The CD4012BE is an integrated circuit (IC) manufactured by Texas Instruments. It is a dual 4-input NAND gate, meaning it has two NAND gates each with four inputs. This allows the two gates to be used independently or together, making it an ideal choice for applications requiring logic-level functions, such as logic gates and logic switching. The IC is designed with extremely low-current drain and high noise immunity, making it ideal for battery-powered devices such as cell phones. The CD4012BE is available in both through-hole DIP and surface-mount SOIC packages.
