4017 Counter Ic Datasheet !!link!! Link

With an RC network on the clock input, the 4017 can cleanly register mechanical switch presses.

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). 4017 counter ic datasheet

The 4017 is part of the 4000B series, which operates over a wide voltage range (3V to 18V). Key specifications from the datasheet include: With an RC network on the clock input,

A critical timing parameter from the datasheet is the (typically 60–120 ns at 10V). This delay defines how quickly the outputs change after a clock edge, limiting the maximum clock frequency to around 5–10 MHz depending on supply voltage. The 4017 is part of the 4000B series,

The 4017 is a 5-stage Johnson counter that converts a clock input into a sequence of 10 high-state outputs.

In the vast landscape of digital integrated circuits, few components have achieved the legendary status of the . Introduced as part of the 4000-series CMOS logic family, the 4017 is a decade counter with integrated 10-output decoding. A careful reading of its datasheet reveals not just a collection of electrical specifications, but a blueprint for sequential logic that has powered countless LED chasers, sequencers, and timing circuits for over five decades.
