Product details
Overview
M74HC02RM13TR from STMicroelectronics is a high-speed CMOS quad 2-input NOR gate in TSSOP-14 package, operating from 2V to 6V supply, with typical propagation delay of 8ns at 6V, symmetrical output drive (±4mA), and high noise immunity (28% VCC). It serves as a logic-level combinatorial gate in digital control, interface buffering, and reset signal conditioning circuits.
For engineers reviewing the M74HC02RM13TR datasheet, M74HC02RM13TR pinout, M74HC02RM13TR application, or M74HC02RM13TR equivalent, key selection criteria include guaranteed 2–6V operation, ±4mA drive strength per output, 1µA max ICC at 25°C, TSSOP-14 thermal and space constraints, and compatibility with legacy 74-series logic timing and logic levels.
Technical Context
The M74HC02RM13TR implements four independent 2-input NOR gates using silicon gate C2MOS technology, with three-stage buffered outputs to ensure stable switching and high noise rejection. Each gate features identical input thresholds (VIH = 3.15V, VIL = 1.35V @ VCC = 4.5V) and rail-to-rail output swing under load.
Its AC performance is characterized with CL = 50 pF and input rise/fall times ≤400 ns (at VCC = 6V), delivering balanced tPLH/tPHL delays and matched transition times (tTLH/tTHL ≤19 ns typ. @ 4.5V). Input protection diodes and latch-up immunity support robust operation in mixed-signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2V to 6V - supports battery-powered and multi-rail digital systems without level shifters |
| tPD (Typ.) | 8ns @ VCC = 6V - enables use in sub-100MHz synchronous logic paths |
| IOL / IOH | ±4mA min. - drives standard TTL loads and multiple 74HC inputs directly |
| VNIH / VNIL | 28% VCC min. - rejects >1.2V noise on 4.5V rails, critical for noisy industrial PCBs |
| ICC (Max) | 1µA @ TA = 25°C - suitable for always-on low-power monitoring nodes |
| Operating Temp | −55°C to +125°C - qualified for automotive engine bay and industrial control enclosures |
| CIN | 5pF max. - minimizes capacitive loading on driving gates and clock distribution nets |
Pinout & Package
TSSOP-14 (Thin Shrink Small Outline Package), 4.9 × 6.4 mm body, 0.65 mm pitch, 1.2 mm max height, lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Active-low NOR outputs - sink/source up to 4mA, rail-to-rail swing |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | First input per gate - CMOS-compatible thresholds, protected against ESD |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Second input per gate - identical electrical specs to A inputs, fully interchangeable |
| 7 | GND | Digital ground reference - must be low-impedance connection to minimize ground bounce |
| 14 | VCC | Positive supply - bypassing with 100nF ceramic near pin is mandatory for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Quad 2-input NOR architecture | Four independent gates in one package - reduces board area vs discrete solutions and simplifies routing of complementary logic |
| Pin- and function-compatible with 74 series | Drop-in replacement for legacy 74LS02/74HC02 in existing designs - no layout or firmware changes required |
| High noise immunity (28% VCC) | Rejects common-mode transients ≥1.2V on 4.5V supplies - improves reliability in motor-drive or relay-switching environments |
| Symmetrical output impedance | Matched tPLH/tPHL and |IOH| = IOL - eliminates duty-cycle distortion in clocked or pulse-width modulated signals |
| Wide temperature range | −55°C to +125°C operation - validated for under-hood automotive and outdoor industrial deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC02DR | SOP-14 package; slightly higher ICC (2µA max); identical AC specs and pinout | Larger footprint; less suitable for space-constrained PCBs requiring fine-pitch assembly | Select when SOP handling infrastructure exists and thermal dissipation margin is >100mW |
| 74AHC02PW,118 | TSSOP-14; faster tPD = 5.1ns @ 5V; higher drive (±8mA); VCC = 2–5.5V only | Better speed/power trade-off but incompatible with 6V systems or extended temperature range | Select for high-speed data path gating where 6V operation is not required |
Compared with SN74HC02DR and 74AHC02PW,118, the M74HC02RM13TR uniquely supports full 2–6V operation and −55°C to +125°C range while maintaining 1µA quiescent current - making it optimal for wide-supply, thermally demanding embedded control.

FAQ
Is M74HC02RM13TR compatible with 5V TTL logic inputs?
Yes - its VIH (min. 3.15V @ VCC = 4.5V) and VIL (max. 1.35V) thresholds meet TTL input requirements. When powered at 5V, it reliably accepts standard TTL output levels (2.4V–5V for HIGH, 0V–0.8V for LOW) without external level shifting.
What is the maximum capacitive load this device can drive reliably?
The M74HC02RM13TR is characterized up to 50pF load (per AC specs), with guaranteed tPLH/tPHL and output swing. Driving >50pF may increase propagation delay and reduce edge rate; for >100pF loads, add a buffer stage or reduce trace length and stubs.
Does this part require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs must be tied to VCC or GND. Floating CMOS inputs cause increased ICC, potential oscillation, and ESD vulnerability. ST recommends connecting each unused input directly to VCC or GND; do not leave open or rely on PCB leakage.
Can M74HC02RM13TR operate at 2.0V supply with full functionality?
Yes - all DC and AC specifications (including VIH/VIL, VOH/VOL, tPD, and drive strength) are guaranteed down to 2.0V. At 2V, typical tPD is 27ns and output drive drops to ±2mA, but logic functionality remains fully compliant per datasheet limits.
