Description
The Intersil HCS163MS is a Radiation Hardened synchronous
presettable binary counter that features lookahead carry logic for
use in high speed counting applications. Counting and parallel
load, and presetting are all accomplished synchronously with the
positive transition of the clock.
The HCS163MS 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 HCS163MS is supplied in a 16 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
