = 50 pF - used in engine control unit logic conditioning and body electronics signal inversion.
For engineers reviewing the 74HCT1G02GV-Q100 datasheet, 74HCT1G02GV-Q100 pinout, 74HCT1G02GV-Q100 application, or 74HCT1G02GV-Q100 equivalent, this page delivers verified pin functions, automotive-grade thermal and ESD specs (HBM >2000 V), real-world timing behavior, and direct substitution guidance against functional alternatives.
Technical Context
This device implements a single 2-input NOR logic function with symmetrical output impedance and balanced propagation delays between inputs A/B and output Y. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure compatibility with legacy 5 V microcontroller I/O while maintaining CMOS power efficiency.
Input clamp diodes enable safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The device supports dynamic operation up to 100 MHz (based on tpd = 11 ns and CPD = 19 pF), with static supply current under 10 μA at VCC = 5.5 V and ambient temperatures up to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate - performs Boolean Y = NOT(A OR B); used for active-low enable/disable and signal arbitration. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive rail; supports stable operation across battery voltage transients. |
| Propagation Delay | 11 ns (typ) at VCC = 4.5 V, CL = 50 pF - enables reliable timing in sub-100 MHz digital control loops. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures robust noise margin (>0.4 V) against TTL-compatible drivers in noisy vehicle environments. |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets automotive assembly and handling requirements without additional protection circuitry. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| Output Drive | ±2.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF). |
Pinout & Package
74HCT1G02GV-Q100 uses the SC-74A (SOT753) surface-mount package: plastic, 5-terminal, 1.1 mm × 1.7 mm body, 0.65 mm lead pitch, and gull-wing leads. Pin 1 (input B) is marked by a notch or dot adjacent to the marking "T02".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second logic input - accepts TTL-level signals; clamped to GND/VCC via internal diodes for overvoltage tolerance. |
| 2 | A | Primary logic input - identical electrical characteristics to Pin 1; both inputs fully interchangeable. |
| 3 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling into logic threshold. |
| 4 | Y | Inverted OR output - sinks or sources up to ±2.0 mA; output swing within 0.15 V of rails under rated load. |
| 5 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C with lifetime reliability testing per stress conditions defined in AEC standard. |
| TTL-compatible input levels | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply - eliminates level-shifting when interfacing with legacy 5 V MCUs and sensors. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces signal skew in timing-critical paths. |
| Input clamp diodes | Enable safe interface to voltages up to VCC + 0.5 V using external current-limiting resistors - simplifies mixed-voltage subsystem design. |
| Low static power consumption | ICC ≤ 10 μA at VCC = 5.5 V and Tamb = 25 °C - supports always-on modules with strict quiescent current budgets. |

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 |
|---|---|---|---|
| 74HCT1G02GW-Q100 | TSSOP5 (SOT353-1) package: 1.25 mm body width, 0.65 mm pitch, higher thermal resistance (3.3 mW/K derating above 74 °C). | Better suited for PCBs with larger trace spacing and manual rework access; slightly lower power dissipation margin at high ambient. | Select when board layout allows wider pitch and thermal management prioritizes package visibility over footprint size. |
| 74HCT1G02GZ-Q100 | XSON5 (SOT8065-1) package: 1.1 × 0.85 × 0.5 mm, side-wettable flanks, no leads, 3.2 mW/K derating above 72 °C. | Optimized for automated optical inspection (AOI) and high-density automotive modules where space and thermal performance are critical. | Select for compact ADAS ECUs requiring IPC Class 3 solder joint reliability and minimal board area usage. |
Compared with 74HCT1G02GV-Q100, the GW variant trades smaller footprint for easier reworkability, while the GZ variant maximizes thermal density and AOI compatibility - all three share identical logic behavior, AEC-Q100 Grade 1 qualification, and TTL input thresholds.

FAQ
What is the maximum clock frequency supported by 74HCT1G02GV-Q100?
The device does not operate as a clocked element but as combinational logic. Its usable signal frequency depends on propagation delay and load capacitance. With tpd = 11 ns (typ) and CL = 50 pF, it reliably supports data rates up to ~100 MHz in toggle-mode operation, assuming proper PCB layout and supply decoupling.
Can 74HCT1G02GV-Q100 interface directly with 3.3 V microcontrollers?
No - its TTL input thresholds require VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V, making it incompatible with 3.3 V logic without level translation. For 3.3 V systems, consider the 74LVC1G02GV-Q100, which supports 1.65–5.5 V supply and 3.3 V-compatible inputs.
Does this part include Schmitt-trigger inputs?
No - the 74HCT1G02GV-Q100 has standard TTL-compatible CMOS inputs without hysteresis. It lacks Schmitt-trigger behavior; input transition thresholds are fixed at ~1.3 V (VM), so external noise filtering is recommended in electrically noisy automotive environments.
Is the SC-74A (SOT753) package RoHS and REACH compliant?
Yes - Nexperia confirms the SOT753 package used for 74HCT1G02GV-Q100 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including exemption 7a for lead in high-melting-temperature type solders, and is halogen-free per IEC 61249-2-21.
