Product details
Overview
MC14073BFELG from onsemi is a triple 3-input AND gate CMOS logic IC in SOEIAJ-14 (JEDEC MS-012) package, operating from 3.0 V to 18.0 V supply, delivering ±10 mA output drive per pin, with guaranteed DC noise margins of 2.5 V at 15 V supply and input capacitance of 5.0–7.5 pF. It serves as a low-power combinational logic building block in industrial control sequencers and battery-powered instrumentation.
For engineers reviewing the MC14073BFELG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SOEIAJ-14 pin mapping, confirmed 3-input AND gate behavior across −55 °C to +125 °C, and two field-tested alternative parts for design continuity.
Technical Context
The MC14073BFELG implements three independent 3-input AND functions using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Each gate features buffered outputs and double diode input protection (excluding triple-diode variants like MC14011B).
It belongs to the B-suffix series designed for high noise immunity and low static power dissipation, with quiescent current as low as 0.5 µA per package at 25 °C and full rail-to-rail output swing (VOL ≤ 0.05 V, VOH ≥ VDD − 0.05 V at VDD = 5–15 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input AND gate - three independent gates, each requiring all three inputs HIGH to assert HIGH output |
| Supply Voltage Range | 3.0 V to 18.0 V DC - supports wide-input industrial and automotive battery rails without regulation |
| Output Drive Capability | ±10 mA per pin - sufficient to directly drive two low-power TTL loads or one low-power Schottky TTL load |
| DC Noise Margin | 2.5 V at VDD = 15 V - ensures robust operation in electrically noisy environments such as motor controls |
| Input Capacitance | 5.0–7.5 pF - enables stable timing with minimal capacitive loading on preceding stages |
| Operating Temperature | −55 °C to +125 °C - qualified for extended industrial and under-hood automotive applications |
| Quiescent Current | 0.5 µA typical at 25 °C - enables multi-year battery life in always-on sensor interface circuits |
Pinout & Package
MC14073BFELG uses the SOEIAJ-14 (JEDEC MS-012) surface-mount package - 14-pin small-outline integrated circuit with 1.27 mm pitch, gull-wing leads, and Pb-free finish. Dimensions: 8.65 × 3.90 × 1.75 mm (L × W × H), compliant with IPC-7351B footprint standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Input A1, A2, A3 of Gate A | Three dedicated inputs for first AND gate; all must be HIGH for OUTA to go HIGH |
| 4 | Output A (OUTA) | Buffered AND result of Pins 1–3; drives downstream logic or LED indicators |
| 5, 6, 7 | Input B1, B2, B3 of Gate B | Three dedicated inputs for second AND gate; unused inputs must tie to VDD or VSS |
| 8 | VSS (Ground) | Common reference for all logic levels and internal substrate; must be low-impedance |
| 9, 10, 11 | Input C1, C2, C3 of Gate C | Three dedicated inputs for third AND gate; compatible with 3.3 V, 5 V, and 12 V logic families |
| 12 | Output C (OUTC) | Buffered AND result of Pins 9–11; shares same electrical specs as OUTA/OUTB |
| 13 | Output B (OUTB) | Buffered AND result of Pins 5–7; electrically isolated from other outputs |
| 14 | VDD (Supply) | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18.0 V operation eliminates need for level shifters when interfacing with mixed-voltage systems |
| High Noise Immunity | Guaranteed 2.5 V DC noise margin at 15 V supply prevents false triggering in EMI-heavy environments |
| Low Static Power | 0.5 µA typical IDD enables use in ultra-low-power wake-up logic and battery-backed state retention |
| Pb-Free & RoHS Compliant | SOEIAJ-14 package meets EU RoHS Directive 2011/65/EU and JESD204B lead-free soldering requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4073BM96 | Same logic function and pinout; wider propagation delay (200 ns max at 5 V vs. 150 ns for MC14073B); lower max supply (15 V) | Compatible in legacy 5 V-only systems but not rated for 18 V operation or −55 °C start-up | Select when cost sensitivity outweighs extended voltage/temp range needs |
| MC14073BDR2G | Identical electrical specs and logic; SOIC-14 package instead of SOEIAJ-14 - 1.27 mm vs. 1.27 mm pitch but different body width (3.90 mm vs. 3.90 mm) and lead form | Requires PCB land pattern revision due to different package outline and thermal pad absence | Select for automated assembly compatibility with standard SOIC pick-and-place feeders |
Compared with CD4073BM96 and MC14073BDR2G, MC14073BFELG offers the widest operating voltage (up to 18 V), highest temperature rating (125 °C), and JEDEC-standard SOEIAJ-14 footprint optimized for high-density routing in space-constrained industrial modules.

FAQ
What logic function does the MC14073BFELG implement?
The MC14073BFELG implements three independent 3-input AND gates. Each gate outputs HIGH only when all three of its inputs are HIGH. This is confirmed by the device description, logic diagram, and pin assignments in the official onsemi datasheet. The MC14073BFELG does not include inverters or OR/NOR functionality - it is strictly a triple 3-input AND device.
What is the maximum supply voltage rating for MC14073BFELG?
The absolute maximum DC supply voltage (VDD) for MC14073BFELG is +18.0 V, with a minimum of −0.5 V. The recommended operating range is 3.0 V to 18.0 V DC, as specified in the Maximum Ratings table. Exceeding 18.0 V risks permanent damage, and operation below 3.0 V may result in undefined logic states or increased propagation delay.
Does MC14073BFELG have built-in input protection?
Yes, MC14073BFELG includes double diode protection on all inputs, as stated in the Features section of the datasheet. This protects against transient overvoltage events up to ±3000 V (Human Body Model ESD). Unlike MC14011B or MC14081B, it does not feature triple diode protection - only the double-diode configuration applies to MC14073BFELG.
Is MC14073BFELG pin-compatible with CD4073B devices?
Yes, MC14073BFELG is explicitly documented as a pin-for-pin replacement for corresponding CD4000-series B-suffix devices, including CD4073B. The pin assignments, logic function, and electrical interface match exactly - making MC14073BFELG a direct drop-in upgrade with improved noise immunity and wider supply range.
What package type is used for MC14073BFELG?
MC14073BFELG uses the SOEIAJ-14 package (also known as JEDEC MS-012), a 14-pin small-outline package with gull-wing leads, 1.27 mm pitch, and Pb-free finish. Its mechanical dimensions (8.65 × 3.90 × 1.75 mm) and land pattern differ from SOIC-14 and TSSOP-14 - requiring dedicated PCB layout per the onsemi package outline drawing 98ASB42565B.
