74HC4017DB,112

Counter Dividers Overview

The 74HC4017DB,112 is a high-speed Si-gate CMOS 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 on a supply voltage range of 2.0 V to 6.0 V and is housed in a SO16 plastic small outline package (SOT109-1). It complies with JEDEC standards JESD8C and JESD7A.

Counter Dividers Feature Summary

• Features dual clock inputs allowing advancement via LOW-to-HIGH transition at CP0 or HIGH-to-LOW transition at CP1.
• Includes automatic code correction circuitry that returns the counter to a proper counting mode within 11 clock pulses following any illegal code.
• Provides ESD protection exceeding 2000 V for Human Body Model and 1000 V for Charged Device Model.
• Inputs include clamp diodes enabling interface to voltages in excess of 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 '112' against the manufacturer's official documentation to confirm the exact packaging configuration. Confirm the active status of the component as datasheet revisions may indicate obsolescence or discontinuation notices. Ensure the required temperature range aligns with the specified -40 °C to +125 °C operating conditions.

Counter Dividers Selection Notes

Select this component when a 5-stage Johnson decade counter with decoded outputs is required. Verify compatibility with the system's logic levels, as the HC variant utilizes CMOS input levels. Consider the SO16 package dimensions if board space is constrained. Ensure the application does not exceed the latch-up performance limits defined by JESD 78 Class II Level B.

Counter Dividers Part Context

This part belongs to the 74HC/HCT4017 family of Johnson decade counters manufactured by Nexperia. It is pin-compatible with the legacy HEF4017 series. The 'DB' designation indicates the SO16 package type, while the '112' suffix typically denotes the specific tape and reel or tube packaging format provided by the distributor.

Counter Dividers Replacement Considerations

The 74HCT4017 serves as a functional replacement with TTL-level inputs. Other package variants such as 74HC4017PW (TSSOP16) or 74HC4017BQ (DHVQFN16) offer alternative form factors with identical electrical characteristics.
