The Intersil HCS32MS is a Radiation Hardened Quad 2-Input OR Gate. A low on both inputs forces the output to a low state.
The HCS32MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of the radiation hardened, high-speed, CMOS/SOS Logic Family.
The HCS32MS is supplied in a 14 Ld Ceramic flatpack (K suffix) or a SBDIP Package (D suffix).
