BCD counter for frequency counter

The CD4518 DIP Dual BCD Counter is a CMOS IC featuring two independent 4-bit BCD counters, capable of counting from 0 to 9 in binary-coded decimal format. It offers BCD outputs, making it ideal for use in digital clocks, frequency counters, and seven-segment displays. With enable and clear inputs, it provides flexible control over the counting process. Operating over a wide voltage range (3V to 18V) and packaged in a DIP-16 format, the CD4518 is a versatile and energy-efficient solution for counting and display applications.
