What are the key features of CD4082BF?
- Dual 4-input AND gate with CMOS 4000-series compatibility operating from 3V to 18V supply for wide voltage range logic applications
- 50 pF load capacitance rating with 1.5 mA output drive current supporting standard CMOS logic level interfacing in digital control circuits
- Ceramic DIP-14 package providing enhanced reliability and temperature stability for military, aerospace, and high-reliability industrial applications
What is CD4082BF used for?
The CD4082BF is used in combinational logic circuits where 4-input AND gating is required, such as address decoding, enable signal generation, and multi-condition logic qualification in industrial control systems. Its wide supply voltage range from 3V to 18V makes it compatible with both legacy 5V TTL-compatible systems and modern 3.3V logic designs. The ceramic DIP-14 package is favored in military, aerospace, and high-reliability industrial environments where temperature cycling and long-term component stability are critical.

Frequently Asked Questions
What supply voltage range does CD4082BF support and how does it compare to standard TTL logic?
CD4082BF operates across a supply voltage range of 3V to 18V, far wider than standard TTL logic which is limited to 5V. This makes it compatible with both legacy 5V systems and modern 3.3V designs, allowing it to interface directly with various logic families without level shifters in mixed-voltage digital systems.
Why is the ceramic DIP-14 package of CD4082BF chosen for aerospace or military logic circuits?
The ceramic DIP-14 package of CD4082BF provides superior hermeticity and thermal stability compared to plastic packages, making it the preferred choice for aerospace, military, and high-reliability industrial circuits. Ceramic packaging resists moisture ingress and maintains electrical integrity across wide temperature ranges typically from -55°C to 125°C, meeting MIL-spec qualification requirements.
How many inputs and independent AND gate elements does CD4082BF provide on a single chip?
CD4082BF contains 2 independent 4-input AND gate elements in a single 14-pin package, with each gate accepting 4 logic inputs and producing one output. This allows complex multi-condition logic qualification — such as 4-signal coincidence detection or address decoding — without requiring multiple gate ICs or discrete logic combinations.
In what combinational logic or address decoding designs does CD4082BF simplify circuit implementation?
CD4082BF simplifies designs where multiple conditions must be simultaneously true before enabling an output, such as 4-bit address decoding, chip-enable qualification in memory systems, or multi-sensor alarm logic. Its dual 4-input AND structure with 50 pF load rating allows direct connection to standard CMOS or TTL logic bus lines without additional buffering in moderate fan-out designs.
