The Intersil HS-6617RH-T is a radiation hardened 16k CMOS PROM, organized in a 2K word by 8-bit format. The chip is manufactured using a radiation hardened CMOS process, and is designed to be functionally equivalent to the HM-6617. Synchronous circuit design techniques combine with CMOS processing to give this device high speed performance with very low power dissipation.
