Rochester Electronics, a source for discontinued semiconductors for aerospace and defense applications, is expanding its inventory and manufacturing capabilities for space-qualified semiconductors that resist the effects of space radiation. Rochester is manufacturing radiation-hardened (rad-hard) devices for space electronics that meet guidelines of the MIL-PRF-38535 standard for integrated circuits manufacturing, administered by the U.S. Defense Electronics Center Columbus (DSCC) in Columbus, Ohio, and is a member of the DSCC Class V Qualified Manufacturing List (QML). Rochester is building 300 space-level logic devices acquired from National Semiconductor. Rochester also is authorized to manufacturer rad-hard processor technology, and will acquire and manufacture space-level linear products in the near future, company officials say. Rochester also provides discontinued rad-hard and other semiconductor products from National Semiconductor, Texas Instruments, Fairchild Semiconductor, and other chip manufacturers. The company also is developing rad-hard testing capabilities. For more information, visit Rochester Electronics online at www.rocelec.com.
