The MC100EL32MNR4G is a 8-bit presettable counter that features unconditional CON/NOP/LD operations across all of its modes. What makes this particular chip unique is that it can divide by any number from 2-3-4-5-7, as well as a custom N number when needed. It has both asynchronous (RESET) and synchronous (CLR) inputs, as well as connections to external components such as ROMs, ROMUPs (which enable the presetting of the counter), and flip-flops.

The main application field for this chip is found in high speed counting applications, such as in the automotive industry or vending machines. This chip can also be used for frequency division and divider chain circuits, where it can provide reliable and stable performance. It is primarily used in commercial and industrial applications.

When it comes to the working principle of the MC100EL32MNR4G, it operates on the basis of a binary ripple counter. This means that each flip-flop is triggered on a rising or falling signal, which causes the counter to increment or decrement its value. The chip itself is a synchronous 8-bit ripple counter, which means that each clock signal causes the counter to increment its value by 1. This can be customized to achieve the needs of the application by adding a specific pulse width, allowing the user to control the number of pulses in a given time period.

In terms of its functionality, the MC100EL32MNR4G can be used as a 1-of-N binary counter, dividing a signal with N pulses into N equal-sized pulses, as well as a frequency divider, which allows for high-speed counting operations. The chip can also be used as a divider-chain circuit, which is a type of digital circuit that has multiple stages of flip-flops interconnected to form a digital clock. This allows the user to create complex patterns of high-speed clock signals.

Overall, the MC100EL32MNR4G presettable counter is a versatile and reliable digital solution for a variety of industrial and commercial applications. Its asynchronous or synchronous reset inputs and preload options make it suitable for a wide range of applications, such as frequency division and divider chain circuits. Additionally, its binary ripple counter principle allows it to provide high-speed counting operations. This makes it an ideal choice for applications where reliability and speed are critical.
