Product details
Overview
74HCT2G02DC-Q100 from Nexperia is a dual 2-input NOR gate in VSSOP8 package, qualified to AEC-Q100 Grade 1 for automotive use. It operates from 4.5 V to 5.5 V, accepts TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V), delivers CMOS-level outputs, and exhibits propagation delay of 12 ns (typ) at VCC = 4.5 V with 15 pF load - enabling reliable logic inversion and signal conditioning in engine control units.
For engineers reviewing the 74HCT2G02DC-Q100 datasheet, 74HCT2G02DC-Q100 pinout, 74HCT2G02DC-Q100 application, or 74HCT2G02DC-Q100 equivalent, key selection criteria include its automotive qualification, TTL-compatible input thresholds, dual-gate integration in space-constrained VSSOP8, and guaranteed operation from –40 °C to +125 °C ambient.
Technical Context
This device implements two independent 2-input NOR gates using silicon-gate CMOS technology. Each gate performs Boolean logic: output is HIGH only when both inputs are LOW; all other input combinations yield LOW output. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
The 74HCT variant specifically adapts input threshold levels to match legacy TTL families: VIH(min) = 2.0 V and VIL(max) = 0.8 V at VCC = 4.5–5.5 V, ensuring robust noise margin and compatibility with 5 V TTL outputs while maintaining CMOS output drive strength and low static power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input NOR: each gate outputs HIGH only if both inputs are LOW |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive rail with ±10% tolerance |
| Input Thresholds | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures interoperability with legacy 5 V TTL drivers |
| Propagation Delay | 12 ns (typ) at VCC = 4.5 V, CL = 15 pF - supports >30 MHz toggle rates in combinatorial logic paths |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or moderate capacitive bus lines |
| Input Clamp Diodes | Integrated - enables safe interface to signals up to VCC + 0.5 V using external current-limiting resistors |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First NOR gate input A - accepts TTL/CMOS logic levels; protected by clamp diode |
| 2 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor |
| 3 | 1B | First NOR gate input B - electrically identical to Pin 1; supports same voltage interface rules |
| 4 | 1Y | First NOR gate output - drives CMOS-compatible loads; VOH ≥ 4.13 V at IO = –4.0 mA |
| 5 | 2Y | Second NOR gate output - independent of first gate; shares no internal nodes |
| 6 | 2B | Second NOR gate input B - fully isolated from 1A/1B; identical electrical characteristics |
| 7 | GND | Ground reference - must connect to low-impedance system ground plane for noise immunity |
| 8 | 2A | Second NOR gate input A - pinout symmetry allows PCB layout mirroring for routing efficiency |
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 HTRB |
| TTL-level input compatibility | VIH(min) = 2.0 V and VIL(max) = 0.8 V at 4.5–5.5 V supply - eliminates level-shifter need in mixed-logic systems |
| Input clamp diodes | Enable safe interface to overvoltage signals (e.g., sensor outputs) when paired with series current-limiting resistors |
| Low dynamic power | CPD = 10 pF - limits switching power dissipation to <1 mW at 1 MHz with 15 pF load and 5 V supply |
| High noise immunity | Typical noise margin >1.2 V at VCC = 5 V - suppresses false triggering from EMI in engine bay environments |
Applications
| Engine Control Unit (ECU) Safety Logic | Body Control Module (BCM) Signal Conditioning |
|---|---|
Use Scenario: Detecting simultaneous fault conditions (e.g., brake pedal + accelerator pressed) to trigger fail-safe shutdown. IC Role / Device Role / Timing Role: Dual NOR gate implements active-low combinational logic: only asserts safety interrupt when both inputs are LOW (no faults). Use Value: Eliminates need for discrete diode-resistor networks; provides deterministic propagation delay (<29 ns max) for time-critical fault response. | Use Scenario: Debouncing and synchronizing mechanical switch inputs (e.g., door lock/unlock buttons) before microcontroller sampling. IC Role / Device Role / Timing Role: NOR gate configured as SR latch or pulse stretcher to filter contact bounce and align edges to system clock domain. Use Value: Reduces firmware overhead for debouncing; TTL input thresholds ensure compatibility with 5 V pull-up switch interfaces. |
| Advanced Driver Assistance Systems (ADAS) Sensor Interface | Automotive Infotainment Power Sequencing |
Use Scenario: Validating redundant sensor outputs (e.g., two radar modules) to detect disagreement before triggering warning alerts. IC Role / Device Role / Timing Role: NOR gate compares inverted sensor status bits: HIGH output indicates mismatch requiring diagnostic escalation. Use Value: Provides hardware-level sensor validation with sub-30 ns latency - faster than software polling and immune to MCU lockup. | Use Scenario: Controlling power-up sequence of display controller and audio processor to prevent I²C bus contention during boot. IC Role / Device Role / Timing Role: NOR gate combines reset and enable signals to generate delayed, synchronized power-enable pulses. Use Value: Ensures strict power-rail sequencing without requiring dedicated PMIC; VSSOP8 footprint saves board space in tight infotainment head units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G02DPWR | Lower VCC range (1.65–5.5 V); CMOS inputs only (VIH = 0.7×VCC); no AEC-Q100 qualification | Targeted at industrial/commercial designs; lacks automotive temperature and reliability validation | Select when cost or wider supply flexibility outweighs automotive compliance requirements |
| 74AHC2G02DC-Q100 | Faster propagation delay (6.5 ns typ at VCC = 5 V); higher ICC (20 μA max vs. 10 μA); same AEC-Q100 Grade 1 rating | Suitable for high-speed timing-critical paths where 12 ns delay is insufficient | Choose for applications needing <7 ns delay with identical automotive qualification and pinout |
Compared with SN74LVC2G02DPWR, the 74HCT2G02DC-Q100 offers guaranteed automotive operation and TTL input compatibility but narrower supply range; versus 74AHC2G02DC-Q100, it trades speed for lower static current and cost, maintaining identical footprint and qualification.

FAQ
What is the maximum operating frequency supported by the 74HCT2G02DC-Q100?
The device does not specify a maximum clock frequency, as it is a combinational logic gate. Its usable toggle rate depends on propagation delay and load capacitance: with 15 pF load and VCC = 4.5 V, tpd = 12 ns (typ), supporting reliable operation up to ~30 MHz in feedback-free configurations. System-level timing must account for worst-case 29 ns delay at temperature extremes.
Can the 74HCT2G02DC-Q100 interface directly with 3.3 V microcontrollers?
No - the 74HCT2G02DC-Q100 requires VCC = 4.5–5.5 V and has TTL input thresholds (VIH ≥ 2.0 V). A 3.3 V MCU output may not reliably exceed VIH(min) across voltage and temperature variation. Use a level shifter or select a 3.3 V–compatible variant like 74LVC2G02DC-Q100 if interfacing with 3.3 V logic.
Does this part support hot insertion or live circuit connection?
No - the 74HCT2G02DC-Q100 is not hot-swap rated. Its absolute maximum ratings prohibit applying input signals before VCC stabilization. Always power VCC and GND before asserting any inputs, and avoid floating inputs during power transitions to prevent latch-up or excessive ICC.
How does the input clamp diode affect external resistor selection for overvoltage protection?
When interfacing to signals exceeding VCC (e.g., 12 V sensors), a series current-limiting resistor must restrict diode conduction to ≤20 mA (per Absolute Maximum Rating). For a 12 V input and VCC = 5 V, minimum resistor = (12 V − 5.5 V) / 20 mA = 325 Ω; 1 kΩ is recommended to ensure margin and reduce self-heating under continuous fault conditions.
