M74HC4017B1R

Counter Dividers Overview

The M74HC4017B1R is a high-speed CMOS decade counter/divider fabricated with silicon gate C2MOS technology. It functions as a 5-stage Johnson counter featuring ten decoded outputs that sequentially activate on the low-to-high transition of the clock input. The device includes a carry output for cascading, a clock enable input to disable counting, and an active-high master reset input. It operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of up to 48 MHz at 6V.

Counter Dividers Feature Summary

• Sequentially activates one of ten decoded outputs per clock cycle
• Includes dedicated carry output for multi-stage cascading
• Features active-low clock enable and active-high master reset inputs

Counter Dividers Applications

• Digital sequencing circuits
• Decoded display drivers
• Frequency division applications

Counter Dividers Procurement Notes

Verify the specific package type against the ordering code suffix. The B1R suffix indicates a Plastic DIP-16 (PDIP) package. Confirm that the required operating temperature range aligns with the -55°C to +125°C specification provided in the datasheet before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a synchronous decade counter with decoded outputs is required. Ensure the design utilizes a supply voltage between 2V and 6V. Verify that the logic family compatibility matches the system requirements, specifically noting the noise immunity and power dissipation characteristics defined for the HC series.

Counter Dividers Part Context

This part belongs to the M74HC4017 series of high-speed CMOS logic devices manufactured by STMicroelectronics. It is functionally compatible with the standard 74 Series 4017 but offers improved speed and lower power consumption due to its silicon gate C2MOS fabrication process. The device is designed for general-purpose digital counting and timing applications.

Counter Dividers Replacement Considerations

Compatible substitutes include other manufacturers' versions of the 74HC4017 in a DIP-16 package, such as the CD74HC4017E or MC74HC4017DDS, provided pinout and electrical specifications are verified.
