Frequently Asked Questions
What is the maximum operating frequency of the CD4520BM?
The CD4520BM can operate at a maximum frequency of 1.5 MHz (1,500,000 Hz) at its nominal supply voltage. This makes it suitable for medium-speed digital counting and frequency division applications in industrial and consumer electronics.
What supply voltage range does the CD4520BM support?
The CD4520BM supports a wide supply voltage range from 3V to 18V, making it highly versatile for both low-power battery-operated devices and standard 5V or 12V logic systems. This wide range is characteristic of the 4000-series CMOS logic family.
What package type is the CD4520BM available in?
The CD4520BM comes in a 16-pin SOIC (Small Outline Integrated Circuit) package, which is compact and suitable for surface-mount PCB designs. This package type is widely available and compatible with automated assembly processes.
What are typical applications for the CD4520BM?
Typical applications include digital event counters, clock frequency dividers, industrial timers, sequencing circuits, and frequency synthesizers. Its noise-resistant Schmitt trigger clock input makes it ideal for use in environments with electrical interference, such as automotive and industrial control systems.
Is the CD4520BM a drop-in replacement for other 4000-series counters?
The CD4520BM is part of the standard 4000/14000/40000 CMOS logic family, so it is functionally compatible with equivalent parts from other manufacturers such as HEF4520B or MC14520B. Always verify supply voltage, timing parameters, and package pinout before substituting in a design.
