Description
The Intersil HCS20MS is a Radiation Hardened Dual 4-Input NAND Gate. A low on any input forces the output to a High state. The HCS20MS 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 HCS20MS is supplied in a 14 lead Ceramic flatpack (K suffix) or a SBDIP Package (D suffix).
