Product details
Overview
MC14073BD from onsemi is a triple 3-input AND gate CMOS logic IC designed for low-power, high-noise-immunity digital control and signal conditioning in industrial and automotive systems. It operates across 3.0–18.0 VDC supply, delivers ±10 mA output drive per pin, supports −55 °C to +125 °C ambient, and features buffered outputs with double-diode input protection.
For engineers reviewing the MC14073BD datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, temperature-rated drive capability, noise margin data, and pin-for-pin alternatives within the B-series CMOS logic family.
Technical Context
The MC14073BD implements three independent 3-input AND functions using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors in a monolithic structure. Each gate has fully buffered outputs and shares common VDD (Pin 14) and VSS (Pin 7) rails.
Input thresholds are supply-dependent: at VDD = 5.0 V, VIH = 3.5 V min and VIL = 1.5 V max; at VDD = 15.0 V, VIH = 11.0 V min and VIL = 4.0 V max. Propagation delay ranges from 40 ns (typ, VDD = 15 V, CL = 50 pF) to 200 ns (max, VDD = 5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input AND gate - enables multi-condition enable logic with single-package integration of three independent decision paths. |
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - supports wide-input industrial power rails and battery-backed operation without level-shifting. |
| Output Drive Capability | ±10 mA per pin - sufficient to directly drive two low-power TTL loads or one low-power Schottky TTL load over full temperature range. |
| Input Protection | Double diode protection on all inputs - guards against transient overvoltage up to ±0.5 V beyond rail limits without external clamping. |
| Quiescent Current | 0.25 µA typical at 25 °C (VDD = 5 V) - enables ultra-low standby power in always-on monitoring circuits. |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive, motor control, and harsh-environment industrial use. |
| DC Noise Margin | ≥1.0 V at 5 V supply - ensures robust immunity to coupled noise in mixed-signal PCB layouts. |
Pinout & Package
MC14073BD is housed in a 14-lead SOIC (Small Outline Integrated Circuit) package, case 751A, with Pb-free finish (G suffix). Dimensions: 8.55–8.75 mm × 3.80–4.00 mm × 1.35–1.75 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Input A1, A2, A3 of Gate A | Three logic inputs for first AND gate; all must be HIGH for output A (Pin 4) to assert HIGH. |
| 4 | Output A | Buffered AND result of Pins 1–3; drives downstream logic or interface circuitry. |
| 5, 6, 8 | Input B1, B2, B3 of Gate B | Three logic inputs for second AND gate; unused inputs must be tied to VDD or VSS. |
| 9 | Output B | Buffered AND result of Pins 5, 6, 8; electrically isolated from other outputs. |
| 10, 11, 13 | Input C1, C2, C3 of Gate C | Three logic inputs for third AND gate; compatible with 3.3 V, 5 V, and 12 V logic families. |
| 12 | Output C | Buffered AND result of Pins 10, 11, 13; supports fan-out to multiple CMOS inputs. |
| 7 | VSS | Ground reference for all gates; must be connected to system ground with low-impedance path. |
| 14 | VDD | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required near Pin 14 for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply voltage range | 3.0–18.0 VDC operation eliminates need for separate voltage regulators in multi-rail systems. |
| High noise immunity | Guaranteed DC noise margin ≥1.0 V at 5 V supply reduces susceptibility to EMI in motor-drive or power-conversion environments. |
| Pin-for-pin compatibility | Direct replacement for CD4073B - simplifies legacy design upgrades without PCB revision. |
| Low quiescent current | Sub-microamp IDD at 25 °C enables use in battery-powered sensor nodes with multi-year runtime. |

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 | Same logic function and SOIC-14 pinout; wider propagation delay (250 ns max at 5 V) and narrower supply range (3–15 V). | Lacks AEC-Q100 qualification and automotive PPAP support; not rated for 125 °C operation. | Select CD4073BE only for cost-sensitive, non-automotive designs where extended temperature is unnecessary. |
| MC14073BDR2G | Identical electrical specs and logic function; differs only in packaging format (tape-and-reel vs. rail) and ordering code. | No functional or application difference - both are same die, same SOIC-14 package, same reliability data. | Choose MC14073BDR2G for automated SMT assembly; MC14073BD for manual prototyping or low-volume builds. |

FAQ
What logic function does the MC14073BD implement?
The MC14073BD implements three independent 3-input AND gates in a single SOIC-14 package. Each gate outputs HIGH only when all three of its inputs are HIGH. This configuration enables compact implementation of multi-condition logic in control systems without external combinational logic.
Is MC14073BD pin-compatible with CD4073B series devices?
Yes, MC14073BD is pin-for-pin compatible with CD4073B series devices, including CD4073BE. The pin assignments for inputs, outputs, VDD, and VSS match exactly, allowing direct substitution in existing SOIC-14 footprints without PCB modification.
What is the maximum operating temperature for MC14073BD?
The MC14073BD is rated for operation from −55 °C to +125 °C ambient temperature. This extended range is validated per onsemi's qualification testing and makes MC14073BD suitable for under-hood automotive applications and industrial environments with minimal thermal management.
Does MC14073BD require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on MC14073BD must be tied to either VDD or VSS to prevent floating states that cause excessive current draw and potential logic instability. For AND gates, unused inputs should be connected to VDD to avoid forcing output LOW.
Can MC14073BD drive TTL loads directly?
Yes, MC14073BD is specified to drive two low-power TTL loads or one low-power Schottky TTL load across its full rated temperature range. Its ±10 mA output drive capability and buffered outputs ensure reliable interfacing without additional buffer stages.
