Frequently Asked Questions
How many outputs does the CD74HC4017NSR have and what type of counter is it?
The CD74HC4017NSR is a Johnson decade ring counter with 10 individually decoded outputs. Each clock pulse advances the active high output to the next output pin in sequence, cycling through all 10 outputs before returning to the first, making external decoding unnecessary.
What is the gated clock feature of the CD74HC4017NSR?
The gated clock input allows the counting sequence to be enabled or disabled synchronously, giving designers control over when the counter advances. This is useful in applications like LED sequencers, multiplexers, and timer circuits where the counting must start or stop on demand.
What logic family and package does the CD74HC4017NSR use?
It belongs to the HC/UH high-speed CMOS logic family and is housed in a 16-pin SOIC surface-mount package (JESD-30 code R-PDSO-G16), suitable for automated PCB assembly with a 50 pF rated load capacitance.
Is the CD74HC4017NSR RoHS compliant?
Yes, the CD74HC4017NSR is RoHS and lead-free compliant (JESD-609 code e4, Pbfree Code: Yes), making it suitable for environmentally conscious designs and compliant with international regulations on hazardous substances in electronics.
What are typical applications for the CD74HC4017NSR?
Typical applications include sequential LED chasers, frequency division circuits, decade timers, tone burst generators, industrial automation sequencers, and any circuit requiring 10-step sequential output control driven by a clock or pulse source.
