Description

The Intersil HCS27MS is a Radiation Hardened Triple 3-

Input NOR Gate. A Low on all inputs forces the output to a

High state.

The HCS27MS 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 HCS27MS is supplied in a 14 lead Ceramic flatpack (K

suffix) or a SBDIP Package (D suffix).
