Product details
Overview
MC74HC02ADR2 from onsemi is a quad 2-input NOR gate in high-performance silicon-gate CMOS technology, pin-compatible with LS02 logic. It operates from 2.0 V to 6.0 V, delivers ±25 mA output drive per pin, and supports automotive-grade operation (AEC-Q100 qualified). Used in digital control logic, reset generation, and enable/disable circuitry for industrial microcontroller peripherals.
For engineers reviewing the MC74HC02ADR2 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, propagation delay (13 ns @ 6 V), input leakage (<±1.0 µA), and automotive qualification status - all confirmed from onsemi's official MC74HC02A/D Rev. 16 datasheet.
Technical Context
The MC74HC02ADR2 implements four independent 2-input NOR gates using standard CMOS logic architecture. Each gate follows the Boolean function Y = A + B (active-low OR), with inputs compatible with both CMOS and LSTTL outputs when pullup resistors are used.
It features rail-to-rail output swing, low input current (≤1.0 µA), and guaranteed operation across −55°C to +125°C. The device meets JEDEC Std. No. 7.0A and includes ESD protection >2000 V HBM, making it suitable for noise-prone industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate (Y = A + B); enables compact combinational logic synthesis without external inversion. |
| Supply Voltage Range | 2.0 V to 6.0 V; supports dual-supply systems and battery-powered designs down to 2 V. |
| Propagation Delay | 13 ns max @ VCC = 6.0 V; ensures timing predictability in synchronous control paths up to ~30 MHz. |
| Output Drive | ±25 mA per pin; directly drives 10 LSTTL loads or interfaces with NMOS/CMOS/TTL without buffers. |
| Input Leakage | ±1.0 µA max @ VCC = 6.0 V; minimizes standby current in always-on logic monitoring circuits. |
| Operating Temperature | −55°C to +125°C; validated for under-hood automotive and extended industrial environments. |
| ESD Rating | >2000 V HBM; reduces risk of field failure during handling and board assembly. |
Pinout & Package

|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Input (A1/B1/A2/B2/A3/B3/A4/B4) | Dedicated gate inputs; each pair forms one NOR gate; unused inputs must be tied to VCC or GND. |
| 3, 6, 10, 13 | Output (Y1/Y2/Y3/Y4) | Active-low NOR outputs; capable of sourcing/sinking ±25 mA; rail-to-rail swing. |
| 7 | GND | Ground reference for all logic and power domains; requires low-impedance PCB connection. |
| 14 | VCC | Positive supply input (2.0–6.0 V); decoupling capacitor (0.1 µF) recommended adjacent to pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC02DR | Same logic function and SOIC-14 package; TI version has slightly higher ICC (20 µA typ vs. 1.0 µA max) and no AEC-Q100 qualification. | Not certified for automotive use; suitable for commercial/industrial grade only. | Select SN74HC02DR for cost-sensitive non-automotive designs where AEC-Q100 is not required. |
| 74VHC02M | Higher speed (7.5 ns @ 5 V), lower CPD (16 pF), but narrower VCC range (2.0–5.5 V) and no −Q automotive variant. | Limited to 5.5 V systems; lacks PPAP capability and automotive change control. | Choose 74VHC02M when sub-10 ns propagation is critical and supply voltage stays ≤5.5 V. |
Compared with SN74HC02DR and 74VHC02M, MC74HC02ADR2 uniquely combines AEC-Q100 qualification, 6.0 V operation, and ultra-low input leakage - making it the only option among the three qualified for under-hood automotive logic and wide-input-voltage industrial controllers.
