SN54SC245MPWTSEP

Buffers, Drivers, Receivers, Transceivers Overview

The SN54SC245MPWTSEP is a radiation-tolerant, octal bus transceiver with 3-state outputs designed for space applications. It operates within a supply voltage range of 1.2 V to 5.5 V and supports an operating temperature from -55°C to 125°C. The device features 5.5 V tolerant input pins and provides output drive up to 25 mA at 5 V. Total ionizing dose is characterized at 30 krad(Si), and it is immune to single-event latch-up at linear energy transfer levels up to 43 MeV-cm²/mg.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Radiation tolerance including total ionizing dose characterization and single-event effects immunity
• Wide operating voltage range supporting low-power and standard logic interfaces
• Space enhanced plastic construction with gold bondwires and controlled baseline manufacturing

Buffers, Drivers, Receivers, Transceivers Applications

• Enable or disable digital signals in harsh environments
• Eliminate slow or noisy input signals
• Hold a signal during controller reset
• Debounce a switch

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix MPWTSEP against the manufacturer's current datasheet to confirm package type and material specifications. Ensure the vendor item drawing VID V62/23616 matches project requirements. Confirm that the radiation lot acceptance testing (TID RLAT) documentation is available for quality assurance purposes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when radiation hardness is required for space missions. It is suitable for interfacing between different voltage domains due to its wide supply range. Verify that the thermal resistance and power dissipation capabilities meet the system's heat management constraints under maximum load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54SC245-SEP family, which is specifically engineered for military and aerospace use. It shares functional similarities with standard commercial octal bus transceivers but includes enhanced reliability features such as one assembly site, one fabrication site, and product traceability to meet NASA ASTM E595 outgassing specifications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must be verified against the Vendor Item Drawing (VID). Standard commercial SC245 variants lack the necessary radiation tolerance and SEP packaging. Consult the manufacturer's obsolescence notices for alternative qualified parts if this specific suffix is discontinued.
