• Frequency division applications in communication systems
• Event counting modules in industrial control equipment

Counter Dividers Procurement Notes

Verify component authenticity through manufacturer documentation as this part may be obsolete. Confirm package integrity and pin alignment against the 16-SOIC specification before integration. Ensure supply chain sources provide traceable manufacturing records to guarantee operational reliability in critical designs.

Counter Dividers Selection Notes

Select this component when a synchronous four-bit counter with wide voltage tolerance is required. The AC series offers performance characteristics suitable for high-speed digital logic. Verify that the surface mount package aligns with the printed circuit board layout constraints and thermal management requirements of the target application.

Counter Dividers Part Context

This integrated circuit belongs to the CD74AC163 family, which includes variants such as the CD74AC163M. While the base model defines the core logical function, suffixes indicate specific packaging or environmental compliance variations. The E suffix typically denotes a specific package configuration distinct from other available form factors.
