M38510/50604BRA

Product Overview

The M38510/50604BRA is a controlled military or source-control identifier associated with Texas Instruments programmable logic. The drawing number—not a guessed commercial cross-reference—is the controlling device identity for logic organization, screening, case outline and electrical limits.

Architecture and Logic Role

The exact programmed architecture and electrical behavior are defined by the applicable military drawing and loaded fuse pattern. Similar numbering within a drawing family does not prove identical pinout, output organization or timing.

Device-Specific Identification

• Controlled identifier: resolve using the governing military/source-control drawing
• Commercial equivalent and exact screening level: not asserted without drawing evidence

Design and Replacement Considerations

Before substitution, compare the complete ordering suffix, pinout, supply and input thresholds, output drive, propagation delay, clock/reset behavior, power-up state and programmer support. Low-power Q, Z and QZ versions are not interchangeable assumptions: standby entry and active-current behavior differ. Military drawing numbers require the applicable slash sheet and screening documentation.

Typical Applications

• Military and aerospace legacy-board maintenance
• Configuration-matched logic replacement
• Address decode and deterministic control logic
• Depot repair using controlled drawings and programming data

Quality and Sourcing

For M38510/50604BRA, verify full top and underside markings, manufacturer traceability, date code, case condition, lead finish and programming status. Establish whether blank or preprogrammed material is needed and retain the correct JEDEC file. For older or military stock, request storage, solderability and compliance evidence and screen for remarking or erased-window handling issues where applicable.
