Product details

Overview

MC14082BDG from onsemi is a dual 4-input AND gate CMOS logic IC in SOIC-14 package, operating from 3.0 V to 18.0 V supply, delivering ±10 mA output drive per pin, with guaranteed DC noise margins of 2.5 V at 15 V supply, and used in industrial control logic decoding and power sequencing circuits.

For engineers reviewing the MC14082BDG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin assignments, confirmed supply and switching specifications, and real-world use context for B-series CMOS logic selection.

Technical Context

The MC14082BDG implements two independent 4-input AND functions using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. It features buffered outputs and double diode input protection (excluding triple-protection variants like MC14011B).

It belongs to the B-suffix series designed for low-power dissipation and high noise immunity, with pin-for-pin compatibility to CD4000-series equivalents and full operation across −55 °C to +125 °C ambient temperature range.

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 18.0 Vdc - supports wide-range industrial and legacy 5 V/12 V/15 V systems 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 over full temperature range.
DC Noise Margin	2.5 V at VDD = 15 V - ensures robust immunity against voltage transients and coupling noise in noisy environments.
Propagation Delay	40 ns max at VDD = 15 V, CL = 50 pF - enables reliable timing in medium-speed digital control and address decoding.
Quiescent Current	1.5 µA max at 15 V, 125 °C - ultra-low static power ideal for battery-backed or always-on logic monitoring circuits.
Input Capacitance	7.5 pF max - minimizes capacitive loading on upstream drivers and preserves signal integrity at higher frequencies.

Pinout & Package

MC14082BDG is housed in a Pb-free SOIC-14 (Case 751A) package, 8.55–8.75 mm wide, 3.80–4.00 mm body width, 1.35–1.75 mm height, with 1.27 mm pitch and gull-wing leads.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4	IN 1A, IN 2A, IN 3A, IN 4A	Four inputs to first AND gate - all must be HIGH for OUTA to go HIGH; unused inputs must be tied to VDD or VSS.
5	OUTA	Output of first 4-input AND gate - buffered, capable of sourcing/sinking ±10 mA.
6, 7	NC, VSS	No connection (pin 6); ground reference (pin 7) - VSS must be solidly decoupled to minimize ground bounce.
8, 9, 10, 11	IN 1B, IN 2B, IN 3B, IN 4B	Four inputs to second AND gate - electrically isolated from first gate; same biasing rules apply.
12	OUTB	Output of second 4-input AND gate - independent timing and loading behavior from OUTA.
13, 14	NC, VDD	No connection (pin 13); positive supply rail (pin 14) - requires local 0.1 µF ceramic decoupling capacitor.

Key Features

Feature	Design Value
Wide Supply Range	3.0–18.0 V operation enables drop-in replacement across legacy 5 V, 12 V, and 15 V logic systems without redesign.
High Noise Immunity	Guaranteed 2.5 V DC noise margin at 15 V supply ensures reliable operation in electrically noisy industrial PLC and motor-control environments.
Low Quiescent Power	Max 1.5 µA at 125 °C allows use in always-on supervisory logic without thermal or battery-life penalty.
Pb-Free & RoHS Compliant	SOIC-14 package marked with "G" suffix meets global environmental compliance requirements for industrial and automotive applications.
Temperature Robustness	Rated for −55 °C to +125 °C ambient enables deployment in under-hood automotive modules and outdoor telecom equipment.

Applications

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, but wider propagation delay (150 ns max at 5 V), lower drive (±3.6 mA), and narrower temp range (−40 °C to +85 °C).	Suitable only for low-speed, commercial-grade designs; not rated for extended temperature or high-noise industrial use.	Select when cost is primary constraint and performance specs are relaxed; verify layout decoupling for marginal noise immunity.
74HC21PW,118	Higher speed (20 ns typ at 4.5 V), but narrower supply range (2–6 V), no 15 V operation, and non-extended temperature rating (−40 °C to +125 °C).	Applicable in modern 3.3 V/5 V embedded systems but incompatible with legacy 12 V/15 V logic families.	Prefer for new 5 V designs needing faster timing; avoid in multi-rail or wide-VDD systems where MC14082BDG's flexibility is essential.

Compared with CD4082BM96 and 74HC21PW,118, the MC14082BDG uniquely supports 3–18 V operation, guarantees 2.5 V noise margin at 15 V, and maintains full functionality across −55 °C to +125 °C - making it the only choice for ruggedized, multi-voltage industrial logic interfacing.

FAQ

What logic function does the MC14082BDG implement?

The MC14082BDG implements two independent 4-input AND gates. Each gate outputs HIGH only when all four of its inputs are HIGH. This is confirmed by the device description on page 2 of the datasheet and the logic diagram on page 2 showing two separate 4-input AND structures. The MC14082BDG does not include inverters or other logic types - it is strictly dual 4-input AND.

What is the maximum supply voltage for MC14082BDG, and what happens above that limit?

The absolute maximum DC supply voltage for MC14082BDG is +18.0 V, as specified in the Maximum Ratings table on page 1. Exceeding this voltage - even transiently - risks permanent damage. Stresses beyond −0.5 V to +18.0 V may degrade reliability or cause immediate failure, and device functionality is not guaranteed outside this range.

Are pins 6 and 13 on MC14082BDG truly no-connect (NC), and can they be left floating?

Yes, pins 6 and 13 on MC14082BDG are designated NC (no connection) per the PIN ASSIGNMENTS diagram on page 2 and the marking diagram notes. They are not bonded internally and may be left unconnected - no tie-down or routing is required. However, good PCB practice recommends avoiding long floating traces to reduce EMI pickup.

How should unused inputs on MC14082BDG be handled to ensure stable operation?

Unused inputs on MC14082BDG must be tied to a valid logic level - either VDD or VSS - as explicitly stated on page 4 under "Figure 1" notes and reiterated in the device description. Leaving them floating causes unpredictable output states, increased power consumption, and potential oscillation due to CMOS high-impedance inputs.

Is MC14082BDG pin-compatible with CD4082B devices, and what does "pin-for-pin replacement" mean here?

Yes, MC14082BDG is a pin-for-pin replacement for CD4082B-series devices, as confirmed in the Features section on page 1. This means identical pin assignments (including VDD, VSS, inputs, outputs, and NC pins), same SOIC-14 footprint, and compatible logic behavior - allowing direct substitution without PCB changes, provided supply and timing requirements align.
