Radiation Tolerant 8-Channel Source Driver with Internal Thermal Shutdown The AAHS298B is part of AAIs new family of Radiation Tolerant products, aimed at the military and aerospace markets. The AAHS298A is a Radiation-Tolerant source driver with eight non-inverting channels, with internal thermal shutdown. Capable of providing interface from 5V or 12V logic systems to relays, motors, solenoids and other loads, this device adds the additional benefits of an internal thermal shutdown and output transient protection/clamp diodes with sustaining voltages to 80V. Each output is capable of sourcing 750mA with a withstand voltage of 80V over the full military temperature range. The Thermal Shutdown is intended to protect against over-current and soft short occurrences. The AAHS298B comes in die form, 24-Pin Ceramic SOIC or 20-Pin Ceramic SOIC. The AAHS298B has demonstrated tolerance to 200kRad(Si) total dose, as well as immunity to latch-up and SEE tolerance. Available standard screening includes Level “S” or Level “B,” with other requirements negotiable as in line with our capabilities. Features 
(1) Add “-S” or “-B” to end of part number to specify class S or B screening levels. Die is only offered with class S screening, as indicated. Contact factory for ENGR samples.
