74HC4017BQ,115

Counter Dividers Overview

The Nexperia 74HC4017BQ,115 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 asynchronous master reset input (MR). It operates within a supply voltage range of 2.0 V to 6.0 V. The device utilizes CMOS technology for low power dissipation and high noise immunity. It is housed in a DHVQFN16 package (SOT763-1) with dimensions of 2.5 x 3.5 x 0.85 mm. The maximum operating frequency reaches 83 MHz at 6.0 V.

Counter Dividers Feature Summary

• Features dual clock inputs allowing advancement via LOW-to-HIGH transitions on CP0 or HIGH-to-LOW transitions on CP1.
• Includes automatic code correction circuitry that returns the counter to a proper counting mode following any illegal code within 11 clock pulses.
• Inputs are equipped with clamp diodes, enabling interface to voltages exceeding VCC using current limiting resistors.

Counter Dividers Applications

• Decade counters with decimal decoding
• Sequential controllers
• Timers

Counter Dividers Selection Notes

Select this component when a 5-stage Johnson counter with decoded outputs is required in a leadless package. Ensure the design supports the 2.0 V to 6.0 V supply range and utilizes the DHVQFN16 footprint. Consider the 83 MHz maximum frequency capability for timing requirements.

Counter Dividers Part Context

This part belongs to the 74HC/HCT logic family, specifically the 74HC4017 series. It is a CMOS version of the standard decade counter. The BQ suffix indicates the DHVQFN16 package variant. It shares functional compatibility with other 74HC4017 packages like SO16 and TSSOP16 but differs in physical form factor and thermal characteristics.

Counter Dividers Replacement Considerations

Direct substitutes include other 74HC4017 variants in different packages such as 74HC4017D (SO16) or 74HC4017PW (TSSOP16). For TTL-compatible inputs, the 74HCT4017BQ,115 is functionally similar but requires a 4.5 V to 5.5 V supply.
