Description

The Intersil HCTS20MS is a Radiation Hardened Dual 4-Input

NAND Gate. A low on any input forces the output to a High state.

The HCTS20MS utilizes advanced CMOS/SOS technology to

achieve high-speed operation. This device is a member of radia-

tion hardened, high-speed, CMOS/SOS Logic Family.

The HCTS20MS is supplied in a 14 lead Ceramic flatpack

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