STMicroelectronics M74HC4520RM13TR Dual Binary Counter

The M74HC4520RM13TR is a high-performance integrated circuit from STMicroelectronics, renowned for its reliability and efficiency in a wide range of electronic applications. This dual binary counter is part of the HC family, which signifies its compatibility with high-speed CMOS technology. The device is designed to operate with a power supply range of 2V to 6V, making it versatile for use in both low and standard voltage operations.

Encased in a compact SOP-16 package, the M74HC4520RM13TR offers a space-saving solution for your circuit designs without compromising on functionality. The device features two independent counters, each with a divide-by-two section and a divide-by-five section. These sections can be connected in various configurations such as divide-by-10, divide-by-20, or even higher division ratios, providing flexibility in creating timing circuits, frequency dividers, and counters for a plethora of applications.

Each counter has a dedicated clock input (nCP0 and nCP1), a master reset input (nMR), and outputs for both the divide-by-two (nQ0 to nQ3) and divide-by-five (nQ0 to nQ3) sections. The master reset input enables the resetting of the counters to zero, ensuring precise control over timing sequences. The clock inputs are designed to trigger on the rising edge of the clock pulse, ensuring accurate and predictable counting transitions.

The M74HC4520RM13TR is characterized by its high noise immunity and low power consumption, which are hallmarks of CMOS technology. These features make the device ideally suited for use in portable and battery-powered devices where power efficiency is crucial. Additionally, the counter is fabricated with silicon gate C2MOS technology, ensuring robust performance and protection against latch-up.

With its ability to interface with TTL levels, the M74HC4520RM13TR is easily integrated into mixed-technology environments, bridging the gap between CMOS and TTL systems. The device is also provided in tape and reel packaging, denoted by the TR suffix, which facilitates automated assembly processes for high-volume production.

In summary, the M74HC4520RM13TR from STMicroelectronics is a versatile and reliable choice for designers looking to implement efficient counting and timing solutions in their electronic systems.
