Key Features
- Synchronous Down Counter: The 74HC40103D decrements by one count on each positive-going transition of the clock (CP) input.
- Control Inputs: Includes inputs for enabling or disabling the clock, clearing the counter to its maximum count, and presetting the counter either synchronously or asynchronously.
- Terminal Count Output: The terminal count output (TC) goes LOW when the count reaches zero if the terminal enable input (TE) is LOW.
- Preset Capabilities: Data at the jam inputs (P0 to P7) can be clocked into the counter on the next positive-going clock transition or asynchronously forced into the counter.
- Operating Temperature Range: Specified from -40 °C to +125 °C.
Applications
- Divide-by-n Counters: Useful in applications requiring division of clock frequencies.
- Programmable Timers: Can be used in timer circuits where precise timing is required.
- Interrupt Timers: Suitable for generating interrupts at specific counts.
- Cycle/Program Counters: Used in various digital systems for counting cycles or programs.
- Automotive and Industrial Systems: Given its robust specifications, it is suitable for use in automotive, industrial, and other demanding environments.
