The CD40103BE is a popular integrated circuit (IC) component, primarily used in digital logic circuits. It is a 16-pin counter and divide-by-eight binary ripple counter with a built-in oscillator. Here is an overview of its key features:
1. Binary Ripple Counter: The CD40103BE serves as a 4-bit binary counter, capable of counting from 0000 to 1111 (0 to 15 in decimal). It can function synchronously or asynchronously, depending on the input configuration.
2. Divide-by-Eight Counter: This IC can effectively divide the incoming clock signal by eight by utilizing its four flip-flops. This feature is particularly useful in timekeeping circuits and frequency division applications.
3. Oscillator: The CD40103BE incorporates a built-in oscillator that can generate a clock signal for the counter. The oscillation frequency is determined using external timing capacitors and resistors.
4. Cascading Capability: This IC has the ability to be cascaded with additional CD40103BEs or other compatible ICs to create larger binary counters or divide-by-eight counters. Cascading expands the counting range beyond 15 and increases the division factor.
5. Reset and Count Enable Pins: The CD40103BE includes a reset pin (active LOW) and a count enable pin (active HIGH). These pins allow for control over the counter's operation, enabling easy resetting or pausing of the count
