MC14017BD

Counter Dividers Overview

The MC14017BD is a five-stage Johnson decade counter with a built-in code converter, manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18.0 Vdc and supports an ambient temperature range from -55°C to +125°C. The device features ten decoded outputs that transition high at specific decimal time periods triggered by the positive-going edge of the clock pulse. It includes dedicated pins for Clock Enable, Reset, and Carry Out, facilitating cascading and divide-by-N counting applications.

Counter Dividers Feature Summary

• Fully static operation allows for DC clock input circuits accommodating slow rise times.
• Carry out output pin enables seamless cascading for expanded decoding capabilities.
• Triple diode protection is integrated on all inputs to guard against high static voltages.
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load.

Counter Dividers Applications

• Frequency division circuits
• Decade counter logic designs
• Decimal decode display systems

Counter Dividers Procurement Notes

Verify the exact suffix designation during procurement, as ordering information distinguishes between standard SOIC-16 packaging (MC14017BD) and lead-free variants (MC14017BDR2G). Confirm package dimensions match the required footprint, specifically referencing Case 751B for the SOIC-16 configuration. Ensure environmental compliance requirements align with the specific revision and manufacturing site indicated in the datasheet documentation.

Counter Dividers Selection Notes

Select this component when a single-chip solution for sequential decoding is required without external logic gates. The wide supply voltage range makes it suitable for various digital environments. Consider the propagation delay characteristics relative to the system clock frequency. Verify that the load capacitance requirements are met to ensure signal integrity across the operating temperature range specified in the electrical characteristics table.

Counter Dividers Part Context

This part belongs to the MC14017B series of CMOS logic devices produced by onsemi. It serves as a direct pin-for-pin replacement for the industry-standard CD4017B. The family is characterized by robust noise immunity and low power consumption typical of CMOS technology. It is widely utilized in general-purpose digital timing and sequencing applications requiring reliable decade counting functionality.

Counter Dividers Replacement Considerations

The MC14017BD functions as a pin-compatible alternative to the CD4017B. Designers should verify that the replacement meets the specific voltage and current drive requirements of the target application before implementation.

Counter Dividers FAQ

How does the reset function affect the counter state?

Applying a high level to the Reset pin forces the counter to return to the Q0 state, regardless of the current count position or clock activity.

What determines the maximum operating speed of the device?

The maximum clock frequency depends on the supply voltage and load capacitance, with specifications provided in the switching characteristics section of the datasheet.
