CD4085BE is a multi-function, configurable logic chip, is the major part of the CMOS logic family. It is widely used in digital circuits, from simple logic gates and to more complex circuits such as microprocessors and memory controllers.

CD4085BE is a 8 pin dual 4-input NAND gate. It can accept up to four inputs, plus an enable signal, and produce a single output. Specifically, it behaves like four independent 1-input NAND gates, with the additional enable allowing the user to select which of the four NAND gates will have an output. It can be used in single-ended or dual-in-line packages, allowing it to easily fit into a wide variety of digital circuits.

The primary use of the CD4085BE is as a logic gate. It is a very versatile device, capable of performing many different functions. It can be used to build simple logic gates, flip flops, memory chips, registers, counters, and more. It is also a great choice for constructing custom logic-based designs, as it is both flexible and affordable.

The working principle of the CD4085BE is based on a combination of CMOS transistors and logic gates. The two transistors in each NAND gate are cross-coupled, meaning that one transistor acts as a switch and the other acts as an inverter. When an external signal is applied to the NAND gate, the switch is turned on, producing a logical “1” output, and the inverter is turned off, resulting in a logical “0”.

In addition to being used as a logic gate, the CD4085BE can also be used to construct arithmetic logic units (ALUs), programmable logic arrays (PLAs), multiplexers, and counters. Many modern digital systems make use of these components, as they are very useful and efficient.

Overall, the CD4085BE is an extremely useful and versatile chip, capable of performing many different functions. Its low price tag and wide availability make it an ideal choice for use in many digital circuits.
