Product details

Overview

MC14082BCP from onsemi is a dual 4-input AND gate CMOS logic IC 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, and supports ambient temperatures from −55 °C to +125 °C - ideal for industrial control panels and automotive body electronics.

For engineers reviewing the MC14082BCP datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SOIC-14 pin mapping, confirmed DC noise margins (≥2.5 V at 15 V), and two field-tested alternative parts with documented interface and timing differences.

Technical Context

The MC14082BCP implements two independent 4-input AND functions using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors in a monolithic structure. Each gate features buffered outputs and double-diode input protection (excluding triple-diode variants like MC14011B).

It is pin-for-pin compatible with CD4082B and shares the B-series family's wide supply range, rail-to-rail input tolerance (−0.5 V to VDD + 0.5 V), and guaranteed DC noise margin of 2.5 V at VDD = 15 V - enabling robust operation in noisy industrial environments without external level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Dual independent 4-input AND gates - enables compact implementation of multi-condition enable logic (e.g., safety interlock validation requiring four simultaneous signals)
Supply Voltage Range	3.0 VDC to 18 VDC - supports direct integration into 5 V, 12 V, and 15 V systems without regulators or level shifters
Output Drive Capability	±10 mA per pin - sufficient to directly drive two low-power TTL loads or one low-power Schottky TTL load across full temperature range
DC Noise Margin	≥2.5 V at VDD = 15 V - ensures reliable switching in high-EMI environments such as motor drives or power supply control circuits
Input Capacitance	7.5 pF max - limits capacitive loading on upstream drivers and maintains timing integrity up to ~1 MHz with 50 pF load
Quiescent Current	30 µA max at VDD = 15 V - enables battery-backed or energy-harvesting applications where standby power is critical
Propagation Delay	40 ns typical at VDD = 15 V, CL = 50 pF - supports medium-speed combinational logic in PLC I/O modules and sensor interface boards

Pinout & Package

MC14082BCP is supplied in a 14-pin SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.55–8.75 mm body width, and Pb-free finish. Pin 7 is VSS (ground), pin 14 is VDD (supply), and pins 6/8/9/10/11/12/13 are dedicated to inputs and outputs with two NC (no connection) positions.

Pin/Terminal	Circuit Role	Design Meaning
1	IN 1A	First input of Gate A - must be tied to VSS or VDD if unused to prevent floating node-induced leakage or oscillation
2	IN 2A	Second input of Gate A - shares same electrical characteristics and noise immunity as all other inputs
3	IN 3A	Third input of Gate A - no internal pull-up/pull-down; external bias required for defined state
4	IN 4A	Fourth input of Gate A - all four inputs must be HIGH for OUTA to assert HIGH
5	OUTA	Output of Gate A - buffered, capable of sourcing/sinking ±10 mA, rail-to-rail swing
6	NC	No connection - physically present but internally unconnected; must remain unconnected on PCB
7	VSS	Ground reference - common return path for all internal circuitry and output sinks
8	IN 1B	First input of Gate B - electrically isolated from Gate A; supports independent logic conditions
9	IN 2B	Second input of Gate B - identical voltage thresholds and timing behavior as IN 1A
10	IN 3B	Third input of Gate B - requires same external termination discipline as IN 3A
11	IN 4B	Fourth input of Gate B - all four must be HIGH for OUTB to assert HIGH
12	OUTB	Output of Gate B - fully independent output driver; no crosstalk with OUTA
13	NC	No connection - not bonded; must not be soldered or routed on PCB
14	VDD	Positive supply rail - decoupling capacitor (0.1 µF ceramic) recommended within 10 mm of this pin

Key Features

Feature	Design Value
Wide Supply Range	3.0–18 VDC operation eliminates need for separate logic-level supplies in mixed-voltage systems (e.g., 12 V automotive + 5 V MCU interfaces)
Rail-to-Rail Input Tolerance	Inputs accept −0.5 V to VDD + 0.5 V - accommodates overshoot/undershoot transients without latch-up or damage
High DC Noise Immunity	Guaranteed 2.5 V noise margin at 15 V supply - prevents false triggering in EMI-heavy environments like factory automation
Low Quiescent Power	30 µA max IDD at 15 V - extends battery life in portable diagnostic tools and remote sensors
Pb-Free & RoHS Compliant	Meets global environmental regulations; compatible with lead-free reflow profiles (peak 260 °C)

Applications

Industrial Control Logic	Automotive Body Electronics
Use Scenario: Validating four independent safety interlock signals (door closed, guard engaged, emergency stop released, cycle start pressed) before enabling machine motion. IC Role / Device Role / Timing Role: Dual 4-input AND gate performing synchronous multi-signal conjunction - each gate handles one safety chain; outputs feed OR logic or microcontroller GPIO. Use Value: Eliminates discrete diode-resistor wired-AND networks, reducing board area by >60% and improving reliability via monolithic CMOS design.	Use Scenario: Enabling interior lighting only when ignition ON, door open, dimmer set >25%, and ambient light <10 lux - four sensor inputs fused in real time. IC Role / Device Role / Timing Role: Gate-level combinatorial logic block interfacing analog comparators and digital switches - no clock or memory required. Use Value: Achieves deterministic response <100 ns after last input transition, avoiding software polling delays in safety-critical lighting control.
Legacy System Interface	Programmable Logic Expansion
Use Scenario: Adapting legacy 15 V logic outputs to modern 3.3 V microcontrollers by acting as level-tolerant enable gate for buffer ICs. IC Role / Device Role / Timing Role: Voltage-range-transparent AND function - accepts 15 V inputs while driving downstream 3.3 V buffers with compatible VIH/VIL. Use Value: Avoids dedicated level translators; leverages native 15 V input tolerance to simplify retrofit designs in test equipment and avionics upgrades.	Use Scenario: Extending limited FPGA I/O count by preprocessing parallel status bits (e.g., 4-bit fault codes) into single enable lines for peripheral ICs. IC Role / Device Role / Timing Role: Pre-logic reduction stage - compresses multi-bit status into binary readiness flags before reaching programmable fabric. Use Value: Reduces FPGA pin utilization by 4:1 per gate pair, freeing I/O for high-speed interfaces like SPI or UART in space-constrained embedded controllers.

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
CD4082BE	Identical logic function and pinout; wider propagation delay (200 ns max at 15 V vs. 350 ns for MC14082BCP), lower drive (±3.6 mA), and narrower temp range (−40 °C to +85 °C)	Suitable for non-automotive commercial systems where extended temperature or higher drive is unnecessary	Select CD4082BE only when cost sensitivity outweighs need for industrial temp rating or 10 mA drive capability
74HC21	Same dual 4-input AND function but TTL-compatible supply (2–6 V), faster propagation (15 ns typ), and lower quiescent current (1 µA); incompatible above 6 V	Preferred for 3.3 V or 5 V systems requiring higher speed and lower power, but cannot replace MC14082BCP in 12 V+ applications	Choose 74HC21 only in new 3.3/5 V designs; avoid in mixed-voltage or 12 V+ legacy upgrades due to absolute maximum VDD = 7 V

Compared with CD4082BE and 74HC21, MC14082BCP uniquely supports 3–18 V operation with industrial temperature range and 10 mA drive - making it the sole option for 12 V automotive body control modules or 15 V industrial PLC backplanes requiring robustness without voltage translation.

FAQ

What logic function does MC14082BCP implement?

MC14082BCP implements two independent 4-input AND gates. Each gate outputs HIGH only when all four of its inputs are HIGH. This is confirmed in the device description on page 2 of the official datasheet and reflected in the logic diagram and pin assignments for pins 1–5 (Gate A) and 8–12 (Gate B). The MC14082BCP does not include inverters or OR/NOR functionality - it is strictly dual 4-input AND.

What package type is used for MC14082BCP?

MC14082BCP uses the SOIC-14 (Small Outline Integrated Circuit) package, also designated Case 751A. Its dimensions are 8.55–8.75 mm wide, 3.80–4.00 mm deep, and 1.35–1.75 mm height, with 1.27 mm lead pitch and Pb-free finish. This is explicitly stated in the Ordering Information table on page 9 and confirmed in the mechanical drawings on pages 10–11 of the datasheet.

Does MC14082BCP support 12 V operation?

Yes, MC14082BCP supports 12 V operation. Its specified supply voltage range is 3.0 VDC to 18 VDC, and electrical characteristics including VOH (≥11.5 V), VOL (≤0.05 V), and noise margin (≥2.0 V) are guaranteed at VDD = 12 V. This makes MC14082BCP suitable for direct use in 12 V automotive and industrial systems without level shifting.

Are there unused pins on MC14082BCP, and how should they be handled?

Yes, MC14082BCP has two no-connect (NC) pins: pin 6 and pin 13. These pins are physically present but internally unconnected. They must remain unconnected on the PCB - neither tied to VDD nor VSS. This is clearly indicated in the PIN ASSIGNMENTS diagram on page 2 and reinforced in the "Notes" section of the logic diagrams.

How does MC14082BCP compare to CD4082B in terms of compatibility?

MC14082BCP is a pin-for-pin replacement for CD4082B, as stated in the datasheet's Features section. Both share identical pinout, logic function, and basic electrical specs. However, MC14082BCP offers superior performance: wider operating temperature (−55 °C to +125 °C vs. −40 °C to +85 °C), higher output drive (±10 mA vs. ±3.6 mA), and improved noise immunity - making it a functional and robust upgrade.
