Product details
Overview
MC14082BFEL from onsemi is a dual 4-input AND gate in the B-Series CMOS logic family, designed for low-power, high-noise-immunity digital control and signal conditioning. It operates across 3.0–18 VDC supply, delivers ±10 mA output drive per pin, supports –55°C to +125°C ambient operation, and features buffered outputs for reliable TTL-load interfacing in industrial timing and power management circuits.
For engineers reviewing the MC14082BFEL datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin assignments, confirmed voltage and drive specifications, real-world use cases in logic-level translation and enable gating, and two technically documented alternative parts with explicit interface and performance distinctions.
Technical Context
The MC14082BFEL implements two independent 4-input AND functions 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 that scale 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 uses double diode input protection (excluding triple-protection variants like MC14011B/MC14081B), requires unused inputs tied to VDD (AND logic), and is specified for driving two low-power TTL loads or one low-power Schottky TTL load across its full temperature range without derating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4082BM96 | Same logic function and pinout; lower max supply (15 V vs. 18 V); higher typical propagation delay (400 ns @ 15 V) | Not rated for 125°C operation; limited to commercial/industrial temp range (–40°C to +85°C) | Select when cost sensitivity outweighs extended temperature or voltage margin requirements |
| 74HC21PW,118 | CMOS HC-series; 2–6 V supply only; faster propagation (20 ns @ 4.5 V); no 125°C rating | Requires level-shifting above 6 V; unsuitable for direct 12 V or 15 V systems without external regulation | Choose for high-speed, low-voltage (3.3/5 V) applications where speed dominates supply flexibility |
Compared with CD4082BM96 and 74HC21PW,118, the MC14082BFEL uniquely supports 18 V operation and full –55°C to +125°C qualification, making it the only option for high-voltage industrial controls and under-hood automotive logic where extended voltage headroom and thermal resilience are mandatory.

FAQ
What is the logic function and gate count of the MC14082BFEL?
The MC14082BFEL integrates two independent 4-input AND gates in a single 14-pin EIAJ SOIC package. Each gate outputs HIGH only when all four of its inputs are HIGH. This dual-gate configuration enables compact implementation of multi-signal enable logic, safety interlocks, or parallel decision paths without requiring multiple discrete ICs. The MC14082BFEL is not a programmable device - its function is fixed and defined by its CMOS transistor-level schematic.
Does the MC14082BFEL support 12 V and 15 V supply operation?
Yes, the MC14082BFEL is fully specified for operation from 3.0 VDC to 18 VDC, including 12 V and 15 V nominal supplies. Electrical characteristics such as VOH (≥14.95 V at VDD = 15 V), VOL (≤0.05 V), VIH (≥11 V), and VIL (≤4.0 V) are guaranteed across this full range. Its ability to operate reliably at 15 V makes the MC14082BFEL suitable for industrial PLC I/O modules and automotive subsystems where higher supply rails improve noise margin and simplify power architecture.
What are the correct handling requirements for unused inputs on the MC14082BFEL?
All unused inputs on the MC14082BFEL must be tied to VDD (logic HIGH), as it implements AND logic. Leaving inputs floating risks metastability, increased supply current, or unintended output states due to noise coupling. The datasheet explicitly states: "All unused inputs of AND, NAND gates must be connected to VDD." Tying to VSS (ground) would force the associated gate output LOW regardless of other inputs, defeating intended functionality. Unused outputs (e.g., if only one gate is used) must remain open - no pull-up or pull-down is required or recommended.
Is the MC14082BFEL pin-compatible with CD4000-series devices?
Yes, the MC14082BFEL is a pin-for-pin replacement for the CD4082B, as confirmed in the official datasheet under "Pin–for–Pin Replacements for Corresponding CD4000 Series B Suffix Devices." Both share identical pin assignments (inputs A1–A4 on pins 1–4, OUTA on pin 5, VSS on pin 7, inputs B1–B4 on pins 8–11, OUTB on pin 12, NC on pin 13, VDD on pin 14). This compatibility allows drop-in upgrades in legacy designs, retaining existing PCB layouts while gaining improved noise immunity, wider supply range, and extended temperature capability inherent to the B-Series.
What is the maximum output current rating per pin for the MC14082BFEL?
The absolute maximum output current rating for the MC14082BFEL is ±10 mA per pin, as stated in the Maximum Ratings table. This limit applies to both sourcing (IOH) and sinking (IOL) conditions and must not be exceeded under any operating condition, including transient events. At VDD = 15 V, the typical sourced current is –4.2 mA (IOH) and sunk current is 8.8 mA (IOL) under specified test conditions. Exceeding ±10 mA risks permanent damage, so external buffering is required for loads demanding >10 mA, such as LEDs or relay coils.
