The MM74HC4040N is an integrated circuit (IC) component that belongs to the HC family of high-speed CMOS logic. It is specifically designed as a counter with a binary ripple carry output. This IC offers several key features that make it well-suited for various digital electronics applications.
One of the primary features of the MM74HC4040N is its ability to perform ripple counting, which means that it sequentially counts from 0 to 4095 (or hexadecimal FFF) and then repeats. This counter has a total of 12 stages, allowing it to provide a 12-bit output. The binary ripple carry output can be used to cascade multiple MM74HC4040N ICs, enabling the counting range to be extended beyond 4095.
Another important feature of this IC component is its high-speed operation. The MM74HC4040N can function at a frequency range of up to 64 MHz, making it suitable for applications that require rapid counting or timing functions. Its high-speed capabilities make it compatible with a wide range of digital systems and microcontrollers.
The MM74HC4040N also offers asynchronous master-reset capability. This means that a RESET signal can be applied to the counter, which resets it to its initial state. This feature is useful when a user wants to synchronize the counter to a specific event or starting point
