Overview
The JM54AC245SSA-RH is a rad-hard octal bus transceiver designed for aerospace applications. It features 3-state outputs and operates within a voltage range of 2V to 6V for the CMOS series. The device ensures radiation hardness with a total ionizing dose (TID) tolerance of 300 krad(Si) and immunity to single event latch-up (SEL) up to 110 MeV.cm²/mg. It supports an extended temperature range from -55°C to +125°C and utilizes hermetic ceramic packaging.
Feature Summary
- Rad-hard design qualified for harsh space environments
- Octal bidirectional bus transceiver with 3-state outputs
- Immune to single event latch-up (SEL)
- Hermetic ceramic package construction
Applications
- Spacecraft data bus interfaces
- Satellite communication systems
- Harsh environment industrial control
Procurement Notes
Verify the specific suffix 'RH' against the manufacturer's current QML-V qualification list. Confirm that the hermetic ceramic package meets MIL-PRF-38535 requirements. Ensure the order includes necessary screening reports for TID and SEL performance as specified in the SMD documentation.
Selection Notes
Select this component when radiation hardness is critical. It serves as a direct replacement for standard 54AC245 devices in non-radiation environments only if hermeticity is not required. Verify voltage compatibility with the 2V to 6V operating range. Check pinout compatibility with existing PCB layouts.
Part Context
This part belongs to the 54AC/ACT series of high-speed CMOS functions. These components are specifically engineered to meet stringent radiation requirements for the aerospace industry. The series includes various logic gates, flip-flops, and bus interfaces suitable for demanding environmental conditions.
Replacement Considerations
Standard commercial 54AC245 parts lack radiation hardness and hermetic sealing. Do not substitute with non-QML-V qualified equivalents without verifying radiation tolerance. Check for equivalent Rad-Hard parts from other manufacturers if availability is limited.
