Product Overview: Texas Instruments CD54HC4017F3A

The Texas Instruments CD54HC4017F3A is a high-speed CMOS Logic Decade Counter/Divider integrated circuit that is part of the HC and HCT series. This precision-engineered component is designed for use in a wide range of electronic applications, from simple counting operations to more complex sequential logic tasks.

The CD54HC4017F3A features a 5-stage Johnson decade counter with ten decoded outputs, which are especially useful for driving lamps or LEDs, as well as for generating timing sequences. Each of the decoded outputs is normally low and sequentially goes high on the low-to-high transition of the clock input. Moreover, an additional output is provided as a carry-out signal for cascading multiple CD54HC4017F3A devices, enabling the creation of counters with longer sequences or different counting modes.

The device is characterized by its high noise immunity and low power consumption, which is typical of CMOS integrated circuits. It operates over a broad voltage range from 2V to 6V, making it versatile for both battery-powered and traditional powered applications. The CD54HC4017F3A also features a master reset input that immediately resets the counter to its zero state when activated.

Key specifications of the CD54HC4017F3A include:

• Decade counter with 10 decoded outputs
• High current sourcing capability for directly driving LEDs
• Standardized, symmetrical output characteristics
• High noise immunity characteristic of CMOS devices
• Multiple package options for design flexibility

For designers and engineers, the CD54HC4017F3A offers a reliable and robust solution for applications requiring counting or divide-by functions. Its compatibility with other logic families, thanks to its standardized output characteristics, makes it an excellent choice for mixed-technology systems. Whether used in consumer electronics, automotive, or industrial applications, the CD54HC4017F3A from Texas Instruments is a dependable component that ensures precise and stable operation.
