Product details
Overview
MC14082BDR2 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 sensor interface and power management sequencing.
For engineers reviewing the MC14082BDR2 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, confirmed switching timing (tPLH/tPHL ≤ 200 ns at VDD = 5 V), real-world noise margin data (≥1.0 V at 5 V), and two validated alternative parts with documented technical differences.
Technical Context
The MC14082BDR2 implements two independent 4-input AND gates 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-protected variants like MC14011B).
It is pin-for-pin compatible with CD4082B and shares the MC14001B series' wide supply range, rail-to-rail input tolerance (−0.5 V to VDD + 0.5 V), and guaranteed DC noise margins - 1.0 V at 5 V, 2.0 V at 10 V, and 2.5 V at 15 V - enabling robust operation in noisy environments without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 4-input AND gate - two independent combinatorial logic blocks, each requiring all four inputs HIGH to assert HIGH output. |
| Supply Voltage Range | 3.0 VDC to 18 VDC - supports single-supply operation across battery, industrial, and automotive subsystems without voltage regulation. |
| 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. |
| Propagation Delay | ≤200 ns at VDD = 5 V, CL = 50 pF - enables reliable timing in sub-5 MHz synchronous control and enable gating applications. |
| Input Voltage Thresholds | VIL ≤ 1.5 V, VIH ≥ 3.5 V at VDD = 5 V - ensures clean logic discrimination with >1.0 V DC noise margin under nominal supply. |
| Quiescent Current | ≤0.25 µA per package at 25 °C - enables ultra-low standby power in battery-backed or energy-harvesting systems. |
| Operating Temperature | −55 °C to +125 °C - qualified for extended industrial, automotive under-hood, and aerospace environmental stress profiles. |
Pinout & Package
MC14082BDR2 is housed in a Pb-free SOIC-14 (Case 751A) surface-mount package measuring 8.75 mm × 4.00 mm × 1.75 mm, with 1.27 mm pitch and gull-wing leads. Pin 1 is marked by a notch or beveled 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 | Four inputs of first AND gate - all must be HIGH for OUTA (pin 5) to go HIGH. |
| 5 | OUTA | Output of first 4-input AND gate - active-HIGH, buffered, capable of sourcing/sinking ±10 mA. |
| 6, 7 | NC, VSS | Pin 6 is no connection; pin 7 is ground reference - unused inputs must be tied to VSS or VDD. |
| 8, 9, 10, 11 | IN 1B, IN 2B, IN 3B, IN 4B | Four inputs of second AND gate - all must be HIGH for OUTB (pin 13) to go HIGH. |
| 12 | NC | No connection - not internally bonded; must remain unconnected in PCB layout. |
| 13 | OUTB | Output of second 4-input AND gate - electrically identical to OUTA, fully independent. |
| 14 | VDD | Positive supply rail - accepts 3.0–18 VDC; requires local 0.1 µF ceramic decoupling near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18 VDC operation eliminates need for multiple voltage rails in mixed-signal systems. |
| Rail-to-Rail Input Tolerance | Inputs tolerate −0.5 V to VDD + 0.5 V - simplifies interfacing with legacy TTL, CMOS, or analog threshold signals. |
| High Noise Immunity | Guaranteed 1.0 V DC noise margin at 5 V supply - reduces false triggering in EMI-prone motor control or power conversion circuits. |
| Low Quiescent Power | ≤0.25 µA typical IDD at 25 °C - enables use in always-on monitoring nodes without compromising battery life. |
| Pb-Free & RoHS Compliant | Meets EU RoHS Directive 2011/65/EU and AEC-Q100 for automotive-grade reliability (NLV prefix variants available). |
Applications
| Industrial Control Logic | Power Sequencing Supervisor |

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; wider propagation delay (≤250 ns at 5 V), higher quiescent current (≤1 µA), and narrower temp range (−40 °C to +85 °C). | Not rated for extended industrial or automotive environments; less suitable for high-reliability or wide-temperature deployments. | Select CD4082BM96 only for cost-sensitive, commercial-grade designs where extended temperature and ultra-low IDD are non-critical. |
| 74HC21PW,118 | Higher speed (tPD ≤ 17 ns at 4.5 V), but narrow supply range (2–6 V); incompatible with 12 V or 15 V systems without level translation. | Requires external voltage translation for >6 V operation; unsuitable for direct integration into multi-rail industrial power domains. | Choose 74HC21PW,118 when operating strictly at 3.3 V or 5 V with need for sub-20 ns timing - not for wide-supply or high-temp applications. |
Compared with CD4082BM96 and 74HC21PW,118, the MC14082BDR2 uniquely balances wide supply voltage (3–18 V), extended temperature support (−55 °C to +125 °C), and ultra-low quiescent current (<0.3 µA), making it the only option among the three viable for unregulated battery-powered or harsh-environment control logic.

FAQ
What logic function does the MC14082BDR2 implement?
The MC14082BDR2 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 section of the onsemi datasheet (page 2) and reflected in the pin assignments (pins 1–4 and 8–11 as inputs; pins 5 and 13 as outputs). The MC14082BDR2 does not include inverters or other combinational functions - it is strictly a dual 4-input AND device.
What package type and dimensions does the MC14082BDR2 use?
The MC14082BDR2 uses a Pb-free SOIC-14 package (Case 751A), with body dimensions of 8.75 mm × 4.00 mm × 1.75 mm and 1.27 mm lead pitch. This is explicitly stated in the ordering information (page 9) and mechanical drawings (pages 10–11). Pin 1 is identified by a notch or beveled corner; pins 6 and 12 are no-connect (NC) and must remain unconnected on the PCB.
Does the MC14082BDR2 support 12 V or 15 V operation?
Yes, the MC14082BDR2 supports supply voltages from 3.0 VDC to 18 VDC, including 12 V and 15 V operation. Electrical characteristics tables (page 3) list performance data at VDD = 5 V, 10 V, and 15 V - confirming guaranteed VOL ≤ 0.05 V and VOH ≥ 14.95 V at 15 V, with output drive current up to ±8.8 mA. This makes the MC14082BDR2 suitable for direct use in unregulated industrial power domains.
What is the maximum operating temperature for the MC14082BDR2?
The MC14082BDR2 is rated for an ambient temperature range of −55 °C to +125 °C, as specified in the Maximum Ratings table (page 1). This extended range is enabled by its B-suffix CMOS construction and is validated across all electrical parameters in the datasheet's characterization tables. It exceeds standard commercial-grade logic and meets requirements for under-hood automotive and industrial control cabinet applications.
Are unused inputs on the MC14082BDR2 required to be terminated?
Yes, all unused inputs on the MC14082BDR2 must be tied to a valid logic level - either VDD or VSS - as explicitly instructed in the datasheet (page 2, "Device Description" note and page 4, Figure 1 footnote). Leaving inputs floating can cause excessive supply current, oscillation, or unpredictable output states due to the high-impedance CMOS inputs. Unused outputs may be left open.
