The CD4082BM is a dual 4-input AND gate from the 4000B CMOS logic family. Its 3V to 18V supply range means it can run from a single lithium cell through to a 12V industrial rail without a regulator — a real advantage in mixed-voltage or battery-backed designs where a 74HC part would need a separate 5V or 3.3V supply. With a maximum quiescent current of 1 µA, this gate adds negligible drain in always-on or sleep-mode circuits. The 90ns propagation delay at 15V and 50pF is typical for the 4000B family — adequate for slow control signals, pushbutton debounce, or enable gating where noise immunity matters more than speed.

Frequently asked questions
What is the equivalent of CD4082BM?
A close functional equivalent is the CD4025BM96, a triple 3-input NOR gate from the same 4000B series with the same 3V to 18V supply and -55°C to 125°C range. For a through-hole AND gate, the SN74HC21N offers a 2V to 6V supply and faster 19ns propagation delay, but with a narrower -40°C to 85°C temperature range.
