Logic Integrated Circuits (ICs) are used in most electronic appliances and devices. They are used to control the flow of electricity and the signals that they receive. One of the most popular logic ICs is the CD4522BE, which provides users with a variety of functions and applications. This article will discuss the application field and working principle of the CD4522BE.

The CD4522BE is a dual BCD up / down counter. It is used in a variety of applications such as digital clocks, metering and timer circuits. The CD4522BE includes two BCD up / down counter sections, which can both be used to form a range of different counting functions. The CD4522BE also contains a latch, which is used to store the counted result.

The CD4522BE is designed to work on either 3V or 5V power supplies. The CD4522BE has an input frequency range of 1Hz to 10kHz and can also be used as a divide-by-n counter. In addition, the CD4522BE has a built in voltage regulator which allows it to work over the specified operating temperature range. The CD4522BE is also able to detect logic 1 signals at TTL levels, which makes it suitable for signal processing applications.

The working principle of the CD4522BE is quite simple. It is a BCD up/down counter that counts up or down when a clock signal, falling edge or rising edge pulse is applied to its clock input terminal. The BCD up/down counter operates in conjunction with an integrated latch, which stores the counted result in the logic levels 0s and 1s. When the counter reaches its maximum value of nine or its minimum value of zero, it will start to count the other way.

The CD4522BE can also be used for divide-by-n counting. For example, to divide a signal by 8, the counter should be connected to the clock signal as shown below:

In this diagram, the input is connected to the clock input of the counter and the output is connected to the clock of the next stage. The counter will count from 0 to 7 (the maximum number) and then reset back to 0 and start counting again. This way, the signal is divided by 8, which results in an output of 1 pulse for every 8 input pulses.

To sum up, the CD4522BE is a popular logic IC that is used in a variety of applications. It is a dual BCD up/down counter and is used in applications such as digital clocks and metering. In addition, the CD4522BE has a built in voltage regulator and can be used as a divide-by-n counter. Its working principle is relatively simple, as it is designed to count up or down when a clock signal, falling edge or rising edge pulse is applied to its clock input terminal.
