Description

The Intersil HCS14MS is a Radiation Hardened HEX Invert-

ing Schmitt trigger. A high on any input forces the output to a

Low state.

The HCS14MS 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 HCS14MS is supplied in a 14 lead Ceramic flatpack

Package (K suffix) or a 14 lead SBDIP Package (D suffix).
