CD4081BE DIP-14 CMOS Quad 2-Input AND Gate IC 5PCS | 3–18V Logic

CD4081BE — DIP-14 CMOS Quad 2-Input AND Gate IC (5PCS)

The CD4081BE is a classic CMOS quad 2-input AND gate IC in a standard DIP-14 package. Containing four independent 2-input AND gates, it operates across a wide 3V to 18V supply range — making it compatible with both 3.3V and 5V microcontroller systems. Its ultra-low quiescent current and high noise immunity make it ideal for battery-powered logic circuits, signal gating, and digital control applications.
