Frequently Asked Questions
How fast can the CD74HC4017PW clock input run in a frequency divider application?
The CD74HC4017PW supports a maximum clock frequency of 20 MHz at nominal supply voltage with a 50 pF load capacitance, making it suitable as a divide-by-10 prescaler in frequency counters, clock trees, and digital timing circuits operating in the low megahertz range.
How many outputs does the CD74HC4017PW provide, and can they drive LEDs directly?
The CD74HC4017PW provides 10 fully decoded individual outputs, one active-high at a time, advancing sequentially with each clock pulse; the HC-family CMOS outputs can source or sink up to 25 mA per pin, sufficient to drive standard 5 mm LEDs at 10 mA to 20 mA without series-resistor buffers in 5 V systems.
What is the package footprint of the CD74HC4017PW and how does TSSOP-16 compare to DIP alternatives?
The CD74HC4017PW uses a 16-pin TSSOP package with approximately 5.0 mm x 4.4 mm body and 0.65 mm pin pitch, versus a DIP-16 footprint of 19.6 mm x 7.0 mm; the TSSOP saves over 80% of PCB area, making it the preferred choice for compact surface-mount boards in modern consumer and industrial designs.
How does the gated clock input of the CD74HC4017PW enable multi-stage cascade configurations?
The CD74HC4017PW's active-low clock enable (CE) input halts counting when driven high, allowing cascade of multiple CD74HC4017PW devices so that one stage's carry-out pin drives the next stage's clock, creating decade-multiplied counters such as 100-step or 1000-step sequencers from 2 or 3 ICs without additional gating logic.
