Texas Instruments Inc. has released a family of high-reliability power management ICs and advanced CMOS (AC) logic devices to increase system-level reliability in applications exposed to long-term radiation and extreme temperatures, such as downhole drilling, x-ray imaging, satellite systems and high-altitude avionics.

The new UC18xx PWM controllers for switching power supply-based applications, plus the new UC1525B-SP offer improved rate sensitivity, allowing for greater than 30 krad(Si) tolerance to low dose rate radiation. In addition, three new parts in TI's SN54ACxx AC logic family reach a total irradiated dose (TID) level of 50 krad(Si) to allow for lower leakage current and improved radiation performance.

The new UC18xx-SP devices, the UC1525B-SP and the new SN54ACxx-SP parts are now available.
