SN74LS163AMR1 is listed in the Counter Dividers range at ChipApex. The manufacturer field lists Motorola. Its product description is IC BCD COUNTER 4-BIT 16SOEIAJ. Review the specifications below when checking this part for your BOM.
The SN74LS163AMR1 is a synchronous 4-bit binary counter belonging to the Motorola 74LS series. It features positive edge triggering and counts in an up direction. The device includes a synchronous clear function, allowing the output to be reset without affecting the clock signal. It is housed in a 16-pin plastic dual small outline package (PDSO16). This component operates within standard TTL logic voltage ranges and is designed for reliable digital counting applications.
Verify the obsolete status of this Motorola part before procurement planning. Confirm that the PDSO16 package matches your PCB footprint requirements. Ensure compatibility with existing 74LS logic levels in your design. Check for lead-free compliance if required by your manufacturing standards. Source from authorized distributors to guarantee authenticity.
Select this component when a synchronous 4-bit binary counter is required within a 74LS logic environment. It is suitable for designs needing precise clock-edge synchronization. Consider the PDSO16 package size for space-constrained layouts. Verify that the synchronous clear feature aligns with your system reset strategy. Ensure power supply constraints match standard TTL operation.
This part belongs to the broader 74LS163 family of synchronous counters. It shares functional similarities with other LS-series devices but is specific to Motorola's manufacturing lineage. The 'A' suffix typically denotes a specific variant or revision within the product line. It is distinct from asynchronous counters like the 74LS161 due to its synchronous control inputs.
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Motorola or ON Semiconductor catalogs for current equivalents. Cross-referencing with generic 74LS163 datasheets may identify compatible alternatives from other manufacturers.
