Description

The Intersil HCS21MS is a Radiation Hardened Dual Input

AND Gate. A high on all inputs forces the output to a High

state.

The HCS21MS 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 HCS21MS is supplied in a 14 lead Ceramic flatpack (K

suffix) or a SBDIP Package (D suffix).
