HD74HC4520P

The HD74HC4520P is a dual 4-bit synchronous binary counter, designed for high-speed digital counting applications. Each counter within the IC consists of four D-type flip-flops, which operate synchronously on the positive edge of the clock signal. This allows for reliable binary counting and frequency division. With an operating voltage range of 2V to 6V, the HD74HC4520P ensures broad compatibility with low-power and standard CMOS logic families. The maximum count rate of 9 MHz makes it suitable for fast digital applications, frequency division, and automation systems. The asynchronous reset input allows for immediate counter clearing, ensuring precise control over counting sequences. Its DIP-16 package allows for easy breadboard integration, through-hole PCB assembly, and digital circuit implementations.
