74HCT4017D,653

Counter Dividers Overview

The Nexperia 74HCT4017D,653 is a 5-stage Johnson decade counter with 10 decoded outputs (Q0 to Q9) and an output from the most significant flip-flop (Q5-9). It features two clock inputs (CP0 and CP1) and an overriding asynchronous master reset input (MR). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40 °C to +125 °C. It is housed in a 16-lead SO plastic small outline package (SOT109-1).

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 interface to voltages exceeding VCC using current limiting resistors.

Counter Dividers Applications

• Decade counter with decimal decoding
• Sequential controller
• Timer

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm the logic family designation corresponds to the intended TTL-compatible input levels. Ensure the component status remains active for long-term availability before finalizing design integration.

Counter Dividers Selection Notes

Select this part when CMOS low power dissipation and high noise immunity are required alongside TTL-level input compatibility. The asynchronous master reset allows immediate initialization independent of clock states. Verify that the operating frequency requirements align with the specified maximum frequency limits under the target load capacitance conditions.
