Product Overview: CD4017B Decade Counter/Divider

The CD4017B is a highly versatile decade counter/divider integrated circuit from Texas Instruments, renowned for its reliability and flexibility in various electronic applications. This IC is part of the 4000 series CMOS logic family and is designed to work with a 3 to 18V supply voltage, making it suitable for both hobbyist and professional projects.

At the heart of the CD4017B lies its ability to count pulses. It has a 5-stage Johnson decade counter with ten decoded outputs, meaning it can count from 0 to 9 in sequential order. Each output represents one of the ten states, which become high (logic 1) in succession as pulses are received at the clock input. This feature makes the CD4017B ideal for creating a variety of sequential logic circuits, including counters, frequency dividers, and event-driven state machines.

The CD4017B also includes a reset function, which allows the counter to be quickly reset to zero (00000) or any other pre-set value. This is extremely useful in applications where precise timing or counting is crucial. Additionally, the carry-out signal provides a pulse output once every ten clock input pulses, which is useful for cascading multiple CD4017B counters for extended counting ranges.

With its Schmitt-triggered clock input, the CD4017B ensures high noise immunity and stable counting for slow-rising or slow-falling input waveforms. The IC is also equipped with static protection and can tolerate up to 2000V of human body model static discharge, safeguarding it from the common electrostatic damages during handling and operation.

The CD4017B is available in various packages, including the popular DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit), providing flexibility for different types of PCB layouts and space requirements. Its low power consumption and wide operating temperature range (-55°C to +125°C) make it suitable for use in a wide array of environmental conditions.

Whether you're designing light sequencers, digital counters, or other creative digital projects, the CD4017B from Texas Instruments is a go-to component for a reliable and efficient performance.
