Overview
The MC14585BCP is a 4-bit magnitude comparator produced by onsemi. This device is constructed with complementary MOS (CMOS) enhancement mode devices and is designed to compare two 4-bit binary numbers, determining whether the first number is less than, equal to, or greater than the second number. It features eight comparing inputs (A3, B3, A2, B2, A1, B1, A0, B0) and three outputs (A < B, A = B, and A > B), along with three cascading inputs to enable the comparison of words greater than 4 bits by cascading multiple units.
