74HCT4017N,652

Counter Dividers Overview

The 74HCT4017N,652 is a 5-stage Johnson decade counter with 10 decoded active HIGH outputs (Q0 to Q9) and an active LOW carry output (Q5-9). It features dual clock inputs (CP0 for LOW-to-HIGH transitions, CP1 for HIGH-to-LOW transitions) and an overriding asynchronous master reset input (MR). The device operates on a supply voltage range of 4.5 V to 5.5 V, supports an operating temperature from -40 °C to +125 °C, and utilizes TTL-level inputs.

Counter Dividers Feature Summary

• Features dual clock inputs allowing count advancement via either positive or negative edge transitions
• Includes automatic code correction circuitry that restores proper counting mode within 11 clock pulses following illegal codes
• Provides an active LOW carry output suitable for cascading multiple counters

Counter Dividers Applications

• Decade counter with decimal decoding
• Sequential controller
• Timer
• Divide-by 2 through divide-by 10 circuits

Counter Dividers Procurement Notes

Verify the specific suffix 'N,652' corresponds to the PDIP-16 package variant. Confirm the manufacturer origin as Nexperia, which succeeded NXP's Standard Product business in February 2017. Ensure the datasheet revision matches current specifications before finalizing procurement.

Counter Dividers Selection Notes

Select this component when TTL-compatible logic levels are required at the inputs while maintaining CMOS performance characteristics. The HCT series ensures compatibility with standard 5V logic systems. Verify that the DIP-16 through-hole package meets the mechanical constraints of the target printed circuit board design.

Counter Dividers Part Context

This part belongs to the 74HCT4017 family of high-speed Si-gate CMOS devices. It is pin compatible with legacy HEF4017 designs but offers improved switching speeds and lower power dissipation. The product line includes various package options including SO, TSSOP, and DHVQFN variants alongside the standard DIP format.

Counter Dividers Replacement Considerations

The 74HC4017D,652 serves as a parameter-equivalent alternative within the same family, differing primarily in input voltage threshold requirements.
