Flip Flops Procurement Notes

Verify component authenticity through authorized distribution channels due to the part's discontinued status. Confirm that the received unit matches the original STMicroelectronics marking and packaging specifications. Ensure compliance with environmental regulations such as RoHS3 before integration into final assemblies. Cross-reference datasheet parameters against design requirements to guarantee functional equivalence in legacy system replacements.

Flip Flops Selection Notes

Select this component for designs requiring octal storage with tri-state output control. Evaluate the 2V to 6V supply range compatibility with existing system power rails. Consider the 90 MHz clock limit and 32ns propagation delay for timing-critical paths. Assess the 20-SOIC footprint constraints against available PCB real estate. Verify thermal performance within the -55°C to 125°C operational envelope.
