Specialty Logic Procurement Notes

Verify the specific suffix 'JT' indicates the ceramic dual in-line package configuration and lead-free status if required. Confirm that the component meets military-grade specifications for the intended application environment. Ensure compatibility with existing PCB footprints designed for 24-lead CDIP packages. Check for any specific handling requirements associated with ceramic packaging during assembly.

Specialty Logic Selection Notes

Select this component when scan test accessibility is required alongside standard bus transceiver functionality. It is suitable for applications demanding operation across the full military temperature range. Consider the through-hole mounting requirement inherent to the CDIP package. Evaluate system speed requirements against the propagation delay characteristics of the BCT series.
