HCF4017BE 5-stage Johnson counter
The HCF4017BE is a CMOS 5-stage Johnson decade counter/divider with 10 decoded outputs. It sequentially activates one output per clock pulse, ideal for LED chasers, sequence generators, frequency division, and timing applications in digital electronics.
يُعدّ HCF4017BE عدّاد/مقسّم Johnson من نوع CMOS مكوّن من 5 مراحل وعشري المخرجات (5-stage Johnson decade counter/divider) مع 10 مخارج مفككة (decoded outputs). يقوم بتنشيط مخرج واحد بالتتابع مع كل نبضة ساعة، مما يجعله مثاليًا لتطبيقات LED chasers، ومولّدات التسلسل، وتقسيم التردد، وتطبيقات التوقيت في الإلكترونيات الرقمية.
The HCF4017BE is a high-speed CMOS Johnson decade counter with ten output pins (Q0–Q9) and a carry-out. It counts on the rising edge of the clock input and provides sequential activation of each output. The counter can be reset asynchronously, making it suitable for timing, sequencing, and display applications.
