Product details
Overview
74HCT1G02GW-Q100 from Nexperia is an automotive-qualified single 2-input NOR gate in TSSOP5 (SOT353-1) package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, propagation delay of 11 ns (typ) at VCC = 4.5 V and CL = 50 pF, and AEC-Q100 Grade 1 qualification (-40 °C to +125 °C). It serves as a logic-level combinatorial gate in vehicle body control modules, sensor interface signal conditioning, and power management sequencing circuits.
For engineers reviewing the 74HCT1G02GW-Q100 datasheet, 74HCT1G02GW-Q100 pinout, 74HCT1G02GW-Q100 application, or 74HCT1G02GW-Q100 equivalent, this page delivers verified electrical parameters, automotive-grade thermal and ESD specifications, functional pin mapping for TSSOP5, real-world use cases in automotive subsystems, and validated alternative parts with precise technical and application-level distinctions.
Technical Context
This device implements standard positive-logic NOR functionality (Y = NOT(A OR B)) using CMOS technology with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V microcontrollers and ASICs. Input clamp diodes allow safe overvoltage tolerance when used with current-limiting resistors.
It features symmetrical output drive capability (±2.0 mA at VCC = 4.5 V), balanced propagation delays (tPLH ≈ tPHL), and low static current (ICC ≤ 20 μA at VCC = 5.5 V, -40 °C to +125 °C), making it suitable for always-on automotive domains requiring predictable timing and minimal quiescent power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate: Y = NOT(A OR B); enables basic combinatorial logic in compact space-constrained nodes. |
| Supply Voltage Range | 4.5 V to 5.5 V (recommended); ensures compatibility with standard 5 V automotive rails and stable operation across load dump transients. |
| Propagation Delay | 11 ns (typ) at VCC = 4.5 V, CL = 50 pF; supports sub-100 MHz logic timing in control path synchronization. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max (TTL-compatible); eliminates need for level shifters when interfacing with 5 V MCU GPIOs. |
| Output Drive | ±2.0 mA (IOH/ IOL) at VCC = 4.5 V; sufficient to drive multiple 74-series inputs or small capacitive loads (< 30 pF) without buffering. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; meets automotive board-level robustness requirements without external protection components. |
| Ambient Temperature | -40 °C to +125 °C; qualified per AEC-Q100 Grade 1 for under-hood and cabin control unit deployment. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input | Standard CMOS/TTL input with clamp diodes; accepts voltages up to VCC + 0.5 V when current-limited. |
| 2 (A) | Data input | Identical to Pin 1; dual-input symmetry allows flexible PCB routing and logic inversion reuse. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance connection to minimize noise coupling. |
| 4 (Y) | Data output | Push-pull CMOS output capable of sourcing/sinking ±2.0 mA; compatible with 50 Ω transmission lines at low frequencies. |
| 5 (VCC) | Supply voltage | Primary power rail; requires local 100 nF ceramic decoupling within 5 mm of pin for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling, humidity, and mechanical shock tests. |
| TTL-compatible input levels | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply enables plug-in replacement of legacy 74LS series gates without redesign. |
| Symmetrical output impedance | Matched rise/fall times (tPLH ≈ tPHL) reduce signal skew in timing-critical paths such as clock enable or reset assertion. |
| Input clamp diodes | Allow safe interface to signals exceeding VCC (e.g., 12 V sensor outputs) when used with series current-limiting resistors ≥ 10 kΩ. |
| Low ICC and CI | ICC ≤ 20 μA and CI = 1.5 pF minimize power and capacitive loading in battery-backed or low-power wake-up circuits. |
Applications
| Body Control Module (BCM) | Door Module Logic |
|---|---|
|
Use Scenario: Combining door open/closed and window position signals to generate lock-enable logic only when doors are fully closed and windows are up. IC Role / Device Role / Timing Role: Combinatorial gate performing real-time NOR of two safety-critical sensor inputs before enabling actuator driver. Use Value: Eliminates need for microcontroller polling or software logic, reducing latency (<15 ns) and firmware complexity in ASIL-B-relevant functions. |
Use Scenario: Generating anti-pinch disable signal by NOR-ing motor current sense fault and timeout counter overflow outputs. IC Role / Device Role / Timing Role: Hardware-level fault masking gate ensuring immediate hardware cutoff on dual-fault detection, independent of MCU response time. Use Value: Meets ISO 11452-4 EMC immunity requirements by avoiding software-based fault handling in high-noise motor drive environments. |
| Engine Control Unit (ECU) Diagnostics | Lighting Control Interface |
|
Use Scenario: Detecting simultaneous failure of two redundant crankshaft position sensors to trigger limp-home mode activation. IC Role / Device Role / Timing Role: Fail-safe logic element asserting diagnostic flag when both sensor outputs go low (NOR output high). Use Value: Provides deterministic, zero-latency fault detection that complies with UDS diagnostic session timing constraints (≤ 20 ms). |
Use Scenario: Enabling LED driver IC only when both dimming PWM and overtemperature shutdown signals are inactive. IC Role / Device Role / Timing Role: Safety interlock gate preventing LED turn-on during thermal fault conditions or invalid dimming command states. Use Value: Reduces system-level BOM count by replacing discrete transistor-based enable logic with a single qualified logic gate. |
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 |
|---|---|---|---|
| 74HCT1G02GV-Q100 | Same logic function and AEC-Q100 Grade 1 rating, but in SC-74A (SOT753) package - 3.1 mm × 1.7 mm vs. TSSOP5's 2.2 mm × 1.35 mm; 0.95 mm pitch vs. 0.65 mm. | Preferred for manual assembly or wave-soldered boards where larger pad spacing improves yield; less suitable for ultra-dense automotive PCBs. | Select when board assembly process favors wider pitch or thermal mass requirements exceed TSSOP5 limits. |
| SN74LVC1G02QDBVRQ1 | TI part with LVCMOS inputs (VIH = 1.7 V min at VCC = 3.3 V), 1.65–5.5 V supply range, and 3.7 ns typ tpd at VCC = 3.3 V - faster but not TTL-compatible. | Requires level-shifting for 5 V MCU interfaces; better suited for mixed-voltage domains (e.g., 3.3 V domain interfacing to 5 V sensors via translators). | Choose only if system operates below 3.6 V or requires sub-5 ns timing; avoid for direct 5 V TTL replacement. |
Compared with 74HCT1G02GW-Q100, the GV variant trades footprint density for assembly robustness, while the TI LVC variant offers higher speed and wider voltage range at the cost of TTL compatibility - making the GW version optimal for drop-in 5 V automotive logic upgrades requiring minimal layout change.

FAQ
Is 74HCT1G02GW-Q100 pin-compatible with non-automotive 74HCT1G02 variants?
Yes - it shares identical pinout (SOT353-1), logic function, and DC/AC electrical characteristics with industrial-grade 74HCT1G02GW. The Q100 suffix denotes AEC-Q100 qualification and extended temperature screening; no pin or functional changes are introduced.
Can this NOR gate drive a 50 Ω transmission line directly?
No - its output drive strength (±2.0 mA at VCC = 4.5 V) supports ≤ 30 pF capacitive loads under typical conditions. Driving 50 Ω lines requires external buffer or line driver ICs; use only for point-to-point logic-level signaling within same PCB domain.
What is the maximum allowable input voltage when VCC = 5.0 V?
Per absolute maximum ratings, input voltage may reach VCC + 0.5 V = 5.5 V, provided input clamping current remains ≤ ±20 mA. This requires external series resistor ≥ 270 Ω for 12 V inputs to limit IIK within spec.
Does this device support hot-swap or live-insertion?
No - it lacks power-on reset, bus-hold, or Ioff protection. Applying input signals before VCC stabilization may cause undefined output states or increased ICC. Power sequencing must ensure VCC is stable prior to valid input application.
