SN74HC163DR from Texas Instruments is a logic counter device in the Counters, Dividers category, commonly used in digital timing, event counting, frequency division, sequencing, and control logic designs. Engineers typically consider parts in this family for embedded systems, industrial controllers, test equipment, and consumer electronics where predictable digital counting functions are required. Texas Instruments is widely recognized for stable logic portfolios, which can make this part relevant for both new evaluations and maintenance of existing designs. The current lifecycle status for SN74HC163DR is information not available, so design teams should confirm product status directly with Texas Instruments or authorized channel partners before committing to long-term production. RoHS compliance information is also not available in the provided data and should be verified against the latest manufacturer documentation. For procurement, this part is best treated as a component requiring current availability, compliance, and documentation checks before design-in or volume purchasing decisions.
