ON Semiconductor MC74HC4040AD: High-Speed CMOS Logic 12-Stage Binary Ripple Counter

The MC74HC4040AD is a high-performance integrated circuit produced by ON Semiconductor, designed to function as a 12-stage binary ripple counter. Built using advanced high-speed CMOS technology, this device is a part of the 74HC series, which is well-known for its robust performance and compatibility with a wide range of digital systems.

This binary counter features a 12-stage ripple-carry binary counter structure, which allows it to provide sequential counting operations with high precision and reliability. The MC74HC4040AD is ideal for applications requiring accurate time delays or frequency division, as it is capable of handling clock frequencies ranging from DC up to 24MHz for V<sub>CC = 4.5V, 48MHz for V<sub>CC = 6.0V, and 72MHz for V<sub>CC = 10V.

With its wide operating voltage range of 2V to 6V, the MC74HC4040AD offers great flexibility, making it suitable for battery-operated devices as well as for more demanding electrical environments. Furthermore, its low power consumption and high noise immunity are characteristics inherent to the CMOS technology, ensuring that the device operates efficiently and reliably even in electrically noisy conditions.

The counter advances on the negative-going edge of the clock signal, which is applied to the CP input while the RESET input is held low. When the RESET input is taken high, the counter is reset to zero, regardless of the state of the clock input. This feature allows for synchronous reset capability, which is critical for many digital applications.

The MC74HC4040AD is offered in a compact SOP-16 package, making it suitable for space-constrained applications. Its pin configuration is standardized, ensuring ease of integration into existing designs without the need for significant layout changes.

In summary, the ON Semiconductor MC74HC4040AD is a versatile and reliable component that is an excellent choice for designers looking to implement a high-speed binary ripple counter in their digital systems. Its combination of high-speed operation, low power consumption, and robust noise immunity makes it an ideal choice for a wide range of counting applications.
