Description
The Intersil HCS02MS is a Radiation Hardened Quad 2-
Input NOR Gate. A low on both inputs forces the output to a
High state.
The HCS02MS 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 HCS02MS is supplied in a 14 lead Ceramic Flatpack
Package (K suffix) or a 14 lead SBDIP Package (D suffix).
