Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact pin count and carrier type. Ensure procurement channels are authorized for QML certified components. Confirm that the RoHS exemption aligns with project requirements, as this part is designated as non-compliant.

Selection Notes

Select this component when operating temperatures exceed standard commercial limits or when military qualification is mandatory. Compare against the SNJ54LS139AJ for identical logic functions in alternative ceramic packages. Verify that the 20-pin LCCC footprint matches the target PCB layout constraints.

Part Context

This part belongs to the SN54LS139A family, which includes catalog, military, and space-qualified versions. It serves as a digital logic interface for converting binary inputs into one-of-N outputs. The M38510 designation indicates compliance with MIL-M-38510 specifications for microcircuits.
