CD4025BEG4 is a member of the Quad Bilateral Switch and is part of the family of Logic - Gates and Inverters. It has three digital input terminals and two output terminals, which can be used to switch between logic levels. The inputs, which can be connected to ASICs and other digital sources, will drive the commonly used logic levels of 0 and 1.

CD4025BEG4 plays an important role in logic circuits like Boolean logic, NAND and NOR logic, and sequential logic. Its applications include industrial automation and control, home automation systems, data processing systems, automotive systems, medical systems, and robotics systems.

CD4025BEG4 works by evaluating the logic level of the input signals. If both inputs are the same, the output will present the same logic level as the input. If the inputs are different, the output will be opposite from the input. This function is called symmetrical transfer. It is useful in motor control and power switch applications, where it is important to detect the difference between the two level inputs.

The working principle of CD4025BEG4 is based on the concept of pass-transistor. It is a four-trace NAND gate with three digital inputs and two active low outputs. The output of the NAND gate will be high if one of the input is low, and will be low only when all the inputs are high. That is why the output of the NAND gate will present the inverse of the input signals.

A pass transistor circuit also exists in CD4025BEG4. The circuit consists of two NMOS transistors and two PMOS transistors. The NMOS transistors serve as switches for the input signals, and the PMOS transistors are used for the outputs. When the logic level of the inputs is low, the NMOS transistors will be on and can deliver the signals to the output. When the logic level of the inputs is high, the PMOS transistors will conduct, thus producing the inverse logic output.

The CD4025BEG4 has a wide operating temperature range from -55°C to 125°C. It also has a fast switching time (tpd = 350 ns), delivering fast data transfer in applications. It also has an output control system to address issues related to floating outputs. Moreover, it comes in a package of SC70-5 and is widely used in integrated circuits, test and monitoring instruments, and other applications.

CD4025BEG4 operates in a very simple way yet it is capable of providing reliable and high performance logic functions. It can be used to perform digital logic operations, such as Boolean logic, NAND and NOR logic, and sequential logic. This makes it extremely versatile and widely used in different automation and control systems, as well as complex data processing systems. It also features a wide operating temperature range, as well as a fast switching time, making it an ideal choice for various applications.
