JM54AC245SRA-RH

Overview

The JM54AC245SRA-RH is a radiation-hardened octal bus transceiver manufactured by National Semiconductor. It utilizes advanced high-speed CMOS technology and features three-state outputs for direct bus line driving. The device operates within a voltage range of 2 V to 6 V and supports a temperature range from -55 °C to +125 °C. It provides total ionizing dose (TID) hardness up to 300 krad (Si) and is immune to single event latch-up (SEL) up to 110 MeV.cm²/mg. The component is housed in a hermetic package suitable for aerospace applications.

Feature Summary

• Radiation hardened design with immunity to single event latch-up and upset
• Hermetic packaging compliant with MIL-PRF-38535 standards
• High-speed CMOS technology ensuring low power consumption

Applications

• Aerospace systems requiring radiation tolerance
