Key Features
- Full MIL-STD-1553B and MIL-STD-1760 dual-redundant avionics bus protocol support at 1 Mbit/s for military system integration
- 8-bit parallel host interface in a 40-pin DIP package enabling direct connection to legacy embedded processors without FPGAs
- Bus controller, remote terminal, and bus monitor triple-mode operation in a single IC for flexible avionics network roles
Applications
TMS9650NL is used in military aircraft and naval vessel avionics systems requiring MIL-STD-1553B dual-redundant databus connectivity at 1 Mbit/s. Defense system integrators rely on it for weapon store management and flight control data links conforming to MIL-STD-1760. Its 40-pin DIP form factor simplifies board-level replacement in legacy avionics maintenance programs where through-hole construction is mandated by service specifications.

Frequently Asked Questions
Which avionics bus protocols does TMS9650NL implement, and at what data rate?
TMS9650NL implements both MIL-STD-1553B and MIL-STD-1760 protocols at the standard 1 Mbit/s serial bus rate, supporting all three node types — bus controller, remote terminal, and bus monitor — on a dual-redundant 2-wire differential bus topology.
How does the 8-bit host interface on TMS9650NL connect to a legacy 8-bit microprocessor in an existing avionics chassis?
TMS9650NL provides a parallel 8-bit data bus and dedicated address/control lines that map directly onto Intel 8085 or Motorola 6800 style bus cycles, allowing it to be socket-mounted in a 40-pin DIP slot without additional logic glue in chassis designs built to original 1553 interface specifications.
When maintaining a legacy defense radar system, how critical is sourcing original TMS9650NL versus a modern ASIC replacement?
For FAA- or DoD-certified avionics where re-qualification costs can exceed $500,000 per part substitution, using the original TMS9650NL in a 40-pin DIP package avoids redesign and re-certification cycles, making original-component sourcing from distributor stock a cost-effective MRO strategy.
What package does TMS9650NL use, and does that affect thermal management in an enclosed avionics bay?
TMS9650NL ships in a through-hole 40-pin DIP package with a 0.6-inch row spacing, dissipating heat through its plastic epoxy body and lead frame; in sealed avionics bays with limited convective cooling, ensuring at least 50 mW/°C of conducted path to the chassis keeps junction temperature within rated limits.
