Product details

Overview

MC14082BCPG from onsemi is a dual 4-input AND gate CMOS logic IC designed for low-power, high-noise-immunity digital signal processing in industrial control and instrumentation systems. It operates across a 3.0–18.0 VDC supply range, 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 MC14082BCPG datasheet, pinout, applications, or equivalent options, this device serves as a pin-compatible replacement for CD4082B in wide-supply-voltage logic interfacing, level translation, and combinational logic synthesis where input threshold stability and quiescent current below 1.0 µA at 5 V are critical selection criteria.

Technical Context

The MC14082BCPG implements two independent 4-input AND functions using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors in a monolithic structure. Its input thresholds scale with VDD - VIH = 3.5 V min at 5 V, 7.0 V at 10 V, and 11.0 V at 15 V - ensuring robust noise margins up to 2.5 V under full rail operation.

All inputs are diode-protected (double protection), unused inputs must be tied to VSS or VDD, and outputs are fully buffered to maintain consistent rise/fall times (tTLH/tTHL ≤ 40 ns typical at 15 V, CL = 50 pF). Propagation delay is specified as tPLH/tPHL ≤ 40 ns max at 15 V, supporting reliable timing in synchronous logic trees.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Dual independent 4-input AND gates - enables compact implementation of multi-signal enable/interlock logic without external gating.
Supply Voltage Range	3.0 VDC to 18.0 VDC - supports direct interface with 5 V, 12 V, and 15 V system rails without level shifters.
Input Thresholds (VIH/VIL)	VIH ≥ 3.5 V @ 5 V, ≥ 7.0 V @ 10 V, ≥ 11.0 V @ 15 V; VIL ≤ 1.5 V @ 5 V - ensures >2.0 V DC noise margin across operating range.
Output Drive Capability	±10 mA per pin - sufficient to directly drive two 74L series TTL loads or one 74LS load over full temperature range.
Quiescent Current (IDD)	≤ 1.0 µA @ 5 V, ≤ 30 µA @ 15 V - enables battery-backed or energy-harvesting applications requiring ultra-low standby power.
Propagation Delay	≤ 40 ns max @ VDD = 15 V, CL = 50 pF - supports reliable operation in clocked logic up to ~10 MHz toggle rate.
Operating Temperature	−55 °C to +125 °C - qualified for extended industrial, automotive under-hood, and aerospace subsystem use.

Pinout & Package

MC14082BCPG is housed in a Pb-free SOIC-14 (Case 751A) package with 1.27 mm pitch, 8.55–8.75 mm body width, and 1.35–1.75 mm height. Pin 7 is VSS (ground), pin 14 is VDD (supply), pins 1/2/3/4 and 10/11/12/13 are inputs, pins 5 and 9 are outputs, and pins 6 and 8 are no-connect (NC).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4	Inputs to Gate A	Four logic inputs for first AND function - all must be HIGH for output pin 5 to assert HIGH.
5	Output A	Active-HIGH AND result of pins 1–4 - buffered to drive capacitive loads up to 50 pF with controlled edge rates.
6, 8	No Connection (NC)	Internally unconnected - must remain floating; no external bias or routing required.
7	VSS	Ground reference for all internal circuitry - requires low-impedance connection to system ground plane.
9	Output B	Active-HIGH AND result of pins 10–13 - electrically isolated from Output A; supports independent logic paths.
10, 11, 12, 13	Inputs to Gate B	Four logic inputs for second AND function - identical electrical behavior to pins 1–4.
14	VDD	Positive supply rail - must be decoupled with ≥0.1 µF ceramic capacitor near pin for stable switching performance.

Key Features

Feature	Design Value
Wide Supply Range	3.0–18.0 VDC operation eliminates need for separate voltage regulators in mixed-rail systems.
High Noise Immunity	Guaranteed 2.5 V DC noise margin at 15 V supply - suppresses false triggering in EMI-prone industrial environments.
Low Quiescent Power	Sub-microamp IDD at 5 V enables multi-year battery life in always-on sensor monitoring nodes.
Pb-Free & RoHS Compliant	Meets global environmental directives - suitable for export-controlled and green-certified end equipment.
Automotive-Qualified Option	NLV14082B variants available with AEC-Q100 qualification and PPAP support for automotive body electronics.

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 (≤ 120 ns @ 15 V), higher quiescent current (≤ 5 µA @ 5 V), and narrower temp range (−40 °C to +85 °C).	Not qualified for extended industrial or automotive use; unsuitable for designs requiring >85 °C operation or sub-µA standby.	Select CD4082BM96 only for cost-sensitive consumer-grade designs with relaxed timing and temperature requirements.
74HC21PW,118	Higher speed (tPD ≤ 11 ns @ 4.5 V), but limited supply range (2.0–6.0 V); incompatible with 12 V/15 V systems without level shifting.	Requires external voltage translation for legacy 12 V control buses; not drop-in replaceable in existing MC14082BCPG layouts.	Choose 74HC21PW,118 only for new 3.3 V/5 V high-speed digital systems where rail compatibility is guaranteed.

Compared with CD4082BM96 and 74HC21PW,118, MC14082BCPG uniquely supports 3–18 V operation with −55 °C to +125 °C rating and sub-µA quiescent current - making it the sole option for ruggedized, wide-voltage, ultra-low-power AND logic in harsh environments.

FAQ

What logic function does the MC14082BCPG implement?

The MC14082BCPG implements two independent 4-input AND gates. Each gate outputs HIGH only when all four of its inputs are HIGH. This configuration enables hardware-level multi-condition validation without software intervention, and is explicitly confirmed in the device description and logic diagram sections of the onsemi datasheet.

What is the supply voltage range supported by MC14082BCPG?

The MC14082BCPG operates across a 3.0 VDC to 18.0 VDC supply range, verified in the Maximum Ratings table and Electrical Characteristics section. This allows direct integration into 5 V, 12 V, and 15 V systems without external regulation, and is a defining feature distinguishing it from narrower-range logic families like 74HC.

Does MC14082BCPG have any no-connect (NC) pins, and how should they be handled?

Yes, MC14082BCPG has two no-connect pins: pin 6 and pin 8. These terminals are internally unconnected and must remain unattached - neither grounded nor tied to VDD. The datasheet explicitly marks them as "NC" in the PIN ASSIGNMENTS diagram and confirms no routing or biasing is required.

What is the maximum operating temperature for MC14082BCPG?

The MC14082BCPG is rated for ambient temperatures from −55 °C to +125 °C, as stated in the Maximum Ratings table. This extended range is validated across all electrical parameters and makes the device suitable for under-hood automotive, industrial control cabinets, and aerospace applications where thermal stress is severe.

Is MC14082BCPG pin-compatible with CD4082B-series devices?

Yes, MC14082BCPG is explicitly documented as a pin-for-pin replacement for corresponding CD4000 series B-suffix devices, including CD4082B. The datasheet states this in the Features section and confirms identical pin assignments for both dual 4-input AND gate functions, enabling direct substitution in legacy designs.
