Description
The Intersil HCTS74MS is a Radiation Hardened positive
edge triggered flip-flop with set and reset.
The HCTS74MS 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 HCTS74MS is supplied in a 14 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
