Description

The Intersil HCTS93MS is a Radiation Hardened 4-bit binary ripple counter consisting of four master-slave flip-flops internally connected to provide a divide-by-two and a divide-by-eight section. Each section has a separate clock input.

The HCTS93MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family.
