Product Overview: NXP HEF4017BP Decade Counter/Divider

The NXP HEF4017BP is a high-performance, integrated circuit that functions as a decade counter/divider. It is a versatile component that finds applications in various electronic projects, including timing circuits, counters, and sequential control systems. The HEF4017BP is part of the HEF4000 family, which is renowned for its robustness and reliability.

Key Features

• Counter Type: 5-stage Johnson decade counter with 10 decoded outputs.
• Supply Voltage Range: The device operates over a wide voltage range from 3V to 15V, making it suitable for battery-operated devices as well as industrial applications.
• High-Speed Operation: It is capable of high-speed operation, which makes it an excellent choice for high-frequency counting applications.
• Output Capability: Standard outputs are capable of driving 10 LSTTL loads, which means it can directly interface with low-power Schottky TTL (LSTTL) logic without additional buffering.
• Temperature Range: The device can operate over a broad temperature range, ensuring reliability in varying environmental conditions.
• Package: The HEF4017BP is available in a 16-pin DIP (Dual In-line Package), which is easy to handle and suitable for breadboard prototyping or PCB mounting.

Functional Description

The HEF4017BP is designed with an internal arrangement of flip-flops that provide decoded decimal (base-10) count outputs. Each time the input count pulse is received, the counter advances by one, and the corresponding output pin goes high while the others remain low. This sequential high output can be used to drive other circuits or components in a controlled manner. An additional feature of this IC is the reset function, which allows the counter to be set back to zero at any time, thus providing flexibility in control applications.

Applications

This component is widely used in LED chasers, frequency dividers, clocks, timers, and sequence controllers. Its ability to interface with other digital logic families and its easy-to-use pin configuration make it a favorite among hobbyists and professionals alike. Whether you are designing an interactive art installation or developing a sophisticated industrial control system, the NXP HEF4017BP offers a reliable and efficient solution for your counting and dividing needs.
