Product details

Overview

MC14082BD from onsemi is a dual 4-input AND gate CMOS logic IC designed for low-power, high-noise-immunity digital signal combining in industrial control and instrumentation 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 MC14082BD datasheet, pinout, applications, or equivalent options, this device serves as a pin-compatible B-series replacement for CD4000-family dual 4-input AND gates-critical for legacy system upgrades, power-constrained sensor interfaces, and wide-supply-rail industrial logic design.

Technical Context

The MC14082BD implements complementary MOS (CMOS) P- and N-channel enhancement-mode transistors in a monolithic structure, enabling rail-to-rail output swing and ultra-low quiescent current (≤1.0 µA at 15 V). Its dual-gate architecture isolates input logic paths while sharing VDD (Pin 14) and VSS (Pin 7), supporting independent 4-input AND functions without internal crosstalk.

All inputs are diode-protected (double protection), and unused inputs must be tied to VDD or VSS to prevent floating states. The device meets AEC-Q100 requirements when ordered with NLV prefix and supports Pb-free SOIC-14 packaging compliant with RoHS Directive 2011/65/EU.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Dual independent 4-input AND gates - enables parallel Boolean conjunction of four signals per channel without external gating.
Supply Voltage Range	3.0 VDC to 18 VDC - supports direct interface with 5 V, 12 V, and 15 V industrial power rails 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 across full temperature range.
Input Voltage Thresholds	VIL ≤ 4.0 V, VIH ≥ 11 V at VDD = 15 V - provides ≥2.5 V DC noise margin, ensuring robust operation in electrically noisy environments.
Propagation Delay	Max 60 ns at VDD = 15 V, CL = 50 pF - guarantees timing predictability in synchronous logic trees up to ~10 MHz toggle rates.
Quiescent Current	≤1.0 µA at VDD = 15 V - enables battery-backed or energy-harvesting applications where standby power is critical.

Pinout & Package

MC14082BD is housed in a 14-pin SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.55–8.75 mm body width, and 3.80–4.00 mm body length. Pin 1 identifies the top-left corner; Pin 7 is VSS (ground); Pin 14 is VDD (supply).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4	IN 1A, IN 2A, IN 3A, IN 4A	First 4-input AND gate inputs - all must be HIGH to assert OUTA (Pin 5); floating inputs cause undefined output.
5	OUTA	Output of first 4-input AND gate - buffered, rail-to-rail CMOS swing, capable of sourcing/sinking ±10 mA.
6, 7	NC, VSS	Pin 6 is no-connect; Pin 7 is ground reference - mandatory connection point for all internal logic and output stages.
8, 9, 10, 11	IN 1B, IN 2B, IN 3B, IN 4B	Second 4-input AND gate inputs - functionally identical to Pins 1–4 but electrically isolated from Gate A.
12	OUTB	Output of second 4-input AND gate - independent timing and loading behavior from OUTA; shares VDD/VSS only.
13, 14	NC, VDD	Pin 13 is no-connect; Pin 14 is positive supply - must be decoupled with 0.1 µF ceramic capacitor near package.

Key Features

Feature	Design Value
Rail-to-rail output voltage swing	VOH ≥ 14.95 V and VOL ≤ 0.05 V at VDD = 15 V - eliminates need for external level translators in mixed-voltage systems.
Wide operating temperature range	−55°C to +125°C - qualified for under-hood automotive, industrial PLC, and aerospace subsystem use without derating.
ESD protection	Human Body Model >3000 V - reduces risk of field failure during handling and board assembly in non-EPA environments.
Pb-free and RoHS-compliant packaging	SOIC-14 with "G" suffix - meets EU Directive 2011/65/EU and supports lead-free reflow profiles (J-STD-020D).
Pin-for-pin compatibility	Direct replacement for CD4082B - enables drop-in upgrade of legacy designs without PCB revision or layout change.

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 pinout and logic function; higher max supply (20 V), but only rated to +85°C and lacks AEC-Q100 qualification.	Suitable for commercial-grade consumer electronics; not recommended for automotive or extended-temperature industrial use.	Select CD4082BM96 only if operating ambient stays ≤85°C and RoHS compliance is not required.
74HC21PW,118	Higher speed (tPD ≈ 13 ns @ 4.5 V), but narrower supply range (2–6 V) and lower noise margin (1.0 V @ 5 V).	Better for high-speed digital systems with regulated 5 V rails; unsuitable for 12/15 V industrial supplies or noisy factory floors.	Choose 74HC21PW,118 when timing-critical 5 V logic is needed; avoid where supply voltage varies or EMI is present.

Compared with CD4082BM96 and 74HC21PW,118, the MC14082BD uniquely balances wide supply range (3–18 V), extended temperature support (−55°C to +125°C), and automotive-grade reliability-making it the sole option for ruggedized, multi-rail, or legacy-compatible designs requiring long-term availability.

FAQ

What logic function does the MC14082BD implement?

The MC14082BD implements two independent 4-input AND gates in a single SOIC-14 package. Each gate outputs HIGH only when all four of its inputs are HIGH. This functionality is confirmed in the device description, logic diagram, and pin assignments on page 2 of the official onsemi datasheet. The MC14082BD does not include inverters, OR, NAND, or NOR functions - its sole purpose is dual 4-input Boolean conjunction.

What is the maximum supply voltage rating for the MC14082BD?

The absolute maximum DC supply voltage (VDD) for the MC14082BD is +18.0 V, with a minimum of −0.5 V relative to VSS. Operation within the recommended 3.0 V to 18.0 V range ensures guaranteed performance across −55°C to +125°C. Exceeding +18.0 V risks permanent damage, as stated in the Maximum Ratings table on page 1 of the onsemi datasheet. The MC14082BD maintains valid logic thresholds and output drive capability across this entire range.

Does the MC14082BD have built-in input protection diodes?

Yes, the MC14082BD includes double diode protection on all inputs, as explicitly stated in the Features section on page 1 of the onsemi datasheet. This protection guards against transient overvoltage events and ESD spikes. Unlike some other devices in the MC14001B series (e.g., MC14011B), the MC14082BD does not feature triple diode protection - its input protection is specifically defined as double diode, consistent with B-series standard implementation for AND/NAND gates.

Can the MC14082BD directly drive TTL loads?

Yes, the MC14082BD is explicitly rated to drive two low-power TTL loads or one low-power Schottky TTL load across its full rated temperature range (−55°C to +125°C), as documented in the Features section on page 1 of the onsemi datasheet. Its ±10 mA output current capability and rail-to-rail VOH/VOL ensure compatible voltage levels and sufficient sink/source strength without external buffers - a key advantage over earlier CD4000-series devices.

Is the MC14082BD pin-compatible with the CD4082B?

Yes, the MC14082BD is specified as a pin-for-pin replacement for corresponding CD4000-series B-suffix devices, including the CD4082B, as confirmed in the Features section on page 1 of the onsemi datasheet. Both share identical SOIC-14 pinout (VSS = Pin 7, VDD = Pin 14, dual 4-input AND mapping), enabling direct substitution in legacy designs without PCB modification - provided the wider temperature and voltage capabilities of the MC14082BD are leveraged appropriately.
