Description
The Intersil HCTS244MS is a Radiation Hardened Non-
Inverting Octal Buffer/Line Driver, Three-State, with two
active-low output enables.
The HCTS244MS 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 HCTS244MS is supplied in a 20 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
