MM74HC161M

The MM74HC161M is an integrated circuit (IC) component that belongs to the 74HC family of high-speed CMOS logic devices. It is a synchronous, presettable, and binary counter designed to count up to 16 different binary sequences. The IC is commonly used in a wide range of digital applications, including computers, calculators, registers, and digital signal processing systems. Key Features of the MM74HC161M: 1. Synchronous Counting: The IC features synchronous counting functionality, meaning all the flip-flops within the device advance their state simultaneously on each clock pulse. This ensures accurate and coordinated counting. 2. Presettable Counter: The MM74HC161M is a presettable counter, allowing users to load a specific value into the counter by applying the desired binary code to preset inputs (P0, P1, P2, P3). This feature enables flexible count configurations and facilitates specific count sequences. 3. Binary Counting: The IC can count in binary sequences from 0 to 15 (or vice versa) as per the clock input and control signals. It operates in a divide-by-16 mode, providing 4-bit binary output (Q0, Q1, Q2, Q3) representing the current count value. 4. Asynchronous Parallel Load: The MM74HC161M offers an asynchronous parallel load capability through the asynchronously preset inputs
