74HC4017D,652

Counter Dividers Overview

The Nexperia 74HC4017D,652 is a 5-stage Johnson decade counter featuring 10 decoded outputs (Q0 to Q9), an output from the most significant flip-flop (Q5-9), two clock inputs (CP0 and CP1), and an overriding asynchronous master reset input (MR). It operates within a supply voltage range of 2.0 V to 6.0 V. The device advances on LOW-to-HIGH transitions at CP0 while CP1 is LOW, or HIGH-to-LOW transitions at CP1 while CP0 is HIGH. It includes automatic code correction returning to proper mode within 11 clock pulses following illegal codes.

Counter Dividers Feature Summary

• Features dual clock inputs for flexible counting control via edge-triggered transitions
• Includes an internal circuit for automatic code correction after illegal states
• Provides inputs with clamp diodes enabling interface to voltages exceeding VCC using current limiting resistors

Counter Dividers Applications

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