Description
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).
