CD74HC4017 TI High Speed CMOS Decade Counter 10 Decoded Outputs DIP-16

Description

Product Overview

The CD74HC4017 is a high‑speed CMOS logic device designed to meet the demanding requirements of modern industrial and scientific applications. Built on Texas Instruments’ proven 74HC family, this decade counter provides ten fully decoded outputs that can be used directly in a wide variety of digital circuits. Its architecture features a five‑stage Johnson counter, positive‑edge clocking, and a common reset line, allowing for precise control of sequential operations. The device operates reliably up to 50 MHz when powered at 5 V, and its low power consumption makes it suitable for battery‑powered or energy‑constrained designs. The DIP‑16 package is optimized for breadboard and prototype environments, offering easy insertion and removal without the need for specialized tooling. With a temperature range spanning –55 °C to 125 °C, the CD74HC4017 can withstand harsh industrial conditions while maintaining consistent timing characteristics.

Usage

Engineers and designers frequently employ the CD74HC4017 in applications that require reliable counting, sequencing, or timing functions. Typical use cases include LED chasers, digital clocks, frequency division, and state‑machine implementations where a deterministic sequence of ten steps is required. The device’s ability to drive up to ten standard LSTTL loads per output, and even higher loads for bus driver configurations, ensures compatibility with a broad range of downstream components. In industrial automation, the counter can be integrated into motor control panels, sensor multiplexing circuits, and communication protocol handlers where precise event counting is essential. Its robust temperature tolerance also makes it a solid choice for outdoor equipment, aerospace instrumentation, and harsh‑environment monitoring stations. Because the CD74HC4017 supports a common reset input, multiple counters can be synchronized across a system, simplifying the design of complex timing networks.

FAQ

What is the maximum clock frequency for the CD74HC4017?

The device is rated for a typical maximum operating frequency of 50 MHz when supplied with a 5 V power rail and a load capacitance of 15 pF. Performance may vary slightly with temperature and load conditions, but the part is designed to meet this specification across its full operating range.

Can the CD74HC4017 be used with a common reset signal?

Yes, the counter includes a common reset input that, when asserted, forces all output stages to a known state. This feature allows multiple counters to be synchronized or individually reset, simplifying the design of coordinated timing systems.

How many standard LSTTL loads can each output drive?

Each standard output is capable of driving up to ten LSTTL loads, while the bus driver configuration can handle up to fifteen LSTTL loads. This flexibility ensures compatibility with a wide range of downstream logic families.

Is the CD74HC4017 suitable for low‑power applications?

Absolutely. The fully static operation means that the device consumes minimal power when the clock is idle, making it an excellent choice for battery‑operated or energy‑efficient designs that require reliable counting functionality.

What packaging options are available for this part?

The CD74HC4017 is offered in a 16‑pin DIP (dual‑in‑line package) that is breadboard‑friendly and ideal for prototyping. This package provides easy handling and soldering for both hobbyist and professional development environments.
