DESCRIPTION
The Intersil 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.
