Product details
Overview
MC14073BDG from onsemi is a triple 3-input AND gate CMOS logic IC designed for low-power, high-noise-immunity digital control functions in industrial and automotive systems. It operates across 3.0–18 VDC supply, delivers ±10 mA output drive per pin, and features buffered outputs capable of driving two low-power TTL loads over −55 °C to +125 °C.
For engineers reviewing the MC14073BDG datasheet, pinout, applications, or equivalent options, this device serves as a direct pin-for-pin replacement for CD4073B with extended voltage range, enhanced ESD robustness (>3 kV HBM), and Pb-free SOIC-14 packaging compliant with AEC-Q100 requirements.
Technical Context
The MC14073BDG implements three independent 3-input AND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors in a monolithic structure. Each gate exhibits rail-to-rail output swing, input thresholds scaling with VDD (VIH = 3.5 V at 5 V, 11 V at 15 V), and guaranteed DC noise margins of 1.0 V (5 V), 2.0 V (10 V), and 2.5 V (15 V).
It supports dynamic operation up to 3 MHz typical (CL = 50 pF, VDD = 15 V), with propagation delays ranging from 40 ns (15 V) to 200 ns (5 V), and quiescent current as low as 0.5 µA per package at 25 °C - enabling use in battery-backed and thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input AND gate - enables compact implementation of multi-condition enable logic without external gating. |
| Supply Voltage Range | 3.0 V to 18 V DC - supports wide-input industrial rails, battery systems, and legacy 12 V/15 V designs without level-shifting. |
| Output Drive Capability | ±10 mA per pin - sufficient to directly interface with TTL, Schottky TTL, and microcontroller GPIOs across full temperature range. |
| Input Thresholds (VIH/VIL) | VIL ≤ 4.0 V, VIH ≥ 11 V at VDD = 15 V - provides >2.5 V DC noise margin, critical for noisy motor-control or power-conversion environments. |
| Propagation Delay | 40–200 ns (VDD = 15–5 V, CL = 50 pF) - ensures deterministic timing in synchronous state machines and clocked combinatorial logic. |
| Quiescent Current | 0.5 µA typical at 25 °C - enables ultra-low standby power in always-on monitoring circuits and energy-harvesting nodes. |
| ESD Rating | >3000 V HBM - exceeds IEC 61000-4-2 Level 2, reducing need for external protection in panel-mounted or field-serviceable equipment. |
Pinout & Package
MC14073BDG is housed in a Pb-free SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.55–8.75 mm body width, and 1.35–1.75 mm height - compatible with standard surface-mount reflow profiles and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Input A1, A2, A3 of Gate A | Three independent logic inputs feeding first AND gate; all must be HIGH for output pin 4 to assert HIGH. |
| 4 | Output A | Active-HIGH AND result of pins 1–3; rail-to-rail CMOS swing, buffered to maintain drive strength under capacitive load. |
| 5, 6, 8 | Input B1, B2, B3 of Gate B | Inputs for second AND gate; pin 8 is physically adjacent to VDD (pin 14) to minimize switching noise coupling. |
| 9 | Output B | Active-HIGH AND result of pins 5, 6, 8; electrically isolated from Gate A/B outputs to prevent crosstalk in mixed-signal PCB layouts. |
| 10, 11, 12 | Input C1, C2, C3 of Gate C | Inputs for third AND gate; unused inputs must be tied to VDD (not floating) to prevent shoot-through current and metastability. |
| 13 | Output C | Active-HIGH AND result of pins 10–12; shares common VSS (pin 7) and VDD (pin 14) with other gates - requires local 100 nF decoupling. |
| 7 | VSS | Ground reference for all gates; must be connected to system ground plane with low-inductance path to suppress ground bounce. |
| 14 | VDD | Positive supply input; accepts 3–18 V DC; internal ESD protection diodes clamp transients to VDD/VSS rails. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range (3–18 V) | Eliminates need for dedicated logic regulators in multi-rail systems - simplifies power architecture and reduces BOM count. |
| Triple Independent Gates | Reduces footprint vs. three discrete dual-input ANDs; enables compact implementation of 3-input safety interlocks or sensor fusion logic. |
| High Noise Immunity | Guaranteed 2.5 V DC noise margin at 15 V supply - prevents false triggering in proximity to AC motors, solenoids, or switching power supplies. |
| Pb-Free SOIC-14 Packaging | RoHS-compliant and AEC-Q100 qualified (via NLV prefix variants) - suitable for automotive infotainment, body control modules, and industrial PLCs. |
| Buffered Outputs | Ensures consistent rise/fall times and load-driving capability across temperature - critical for reliable timing in clock distribution or reset generation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4073BE | Narrower supply range (3–15 V); lower ESD rating (2 kV HBM); no AEC-Q100 qualification. | Suitable for commercial-grade consumer electronics but not automotive or harsh industrial environments. | Select CD4073BE only for cost-sensitive, non-automotive designs where 15 V max supply suffices. |
| 74HC11D,653 | Higher speed (tPD = 10 ns @ 5 V), but limited to 2–6 V supply; TTL-compatible inputs; no 125 °C rating. | Better for high-frequency digital systems (e.g., FPGA glue logic), but incompatible with 12 V/15 V rails or extended temperature operation. | Choose 74HC11D only when operating below 6 V and requiring sub-15 ns propagation delay in ambient-temperature applications. |
Compared with CD4073BE and 74HC11D, MC14073BDG uniquely supports 18 V operation, −55 °C to +125 °C range, and >3 kV HBM - making it the only option for high-voltage industrial controls and automotive under-hood applications requiring long-term reliability without derating.

FAQ
What is the maximum supply voltage rating for MC14073BDG?
The MC14073BDG has an absolute maximum DC supply voltage (VDD) rating of +18.0 V, with operational specification confirmed from 3.0 V to 18.0 V. Exceeding 18.0 V risks permanent damage per the Absolute Maximum Ratings table. The device maintains full functionality - including output drive, noise margin, and propagation delay - across this entire range.
Does MC14073BDG support automotive qualification standards?
MC14073BDG itself is not AEC-Q100 qualified; however, its automotive-grade variant NLV14073BDG is explicitly listed in the datasheet as AEC-Q100 qualified and PPAP capable. For automotive applications requiring formal qualification, NLV14073BDG must be specified - MC14073BDG is intended for industrial and commercial use.
How should unused inputs be handled on MC14073BDG?
All unused inputs on MC14073BDG must be tied to a defined logic level - specifically to VDD (for AND/NAND gates) - to prevent floating nodes that cause excessive supply current, oscillation, or latch-up. Leaving inputs unconnected violates the Absolute Maximum Ratings and may degrade long-term reliability or cause functional failure.
What is the output drive capability of MC14073BDG at 12 V supply?
At VDD = 12 V, MC14073BDG delivers a minimum sink current (IOL) of 3.4 mA and source current (IOH) of −1.3 mA per output pin, as specified in the Electrical Characteristics table. This meets the requirement to drive two low-power TTL loads across the full −55 °C to +125 °C operating range without external buffering.
Is MC14073BDG pin-compatible with CD4073B series devices?
Yes - MC14073BDG is explicitly documented as a pin-for-pin replacement for CD4073B series devices. Pin assignments, function mapping, and package outline (SOIC-14) match identically. However, MC14073BDG extends the supply range to 18 V and improves ESD robustness, offering backward compatibility with performance enhancements.
