4017 Counter Ic Datasheet Jun 2026

A 555 timer generates clock pulses, and each output lights an LED in sequence. The reset pin can be wired to any output to create shorter sequences (e.g., Q4 to reset for a 0–3 sequence).

The CD4017 is a high-speed CMOS decade counter/divider renowned for its versatility in low-range counting applications. Often referred to as a , it features ten decoded outputs that activate sequentially with each rising edge of a clock signal. Core Technical Specifications 4017 counter ic datasheet

By connecting the carry-out of one 4017 to the clock of a second, a 10×10 = 100-step counter is created. This is used in music sequencers and industrial timing. A 555 timer generates clock pulses, and each

Any output can be fed back to reset, yielding division ratios from 1/2 to 1/10. A 555 timer generates clock pulses
