The CD74HC4017NSR is part of the CD74HC4000 Series logic family, providing high speed CMOS logic. Generally integrated into logic-based applications such as counters, dividers, and clocks, the CD74HC4017NSR is available as a 16-pin dual in-line plastic or small/low-outline (SO/SOP) and flatpack package. Specifics of its performance and capabilities will be discussed in this article, including some real-life uses, applications fields, working principles and features.

The CD74HC4017NSR- is distinctive for its high-speed operation capability as well as having an excellent power-supply noise immunity. In comparison to the CD74HC4017NS it has improved operating range and ESD (Electrostatic Discharge) protection at up to 2000V. Other advantages compared to the CD74HC4017NS include a higher speed clock operation and improved noise margin.

Real life applications may include clocks that use binary or BCD signals, rechargeable batteries or any other type of remote control circuit, which can be used as an input to a PLC or gate array. The CD74HC4017NSR can also be used in a variety of applications such as counter, decoder, and digital logic circuits. It can also be used in a sequencer for complex logic, delay line for analog filtering, and multiplexing. The device is suitable for use in industrial, automotive and portable applications.

The main application fields for the CD74HC4017NSR are logic-based applications such as clocks, dividers, and counters. As a clock, the device can be used to alternate between two devices at a given frequency depending on the input signal. As a divider, it can divide an input signal into two signals, with the first being one half of the original frequency. When used as a counter, it can be used to count up to 8 pulses, powering the output “on” and “off” when the right count is reached.

The working principle behind the CD74HC4017NSR is fairly simple. When given an input signal, the device sequences it and outputs a logic 1 when the count reaches 8. The count value is reset when the reset (R1) input is asserted. The count enable (CE) input is used to enable or disable the count sequence; when it is high, the counter is enabled and when low, it is disabled. The clock (CP) input provides the clock pulses. All other inputs are held low. Based on these parameters, the counter can be made to count up (normal operation) or down (reverse operation) depending on the logic of the inputs.

The features of the CD74HC4017NSR include a low-power CMOS logic with low power consumption and short propagation delay times. In addition, it has a wide range of operating temperatures from -40°C to 125°C, making it suitable for a variety of environments. The device is also ESD protected up to 2000V and is available in various packages, including the 16-pin SO/SOP or the 16-pin Flatpack.

The CD74HC4017NSR is an ideal device for logic-based applications such as counters, dividers and clocks. It provides an extremely high switching speed in comparison to previous logic devices. Additionally, due to its wide range of operating temperatures, ESD protection, and various packages it is widely used in industrial, automotive and portable applications.
