Description
The Intersil ACS521MS is a Radiation Hardened 8 bit magnitude comparator device. It provides a low output YB when Word A equals word B and input GB is low. All other input states cause a high output.
The ACS521MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family.
The ACS521MS is supplied in a 20 lead Ceramic Flatpack (K suffix) or a Ceramic Dual-In-Line Package (D suffix).
