MCH4017-TL-H

Overview

The MCH4017-TL-H is a CMOS decade counter and divider featuring ten decoded outputs, manufactured by onsemi. It operates as a Johnson-type counter with asynchronous reset capability and ripple clock inputs. The device supports wide supply voltage ranges typical of the 4000B series, enabling compatibility with various logic families. It includes dedicated carry-out terminals for cascading multiple stages to form longer counters or dividers. The component is housed in a compact surface-mount package suitable for space-constrained printed circuit board designs.

Feature Summary

• Provides ten mutually exclusive decoded outputs representing decimal digits zero through nine
• Supports cascading configurations via dedicated carry-in and carry-out terminals
• Features an asynchronous reset input for immediate initialization of the count sequence

Applications

• Digital timing sequences and pulse distribution circuits
• LED chaser lights and visual display drivers
• Frequency division and counting modules in digital systems

Procurement Notes

Verify the specific manufacturer suffix and tape-and-reel specifications against the official datasheet before ordering. Confirm that the requested variant matches the required operating temperature range and packaging format for your assembly process. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a single-chip solution for decimal counting or frequency division is required. Ensure the system voltage aligns with the standard CMOS operating range. Consider the package dimensions and pinout compatibility during PCB layout planning to maintain signal integrity and proper thermal management.

Part Context

This part belongs to the widely used 4000-series CMOS logic family, known for high noise immunity and low power consumption. It serves as a fundamental building block for sequential logic applications. The MCH4017 variant specifically offers the standard decade counting functionality within a modern surface-mount footprint, replacing older through-hole equivalents in contemporary electronics.

Replacement Considerations

Compatible substitutes include CD4017, HEF4017, and MC14017 from other manufacturers. Verify pin compatibility and electrical characteristics such as propagation delay and supply current before substitution.
