What are the key features of CD74HC40103MG4?
- 8-bit synchronous binary down counter with terminal count output (TCO) for cascading and end-of-count detection in multi-stage timing circuits
- Synchronous preset load and reset-to-max-count inputs allow programmable count intervals from 1 to 255 cycles without external glitch-prone asynchronous resets
- HC CMOS logic family with 2 V to 6 V supply range and 10 MHz maximum clock frequency for versatile low-power digital timing applications
What is CD74HC40103MG4 used for?
CD74HC40103MG4 is used in programmable timers, frequency dividers, event counters, and watchdog timeout circuits where a precise 8-bit synchronous down count to zero is needed with a clean terminal count output pulse. Its synchronous load input also makes it suitable for pulse-width generation and sequencing logic in industrial PLCs, robotics controllers, and embedded motor-drive timing circuits operating from 3.3 V or 5 V digital rails.
