Counter Dividers Procurement Notes

Verify the specific suffix B2A matches the required lead finish and case outline for your assembly process. Confirm that the MIL-M-38510/32702 specification requirements align with your procurement contract. Ensure the supplier provides traceability documentation compliant with MIL-PRF-38535 standards for this microcircuit class.

Counter Dividers Selection Notes

Select this component when dual 4-bit binary counting is required in harsh environments. It is suitable for applications demanding high radiation tolerance and wide temperature stability. Compare against other LS TTL series parts if lower power consumption or different pin counts are needed. Verify compatibility with existing TTL logic families in the design.

Counter Dividers Part Context

This part belongs to the Texas Instruments JM38510 family of military microcircuits. It adheres to MIL-M-38510 specifications for low-power Schottky TTL counters. The device is classified as active production data, indicating ongoing manufacturing support. It serves as a specialized replacement for legacy military digital logic designs requiring robust performance.

Counter Dividers Replacement Considerations

Check for direct cross-references from Lansdale M38510/31502B2A. Verify pinout compatibility before substitution. Ensure the replacement meets the same MIL-M-38510/32702 electrical and mechanical specifications.
