Procurement Notes
Verify product status carefully as this component is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure that the 24-DIP through-hole package specification matches the target PCB design constraints. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs before procurement.
Selection Notes
Select this component when a 16-channel constant current sink driver with shift register input is required for low-voltage LED applications. The 24-DIP package is suitable for through-hole assembly processes. Consider the 30MHz frequency limit and 80mA continuous current rating when designing the drive circuitry. Verify thermal management requirements given the DIP package's thermal characteristics.
Part Context
This part belongs to the STP16CPS05 series from STMicroelectronics, which focuses on low-voltage LED driving solutions. The series typically includes variants with different packaging options such as SOIC or TSSOP, but the B1R suffix specifically denotes the 24-DIP through-hole configuration. These drivers are engineered for cost-effective LED matrix applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official STMicroelectronics resources for potential obsolescence alternatives.
