CD4048BE

Description

The CD4048BE is a multifunction CMOS gate capable of performing eight different logic operations—such as AND, OR, NAND, NOR, OR-AND, OR-NAND, AND-OR, and AND-NOR—selected via three control inputs. A fourth control input enables three-state output, which allows the chip to interface with shared bus lines. It also includes an EXPAND input, enabling cascading of additional gates to combine multiple units into a larger logic structure (e.g., two chips yield a 16-input gate). Operable from a wide voltage range of 3 V to 18 V DC, this device provides robust logic functionality with low power consumption, making it suitable for various digital applications in industrial, educational, and embedded systems.
