Product details
Overview
MC74VHC02DTR2 from onsemi is a quad 2-input NOR gate in TSSOP-14 package, operating from 2.0 V to 5.5 V with 3.6 ns typical propagation delay at 5.0 V, 15 pF load. It features CMOS-level input compatibility, 5.0 V full-swing outputs, and is AEC-Q100 qualified for automotive use.
For engineers reviewing the MC74VHC02DTR2 datasheet, pinout, applications, or equivalent options, key selection factors include its 2.0–5.5 V supply range, TTL-compatible output swing, −Q automotive qualification, low 2 µA max ICC, and noise immunity (VNIH/VNIL = 28% VCC).
Technical Context
The MC74VHC02DTR2 implements four independent NOR logic functions using silicon-gate CMOS technology, with three-stage internal circuitry including a buffer output stage for high noise immunity and stable switching. Its inputs tolerate up to 5.5 V, enabling safe interfacing between 3.3 V and 5.0 V systems.
It supports operation across −55°C to +125°C, features power-down input protection, and exhibits balanced tPLH/tPHL propagation delays. The device is not tri-state; all outputs are push-pull, with no output enable control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - provides four independent Boolean OR-NOT operations per package |
| VCC Range | 2.0 V to 5.5 V - enables single-supply operation in mixed-voltage digital systems (e.g., 3.3 V logic with 5 V I/O) |
| tPD (Typ) | 3.6 ns at VCC = 5.0 V, CL = 15 pF - ensures high-speed timing in clock distribution, address decoding, and control logic |
| VIH / VIL | VIH(min) = 1.5 V @ VCC = 2.0 V; VIL(max) = 0.5 V @ VCC = 2.0 V - defines valid CMOS input thresholds for reliable logic level recognition |
| IOH / IOL | ±4 mA output drive @ VCC = 3.0–4.5 V - sufficient to drive standard CMOS loads and small fanouts without external buffers |
| ICC (Max) | 2 µA at TA = 25°C - ultra-low quiescent current supports battery-powered and energy-sensitive applications |
| VNIH / VNIL | 28% VCC - quantifies noise margin; e.g., 1.4 V noise immunity at VCC = 5.0 V, critical for robust operation in noisy environments |
Pinout & Package
TSSOP-14 package (Case 948G), 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, Pb-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 (Input) | First input of NOR gate 1 - must be tied to defined logic level if unused to prevent floating node instability |
| 2 | B1 (Input) | Second input of NOR gate 1 - paired with Pin 1 to determine Y1 output state per NOR truth table |
| 3 | Y1 (Output) | Active-low NOR output of Gate 1 - sinks current when both A1 and B1 are high; open-drain behavior not supported |
| 4 | A2 (Input) | First input of NOR gate 2 - electrically isolated from other gates; shares no internal resources |
| 5 | B2 (Input) | Second input of NOR gate 2 - identical electrical characteristics to Pins 1 and 2 |
| 6 | Y2 (Output) | Active-low NOR output of Gate 2 - capable of driving 4 mA load while maintaining VOL ≤ 0.44 V @ VCC = 4.5 V |
| 7 | GND | Ground reference for all logic and power domains - requires low-impedance PCB connection to minimize ground bounce |
| 8 | Y3 (Output) | Active-low NOR output of Gate 3 - matches timing and drive specs of Y1/Y2; not multiplexed or shared |
| 9 | A3 (Input) | First input of NOR gate 3 - same input structure as Pin 1, tolerant to 5.5 V regardless of VCC |
| 10 | B3 (Input) | Second input of NOR gate 3 - supports hot-insertion-safe operation due to input clamp protection |
| 11 | Y4 (Output) | Active-low NOR output of Gate 4 - final gate output; layout symmetry aids signal integrity in dense routing |
| 12 | A4 (Input) | First input of NOR gate 4 - decoupled from other inputs; no internal cross-talk path |
| 13 | B4 (Input) | Second input of NOR gate 4 - full 5.5 V tolerance allows direct connection to 5 V buses even when VCC = 3.3 V |
| 14 | VCC | Positive supply rail - must be bypassed with 0.1 µF ceramic capacitor near the pin to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| High-speed operation | 3.6 ns typical propagation delay at 5.0 V enables use in 100+ MHz control paths and fast address decoding |
| Wide supply range | 2.0 V to 5.5 V operation allows deployment across legacy 5 V, modern 3.3 V, and low-power 2.5 V systems without level shifters |
| Input overvoltage tolerance | Inputs withstand up to 5.5 V independent of VCC - eliminates need for external clamping diodes in mixed-voltage interfaces |
| Automotive qualification | AEC-Q100 Grade 1 qualified (−40°C to +125°C) and PPAP-capable - meets requirements for engine control, body electronics, and ADAS subsystems |
| Low dynamic noise | VOLP ≤ 0.8 V (max) at CL = 50 pF - reduces ground bounce and crosstalk in high-density PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC02APWR | Lower VCC min (1.65 V), higher speed (tPD = 3.0 ns typ @ 3.3 V), but only rated to 125°C (not AEC-Q100) | Preferred for commercial/industrial 1.8 V–3.3 V systems; lacks automotive qualification and 5.5 V tolerance | Select when operating below 3.3 V and AEC-Q100 is not required; verify 5 V input tolerance via external clamping if interfacing to 5 V signals |
| 74VHC02M | SOIC-14 package (Case 751A), identical electrical specs, but non-automotive grade (no −Q suffix or PPAP) | Suitable for cost-sensitive industrial controls where TSSOP footprint and automotive qualification are unnecessary | Choose for legacy PCB designs using SOIC footprints or where extended temperature range beyond 125°C is not needed |
Compared with SN74LVC02APWR and 74VHC02M, the MC74VHC02DTR2 uniquely combines AEC-Q100 qualification, 5.5 V input tolerance, and TSSOP-14 space efficiency - making it the only option qualified for under-hood automotive logic and mixed-voltage industrial edge nodes requiring long-term reliability.

FAQ
What is the maximum operating temperature range for the MC74VHC02DTR2?
The MC74VHC02DTR2 is rated for operation from −55°C to +125°C, meeting AEC-Q100 Grade 1 requirements. This extended range is validated across the full supply voltage (2.0 V to 5.5 V) and ensures reliable performance in under-hood automotive environments and industrial enclosures without forced cooling.
Does the MC74VHC02DTR2 support 3.3 V logic interfacing with 5 V systems?
Yes, the MC74VHC02DTR2 supports 3.3 V logic interfacing with 5 V systems. Its inputs tolerate up to 5.5 V regardless of VCC, and its outputs deliver full 5.0 V CMOS-level swings when VCC = 5.0 V - enabling direct connection to 5 V buses without external level shifters.
Is the MC74VHC02DTR2 pin-compatible with the MC74VHCT02ADTR2G?
No, the MC74VHC02DTR2 is not pin-compatible with the MC74VHCT02ADTR2G. While both are TSSOP-14 quad NOR gates, the MC74VHCT02A has TTL-compatible inputs (VIH ≈ 2.0 V), whereas the MC74VHC02DTR2 has CMOS-compatible inputs (VIH = 0.7×VCC). Their logic thresholds differ, requiring circuit redesign if substituted.
What is the quiescent supply current specification for the MC74VHC02DTR2?
The MC74VHC02DTR2 has a maximum quiescent supply current (ICC) of 2 µA at TA = 25°C and VCC = 5.5 V. This ultra-low static current makes it suitable for always-on battery-backed circuits and low-power IoT edge nodes where standby consumption must be minimized.
How does the MC74VHC02DTR2 handle unused inputs?
Unused inputs on the MC74VHC02DTR2 must be tied to a valid logic level - either VCC or GND - to prevent floating nodes that cause excessive current draw, oscillation, or ESD susceptibility. Leaving inputs unconnected violates the recommended operating conditions and may compromise device reliability or EMC performance.
