Frequently Asked Questions
What counting mode does the CD4522BMT operate in?
The CD4522BMT operates as a down counter, decrementing from a preset value to zero in BCD decade format. It features a Load/Preset input that allows programming the starting count value, enabling flexible countdown sequences from any value between 0 and 9.
What is the package type for the CD4522BMT?
The CD4522BMT is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) surface-mount package. The 'MT' suffix in the part number indicates this tape-and-reel packaging for automated assembly processes, suitable for high-volume production applications.
What supply voltage range does the CD4522BMT support?
As part of the 4000/14000/40000 CMOS logic family, the CD4522BMT supports a wide supply voltage range from approximately 3V to 15V. This flexibility allows it to operate in both low-voltage battery systems and standard 5V or 12V industrial control environments.
Can CD4522BMT counters be cascaded for larger count ranges?
Yes, the CD4522BMT includes a carry cascade output that allows multiple units to be chained together for extended counting ranges. By connecting the carry out of one stage to the cascade input of the next, designers can create multi-decade down counters for applications requiring counts beyond a single decade.
What are typical applications for the CD4522BMT?
The CD4522BMT is commonly used in frequency division, digital timing circuits, and industrial process control applications that require programmable countdown sequences. It is also used in BCD display driving systems, event counters in test equipment, and motor control sequencing circuits where decimal counting representation is needed.
