HEF4521BP,652

The IC component HEF4521BP,652 is a versatile and widely used integrated circuit (IC) that offers programmable binary counter functionality. It is manufactured by NXP Semiconductors and is a part of the HEF4520 series. Key Features: 1. Binary Counter: The HEF4521BP,652 is a 24-stage, binary ripple counter that can be programmed by the user to provide different counting sequences. 2. Programmable Inputs: The IC offers four configuration inputs, labeled A, B, C, and D. These inputs allow the user to select the desired counting sequence. 3. Count Enable and Reset: The IC features a count enable input (CE), which allows for counting to occur only when it is enabled, and a reset input (MR), which resets the counter to its initial state. 4. Input Ripple Blanking: The IC includes an input ripple blanking feature that ensures reliable counting operation even with slow or noisy input signals. 5. Buffered Outputs: The IC provides four buffered outputs, labeled Q0, Q1, Q2, and Q3. These outputs reflect the current state of the counter and can be used for further processing or driving external devices. 6. Wide Operating Voltage Range: The IC is designed to operate over a wide supply voltage range of 3 V to 15 V, making it suitable for various applications
