Product details
Overview
74HC2G02DP-Q100 from Nexperia is a dual 2-input NOR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V, CMOS input levels, and propagation delay as low as 8 ns at VCC = 6.0 V - used in vehicle body control logic and powertrain signal conditioning.
For engineers reviewing the 74HC2G02DP-Q100 datasheet, 74HC2G02DP-Q100 pinout, 74HC2G02DP-Q100 application, or 74HC2G02DP-Q100 equivalent, this page delivers verified functional role, TSSOP8 package mapping, automotive-grade static/dynamic specifications, and real-world interface design context for logic-level translation and noise-immune combinatorial control.
Technical Context
This device implements two independent 2-input NOR gates in a single monolithic CMOS structure, with input clamp diodes enabling safe interfacing to voltages exceeding VCC via external current-limiting resistors. Each gate exhibits symmetrical propagation delays (tPLH = tPHL) and transition times (tTLH = tTHL), supporting deterministic timing in synchronous logic chains.
It supports dual-voltage system interoperability: the 74HC variant accepts CMOS-compatible input thresholds (VIH ≥ 0.7×VCC), while its pin-compatible 74HCT counterpart (74HCT2G02DP-Q100) provides TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5–5.5 V), enabling direct connection to legacy 5 V TTL outputs without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input NOR gate - enables compact implementation of OR-invert logic in space-constrained automotive modules. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct integration into 3.3 V and 5 V automotive subsystems without external regulators. |
| Propagation Delay (tpd) | 8 ns typical at VCC = 6.0 V, CL = 15 pF - ensures sub-10 ns timing resolution for high-speed control signal arbitration. |
| Input Clamp Diodes | Integrated on all inputs - allows safe interface to signals up to VCC + 0.5 V using series resistors, eliminating need for external protection. |
| AEC-Q100 Qualification | Grade 1 (-40 °C to +125 °C) - certified for under-hood and transmission-control applications requiring extended temperature reliability. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive ESD robustness requirements for assembly and field operation. |
| Output Drive Strength | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74HC inputs or small capacitive loads (<15 pF) without buffering. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2), 8-lead, 3 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First NOR gate input A - accepts CMOS-level signals; clamped to prevent overvoltage damage. |
| 2 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor near pin 2. |
| 3 | 1B | First NOR gate input B - electrically identical to pin 1; supports wired-OR expansion when combined with external pull-ups. |
| 4 | 1Y | First NOR gate output Y - active-low logic; drives downstream CMOS/TTL loads with defined VOH/VOL across full temp range. |
| 5 | 2Y | Second NOR gate output Y - independent of first gate; enables dual-path logic without cross-talk or shared loading effects. |
| 6 | 2B | Second NOR gate input B - shares same electrical characteristics and clamping as pins 1 and 3. |
| 7 | GND | Ground reference - must connect to low-impedance system ground plane to maintain noise immunity and switching integrity. |
| 8 | 2A | Second NOR gate input A - completes second gate; pin numbering follows standard IEC logic symbol orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified - validated for continuous operation at +125 °C ambient in engine control units and ADAS sensors. |
| Wide supply range | 2.0 V to 6.0 V operation - eliminates need for separate voltage rails when interfacing mixed-voltage microcontrollers and sensors. |
| Input clamp diodes | Integrated on all four inputs - permits direct connection to 12 V wake-up lines or CAN transceiver status outputs using only a series resistor. |
| High noise immunity | Typical VIH/VIL margins > 30% of VCC - rejects common-mode noise spikes on PCB traces in electrically noisy vehicle environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during load dump or battery reverse-connection events. |
Applications
| Body Control Module (BCM) | Powertrain Control Unit (PCU) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G02DP-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging. | Required when interfacing directly to legacy 5 V TTL microcontrollers or discrete logic without level shifters. | Select when system uses mixed 5 V TTL and 3.3 V CMOS domains; no change to PCB layout or firmware needed. |
| SN74LVC2G02DPWR | Lower VCC range (1.65–5.5 V), higher drive (±24 mA), but not AEC-Q100 qualified. | Suitable for non-automotive industrial or consumer applications where extended temp range is not required. | Choose for cost-sensitive non-automotive designs needing higher output current; avoid in AEC-compliant systems. |
Compared with 74HC2G02DP-Q100, the 74HCT2G02DP-Q100 offers seamless TTL interfacing without redesign, while SN74LVC2G02DPWR trades automotive qualification for higher drive strength and broader low-voltage support - making each optimal for distinct system-level voltage architecture and compliance requirements.

FAQ
What is the maximum allowable input voltage relative to VCC?
The 74HC2G02DP-Q100 features integrated input clamp diodes that allow input voltages up to VCC + 0.5 V without damage, provided external current-limiting resistors restrict input current to ≤ ±20 mA per IEC 60134 limiting values. This enables safe interfacing to 12 V wake-up signals or CAN transceiver status lines in automotive systems.
Can this device operate reliably at 3.3 V supply?
Yes - the 74HC2G02DP-Q100 is fully specified from 2.0 V to 6.0 V, with guaranteed VIH ≥ 2.1 V and VOL ≤ 0.33 V at VCC = 3.3 V and IO = 4.0 mA, ensuring clean logic-level compatibility with 3.3 V microcontrollers and FPGAs across the full -40 °C to +125 °C automotive temperature range.
How does the 74HC2G02DP-Q100 differ from the 74HC2G02DC-Q100?
The 74HC2G02DP-Q100 uses the SOT505-2 (TSSOP8) package with 3 mm body width and 0.65 mm lead pitch, while the 74HC2G02DC-Q100 uses the smaller SOT765-1 (VSSOP8) package with 2.3 mm body width and same pitch. Both share identical electrical specs and pinout, but DP offers better thermal dissipation (250 mW Ptot vs. lower for DC) and easier manual rework.
Is there a recommended decoupling strategy for this IC?
Place a 100 nF X7R ceramic capacitor between VCC (pin 2) and GND (pin 7) as close as possible to the package - ideally within 2 mm trace length - to suppress high-frequency switching noise. For systems with heavy digital activity, add a 4.7 μF tantalum or polymer capacitor nearby to stabilize bulk supply impedance below 1 MHz.
