The CD4522BNSRG4 is an 8-bit static counter divider with a positive edge-triggered clock input. It is suitable for usage as a frequency divider, sample-and-hold circuit, or as a divide-by-N circuit with a frequency of operation up to 10 kHz, depending on the application. It is available in the standard 20-pin SOIC, PDIP or small-outline LCC packages.

The CD4522BNSRG4 is a versatile 8-bit static counter divider with an edge-triggered clock input. It is capable of counting to 255 or dividing an input frequency by up to 255. Counting and dividing is accomplished by means of an asynchronous reset terminal (RST) and a pulse rate terminal (PRD) as well as independent clock inputs (CLK1 and CLK2). The CD4522BNSRG4 is capable of a wide range of operating frequencies, from DC to 10 kHz. It is available in three different packages, 20-pin SOIC, PDIP, and small-outline LCC. This makes it suitable for use in a wide range of applications.

The CD4522BNSRG4 can be used as a frequency divider, sample-and-hold circuit, or divide-by-N circuit. It can be used for generating low-frequency signals such as pulse generator, sawtooth generator, and sweep generator. It is ideal for clock and frequency division, as well as time base generation and time delay applications.

In the frequency divider application of the CD4522BNSRG4, the input clock frequency is divided by the value programmed by its pulse rate (PRD) terminal. This input clock is then earthed through the RST terminal. Counter circuitry within the CD4522BNSRG4 divides the input frequency by decrementing the PRD value until it reaches zero. At this point, the counter is reset and starts counting again.

In the sample-and-hold application, the CD4522BNSRG4 is used to sample the input signal and hold it for a certain period of time. The input clock is used to trigger the start of the sampling cycle, and the value programmed by the PRD terminal is used to determine the length of the sampling period. When the PRD reaches zero, the output signal is held for as long as the RST terminal is held low. When the RST terminal is released, the cycle is reset and the sampling begins again.

Finally, in the divide-by-N application, the CD4522BNSRG4 is used to divide the input signal frequency by a programmed value. This can be used for generating low frequency signals such as pulse generators, sawtooth generators, and sweep generators. The input signal is passed through the CLK1 terminal and the desired frequency is programmed via the PRD terminal. The output frequency is equal to the input frequency divided by the PRD value.

In conclusion, the CD4522BNSRG4 is an 8-bit static counter divider with a positive edge-triggered clock input. It is suitable for frequency division, sample-and-hold, and divide-by-N applications with a frequency of up to 10 kHz. It is available in the 20-pin SOIC, PDIP, and small-outline LCC packages, making it suitable for a wide range of applications. With its versatile design and wide operating frequency range, the CD4522BNSRG4 is a great choice for applications needing low-frequency signals.
