The HCF4040M013TR is an IC (integrated circuit) component manufactured by STMicroelectronics. It is a 12-stage binary counter that can be used in various applications such as frequency division, time delay generation, and digital clock generation.
Key Features:
1. Binary Counter: The HCF4040M013TR functions as a 12-stage binary counter, which means it can count up to 4095 cycles before it rolls over to zero. This makes it suitable for applications where counting and timekeeping are required.
2. Ripple Carry Output: It offers a ripple carry output (RCO) that allows cascading multiple counters for extended counting capabilities. This feature enables the creation of larger counters by connecting multiple ICs in series.
3. Synchronous Operation: The HCF4040M013TR operates in a synchronous manner, which means all the flip-flops within the counter change their state simultaneously at the clock input edge. This ensures accurate and synchronized counting across all stages.
4. Clock Enable Function: It comes with a clock enable input (CEN) that allows the user to start or stop the counting operation. When the clock enable is high, the counter advances on each clock pulse, and when it is low, the count remains unchanged.
5. Schmitt Trigger Inputs: The IC features Schmitt trigger inputs on both clock and reset pins. These inputs help eliminate noise and provide hysteresis, ensuring reliable and stable operation in noisy environments
