Description
The Intersil HCTS646MS is a Radiation Hardened Three-
State Octal Bus Tranceiver/Register with Non-Inverting
outputs. This device is a bus transceiver with D-type flip-flops

The HCTS646MS 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 HCTS646MS is supplied in a 24 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
