74HC4017D,653

Counter Dividers Overview

The Nexperia 74HC4017D,653 is a 5-stage Johnson decade counter featuring 10 decoded outputs (Q0 to Q9) and an output from the most significant flip-flop (Q5-9). It includes two clock inputs (CP0 and CP1) and an overriding asynchronous master reset input (MR). The device operates on a wide supply voltage range of 2.0 V to 6.0 V with CMOS low power dissipation. It utilizes a 16-lead SO plastic small outline package (SOT109-1) and supports an operating temperature range from -40 °C to +125 °C.

Counter Dividers Feature Summary

• Features dual clock inputs allowing advancement via LOW-to-HIGH transitions at CP0 or HIGH-to-LOW transitions at CP1.
• Includes automatic code correction circuitry that returns the counter to a proper counting mode within 11 clock pulses following any illegal code.
• Inputs include clamp diodes enabling current limiting resistors for interfacing inputs to voltages in excess of VCC.

Counter Dividers Applications

• Decade counter with decimal decoding
• 1 out of n decoding counter when cascaded
• Sequential controller
• Timer

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm the logic family variant corresponds to the intended voltage levels, as HC and HCT versions differ in input compatibility. Ensure compliance with JEDEC standards relevant to the application environment. Check for recent product change notices regarding marking or assembly updates.

Counter Dividers Selection Notes

Select this component for applications requiring a single-chip decade counter with decoded outputs. The 74HC4017 variant provides CMOS input levels suitable for general digital logic interfacing. Consider the Q5-9 carry output for cascading multiple counters to extend the number of decoded states without dead time between stages.

Counter Dividers Part Context

This part belongs to the 74HC(HCT)4017 series of Johnson decade counters manufactured by Nexperia USA Inc. The 'D' designation indicates the SO16 plastic small outline package (SOT109-1), while the ',653' suffix typically denotes tape and reel packaging. It is part of a broader family including TSSOP and DHVQFN package options.
