What are the key features of CD74HC4017M?
- Johnson counter with 10 fully decoded active-high outputs, producing one active output per clock cycle for direct LED or relay drive
- Gated clock enable input allowing the counter to be paused mid-sequence without resetting, enabling flexible timing control
- Up to 20 MHz clock frequency at 5 V with 50 pF load, covering audio frequency sequencing up to ultrasonic timing applications
What is CD74HC4017M used for?
The CD74HC4017M is used in LED chaser light sequencers, decade frequency dividers, and event multiplexing circuits that require stepping through 10 discrete outputs one at a time. Its decoded outputs eliminate the need for a separate decoder IC, directly driving 10 LEDs, relays, or logic inputs in sequence from a single clock source. The 2 V to 6 V supply range and SOIC packaging make it suitable for battery-powered consumer gadgets, educational kits, and industrial panel indicator systems.

Frequently Asked Questions
How does the Johnson counter architecture of CD74HC4017M produce 10 decoded outputs from a single clock input?
The CD74HC4017M internally uses a 5-stage Johnson shift register whose states are decoded by combinational logic to produce 10 unique active-high outputs, one per clock cycle, before the sequence repeats. Each output is high for exactly one clock period, giving a duty cycle of 10% at any output pin. This architecture requires no external decoder, saving at least one additional IC compared to a binary counter plus 4-to-10 decoder approach.
At what clock frequency does the CD74HC4017M operate and what LED scanning rate does this enable?
The CD74HC4017M clocks up to 20 MHz at 5 V supply with 50 pF load. For an LED chaser with 10 outputs, each LED illuminates for one clock period, so at 20 MHz the full sequence repeats 2 million times per second — far above the 50 Hz flicker threshold. For visible LED animation, typical designs use clock rates between 10 Hz and 100 Hz, giving LED scan periods of 100 ms to 10 ms per step.
How does the gated clock enable input of CD74HC4017M enable event-triggered counting applications?
The CD74HC4017M has a clock enable (CE) input that freezes the counter at its current state when held high, without resetting or corrupting the count. This allows the counter to act as a step sequencer that advances only while an external trigger is active, such as advancing one step per button press or per detected object on a conveyor belt sensor. The separate master reset (MR) pin independently returns the counter to output Q0 when asserted.
When would a designer choose CD74HC4017M over a 74HC163 binary counter for a 10-step sequencer application?
CD74HC4017M provides 10 decoded active-high outputs directly, eliminating the 4-to-10 decoder IC needed when using a 74HC163 binary counter. For a 10-step sequencer driving 10 individual loads, the CD74HC4017M solution uses 1 IC versus at least 2 ICs with 74HC163 plus 74HC42 decoder, saving approximately 40% PCB area and 50% component cost. The trade-off is that CD74HC4017M is fixed at 10 steps while 74HC163 can be configured for 2–16 steps.
