Product details
Overview
MC14012BDR2 from onsemi is a dual 4-input NAND gate CMOS logic IC built with complementary P- and N-channel enhancement-mode MOSFETs in a monolithic structure. It operates across 3.0–18.0 VDC supply, delivers ±10 mA output drive per pin, supports −55°C to +125°C ambient operation, and is used in low-power, high-noise-immunity digital control circuits such as industrial sequencers and battery-powered instrumentation.
For engineers reviewing the MC14012BDR2 datasheet, pinout, applications, or equivalent options, key selection considerations include its wide VDD range, buffered outputs, double diode input protection, SOIC-14 package compatibility with CD4000B-series designs, and AEC-Q100 qualification for automotive variants.
Technical Context
The MC14012BDR2 implements two independent 4-input NAND gates using CMOS technology, each with fully buffered outputs to ensure consistent fanout and noise rejection. Its input structure includes double diode protection against ESD and transient overvoltage, and all unused inputs must be tied to VDD or VSS to prevent floating states.
It exhibits rail-to-rail output swing (VOL ≤ 0.05 V at VDD = 5 V; VOH ≥ 4.95 V), guaranteed DC noise margins of 1.0 V (at 5 V), 2.0 V (at 10 V), and 2.5 V (at 15 V), and switching performance characterized up to 100 ns propagation delay (tPLH/tPHL) under CL = 50 pF at VDD = 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - enables direct interface with legacy 5 V, modern 3.3 V, and high-voltage industrial rails without level shifters |
| Output Drive Capability | ±10 mA per pin - sufficient to drive two low-power TTL loads or one low-power Schottky TTL load across full temperature range |
| Input Protection | Double diode clamping on all inputs - provides robust ESD immunity and transient suppression per IEC 61000-4-2 Level 2 |
| Operating Temperature | −55°C to +125°C - supports deployment in extended-temperature industrial, automotive, and aerospace environments |
| Quiescent Current | 0.25 µA typical at 5 V, 25°C - ensures ultra-low standby power for battery-backed systems |
| Propagation Delay | 50 ns max at VDD = 15 V, CL = 50 pF - suitable for medium-speed combinatorial logic in timing-critical control paths |
| DC Noise Margin | 2.5 V at VDD = 15 V - guarantees reliable logic state retention in electrically noisy factory-floor or motor-drive applications |
Pinout & Package
MC14012BDR2 is housed in a Pb-free SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.55–8.75 mm body width, and 3.80–4.00 mm body length. Pin 7 is VSS (ground), Pin 14 is VDD (supply), Pins 6 and 8 are no-connect (NC), and both gates share common power/ground rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | OUTA / OUTB | Buffered NAND output terminals - drive external loads directly; require no external pull-ups |
| 2, 3, 4, 5 | IN1A, IN2A, IN3A, IN4A | Inputs for Gate A - all four must be high to assert low on OUTA; floating inputs cause undefined output |
| 9, 10, 11, 12 | IN1B, IN2B, IN3B, IN4B | Inputs for Gate B - functionally identical to Gate A; electrically isolated but share VDD/VSS |
| 7 | VSS | Ground reference - must be connected to system ground plane with low-inductance path for noise immunity |
| 14 | VDD | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin |
| 6, 8 | NC | No internal connection - must remain unconnected; routing stubs prohibited to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18.0 VDC operation eliminates need for separate voltage regulators in mixed-rail systems |
| Input Diode Protection | Integrated double-diode clamps reduce external TVS requirements and simplify board-level ESD design |
| Buffered Outputs | On-die output buffers maintain consistent rise/fall times and fanout capability across voltage and temperature |
| Pb-Free & RoHS Compliant | Meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 3 moisture sensitivity |
| Pin-for-Pin CD4000B Replacement | Direct drop-in upgrade path for legacy CD4012B designs without PCB or firmware changes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4012BM96 | Same pinout and logic function, but narrower 3–15 V supply range and higher quiescent current (1 µA typical) | Lacks AEC-Q100 qualification and double-diode input protection; not rated for −55°C operation | Select for cost-sensitive non-automotive applications where extended temperature and enhanced ESD are not required |
| 74HC20PW,118 | Higher speed (20 ns tPD at 4.5 V), but limited to 2–6 V supply and lower noise margin (0.4 V at 4.5 V) | Not suitable for 12 V or 15 V industrial rails; requires level translation when interfacing with legacy CMOS or TTL | Choose for high-speed 3.3 V digital systems where propagation delay dominates over supply flexibility |
Compared with CD4012BM96 and 74HC20PW,118, the MC14012BDR2 uniquely combines ultra-wide supply range (3–18 V), extended temperature support (−55°C to +125°C), integrated input protection, and automotive qualification-making it the only option for ruggedized, mixed-voltage, safety-critical logic functions.

FAQ
What is the maximum operating supply voltage for MC14012BDR2?
The MC14012BDR2 supports a DC supply voltage range of −0.5 V to +18.0 V referenced to VSS, with absolute maximum rating of +18.0 V. Operation above 18.0 V risks permanent damage. For reliable long-term use, the recommended range remains 3.0 V to 18.0 V as specified in the Electrical Characteristics table. The MC14012BDR2 must never be operated outside these limits even momentarily.
Does MC14012BDR2 have built-in ESD protection on its inputs?
Yes, the MC14012BDR2 features double diode protection on all inputs, as explicitly stated in the Features section of the datasheet. This internal clamping structure guards against electrostatic discharge and transient overvoltage events, reducing or eliminating the need for external TVS diodes in many applications. The MC14012BDR2 is rated for ±10 mA DC or transient input/output current per pin, consistent with this protection scheme.
Can MC14012BDR2 replace CD4012B in existing designs?
Yes, the MC14012BDR2 is explicitly designated as a pin-for-pin replacement for corresponding CD4000 series B-suffix devices, including CD4012B. It shares identical SOIC-14 pinout, logic function, and electrical compatibility across the 3.0–18.0 V range. The MC14012BDR2 also adds enhancements like double diode input protection and improved noise margins, making it a direct, drop-in upgrade without layout or firmware changes.
What is the guaranteed DC noise margin of MC14012BDR2 at 15 V supply?
At VDD = 15.0 VDC, the MC14012BDR2 guarantees a minimum DC noise margin of 2.5 V for both logic "0" and "1" levels, as confirmed in the DC Noise Immunity section (Figure 14) and Electrical Characteristics table. This margin is derived from the difference between VIH(min) = 11.0 V and VIL(max) = 4.0 V, ensuring robust operation in electrically noisy environments such as motor drives or industrial power systems.
Is MC14012BDR2 suitable for automotive applications?
The MC14012BDR2 itself is not automotive-qualified, but its NLV14012BDR2 variant is AEC-Q100 qualified and PPAP capable. While the MC14012BDR2 shares the same SOIC-14 package, electrical specs, and pinout, only the NLV prefix version meets automotive reliability and traceability requirements. For production automotive use, specify NLV14012BDR2; the MC14012BDR2 remains appropriate for industrial and commercial applications demanding extended temperature and high noise immunity.
