Dual 4-input AND gate in the 4000B family
The CD4082BE is a dual 4-input AND gate from Texas Instruments' 4000B series, packaged in a 14-DIP through-hole format. It contains two independent AND gates, each with four inputs, and operates across a 3V to 18V supply range.
Temperature grade and quiescent draw
Quiescent current is 1 µA maximum, so the gate adds negligible standby drain in a battery-powered system.
There is no announced last-time-buy window or successor part — the 4000B series remains a catalog staple for low-speed, wide-voltage logic. The through-hole 14-DIP package (0.300-inch row spacing) is a standard breadboard-friendly footprint.
