Overview

Support is limited to customers who have already adopted these products.

The Intersil HCTS85MS is a Radiation Hardened 4-bit high speed magnitude comparator. This device compares two binary, BCD, or other monotonic codes and presents the three possible magnitude results at the outputs (A>B, A<B, and A=B). The 4-bit input words are weighted (A0 to A3 and B0 to B3), where A3 and B3 are the most significant bits. The HCTS85MS is expandable without external gating, both serial and parallel operation. The HCTS85MS utilizes advanced CMOS/SOS technology to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family with TTL input compatibility. The HCTS85MS is supplied in a 16 lead Ceramic flatpack (K suffix) or a SBDIP Package (D suffix).
