The CD54HC40103F is an integrated circuit (IC) component commonly used in digital electronic devices. It belongs to the HC family of high-speed CMOS logic devices and is specifically designed as a 4-bit synchronous up/down counter. Here is an overview of the CD54HC40103F and its key features:
1. Counter Function: The CD54HC40103F is primarily used as a binary counter. It can count in both up and down directions based on the input signal given to its control pins.
2. Synchronous Operation: It operates synchronously, meaning that the outputs change only when a clock signal is received. This feature allows precise timing of count events.
3. 4-Bit Counter: The IC has a 4-bit counter, allowing it to count from 0 to 15 (in binary) or 0 to 9 (in decimal). It can count in both ascending and descending order based on the input signals.
4. Asynchronous Load Capability: The CD54HC40103F also supports asynchronous loading. This feature allows the loading of a specific value into the counter without affecting its current state or count sequence.
5. Ripple Clock Output: An additional output pin, called the ripple clock (RCO) output, is provided. It carries the carry/borrow pulse generated during counting. This output can be used to cascade multiple CD54HC40103F ICs in order to increase the counting range
