The AAHS298B is a Radiation-Tolerant source driver with eight non-inverting channels, with internal thermal shutdown. Capable of providing an interface from TTL, 5V or 12V logic systems to relays, motors, solenoids, and other loads, this device adds the additional benefit of an internal thermal shutdown and output transient protection/clamp diodes with sustaining voltages to 75V. Each output is capable of sourcing 700mA with a withstand voltage of 75V over the full military temperature range. The thermal shutdown is intended to protect against over-current and soft-start occurrences. The AAHS298B is offered in a 20-pin ceramic SOIC. The AAHS298B has demonstrated tolerance to 100kRad (Si) total dose, as well as immunity to latch-up and SEE tolerance. Available standard screeni...
