Product details
Overview
74HCT2G02DP-Q100 from Nexperia is an automotive-grade dual 2-input NOR gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), operating from -40 °C to +125 °C, rated for 4.5–5.5 V supply, and packaged in TSSOP8 (SOT505-2). It enables robust level translation between legacy TTL systems and modern CMOS logic in engine control units and body electronics.
For engineers reviewing the 74HCT2G02DP-Q100 datasheet, 74HCT2G02DP-Q100 pinout, 74HCT2G02DP-Q100 application, or 74HCT2G02DP-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, 12 ns typical propagation delay at 4.5 V, 4 mA output drive capability, and input clamp diodes enabling safe interfacing to voltages exceeding VCC.
Technical Context
This device implements two independent NOR gates using silicon-gate CMOS technology, with inputs designed for direct compatibility with TTL output voltage levels. Its internal structure includes input clamp diodes that allow external current-limiting resistors when interfacing to signals above VCC.
The logic function follows standard Boolean NOR behavior: output is HIGH only when both inputs are LOW; otherwise, output is LOW. Propagation delays are characterized across temperature and supply voltage, with tpd = 12 ns (typ) at VCC = 4.5 V and CL = 15 pF, and transition times (tt) as low as 6 ns (typ) under same conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input NOR gate - provides two independent OR-NOT functions in one package for compact combinational logic design. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail and ensures stable operation across battery voltage fluctuations. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of TTL-level inputs (e.g., 74LS series) without level shifters. |
| Propagation Delay | 12 ns (typ) at VCC = 4.5 V, CL = 15 pF - supports timing-critical signal conditioning in powertrain and ADAS subsystems. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS inputs or small capacitive loads without buffering. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - enhances reliability during PCB handling and in-field operation in noisy vehicle electrical systems. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm pitch, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First NOR gate input A - accepts TTL/CMOS logic signals; includes clamp diode to VCC and GND. |
| 2 | 1B | First NOR gate input B - identical electrical characteristics to Pin 1; enables dual-input logic evaluation. |
| 3 | 1Y | First NOR gate output - active-low logic result (Y = NOT(A OR B)); drives downstream CMOS/TTL loads. |
| 4 | GND | Ground reference - must be connected to system 0 V plane; serves as return path for all internal currents. |
| 5 | 2Y | Second NOR gate output - electrically isolated from 1Y; allows independent use of second gate without crosstalk. |
| 6 | 2B | Second NOR gate input B - shares same input structure and threshold as Pins 1 and 2. |
| 7 | 2A | Second NOR gate input A - fully symmetrical to Pin 1; supports identical timing and voltage interface behavior. |
| 8 | VCC | Positive supply - powers both gates; requires local 100 nF decoupling capacitor near this pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, ensuring long-term reliability in engine control modules and transmission ECUs. |
| TTL-compatible input thresholds | Enables direct connection to legacy 74LS/74F logic without level-shifting circuitry, reducing BOM count and board space. |
| Input clamp diodes | Permits safe interface to signals up to VCC + 0.5 V using external current-limiting resistors, protecting against overvoltage transients. |
| Low dynamic power dissipation | CPD = 10 pF - minimizes switching power (PD = CPD × VCC² × fi × N), critical for thermally constrained automotive modules. |
| High noise immunity | Guaranteed VIH/VIL margins and hysteresis-free inputs ensure robust operation in high-EMI environments like power inverters and motor drivers. |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|

IC Role / Device Role / Timing Role: Implements combinatorial logic to inhibit conflicting outputs based on switch state priority encoding. Use Value: Prevents relay coil short-circuits and contact welding by enforcing mutually exclusive control paths at gate level. |
| Advanced Driver Assistance Systems (ADAS) | Infotainment Power Sequencing |
Use Scenario: Validating synchronized enable signals from radar and camera processors before activating shared power domain. IC Role / Device Role / Timing Role: Acts as a hardware AND-NOT gate (via NOR + inversion) to enforce strict co-activation requirement. Use Value: Provides sub-20 ns response time for safety-critical power gating, independent of software boot sequence delays. | Use Scenario: Generating delayed reset pulses for display controller and audio codec during cold start.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G02DC-Q100 | VSSOP8 package (2.3 mm width), identical electrical specs and AEC-Q100 qualification. | Higher board density required; tighter assembly tolerances due to smaller lead pitch and body size. | Select when PCB real estate is constrained and pick-and-place capability supports 0.5 mm pitch. |
| SN74LVC2G02QPWRQ1 | Wider VCC range (1.65–5.5 V), lower VIH (1.7 V min), but only AEC-Q100 Grade 2 (-40 °C to +105 °C). | Not suitable for under-hood applications exceeding +105 °C ambient; better for infotainment or cluster modules. | Choose for cost-sensitive designs where extended temperature is not required and 3.3 V logic integration is needed. |
Compared with 74HCT2G02DC-Q100, the DP variant offers easier rework and higher thermal mass in TSSOP8; versus SN74LVC2G02QPWRQ1, it delivers guaranteed +125 °C operation and stricter TTL threshold alignment at the expense of 3.3 V compatibility.

FAQ
What is the maximum allowable input voltage when using external current-limiting resistors?
The absolute maximum input voltage is VCC + 0.5 V, as defined in the limiting values table. Input clamp diodes conduct beyond this threshold, so external resistors must limit current to ≤ ±20 mA. For example, with VCC = 5.0 V and a 12 V external signal, a minimum 350 Ω resistor is required to stay within the ±20 mA clamp rating.
Can 74HCT2G02DP-Q100 drive a 50 pF load while maintaining specified propagation delay?
Yes - the datasheet specifies tpd = 29 ns (max) at VCC = 4.5 V and CL = 50 pF, measured per Fig. 5 test circuit. This value remains within the 35 ns design margin typically allocated for automotive signal integrity, confirming suitability for driving moderate-capacitance traces or multiple gate inputs.
Is there any functional difference between the DP and DC package variants besides physical dimensions?
No - both 74HCT2G02DP-Q100 (TSSOP8) and 74HCT2G02DC-Q100 (VSSOP8) share identical electrical specifications, thermal limits, AEC-Q100 qualification, and pinout mapping. The only differences are mechanical: body width (3.0 mm vs. 2.3 mm), lead pitch (0.65 mm vs. 0.5 mm), and thermal resistance (Rth(j-a) differs by ~15 K/W).
Does this device support hot-swap or live-insertion in powered systems?
No - the device lacks Ioff (power-off protection) or IOZ (three-state with power-down) features. Applying input signals while VCC is unpowered may forward-bias internal ESD diodes, causing unintended current paths. Always ensure VCC is stable before applying logic signals to avoid latch-up or parametric shift.
