The 74HC40103 is an 8-bit synchronous binary down counter IC designed for counting applications in digital systems. It counts down from a preset value and provides an output when it reaches zero. This IC is widely used in timers, frequency dividers, and other counting-related applications. The IC is available in an SMD package, making it ideal for compact and space-efficient designs.
Features
- 8-Bit Synchronous Binary Down Counter: Provides an 8-bit counting capability with synchronous operation, meaning all bits are updated simultaneously with the clock signal.
- Programmable Load Function: Allows the counter to be preset to any value, from which it will count down.
- Zero Detection Output: Includes a terminal that goes low when the counter reaches zero, enabling it to signal the end of a counting sequence or trigger other events in the system.
- High-Speed Operation: Capable of operating at high speeds, making it suitable for fast counting applications.
- Synchronous Clear Function: Allows the counter to be reset synchronously with the clock signal.
- SMD Package: Available in various surface-mount packages, such as SOIC, TSSOP, etc., ideal for integration into high-density PCB designs.
