74HC85 4-bit Magnitude Comparator IC – DIP-16 Package
The ’HC85 and ’HCT85 are high speed magnitude comparators that use silicon-gate CMOS technology to achieve operating speeds similar to LSTTL with the low power consumption of standard CMOS integrated circuits. These 4-bit devices compare two binary, BCD, or other monotonic codes and present 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. This product is known as 4 bit Magnitude Comparator IC, 7485, 74HC85, 74HC85 4 bit Magnitude Comparator IC, 74XXX series IC, CD74HC85E, CD74HC85NSR, 74HC85D, CD74HC85EE4, CD74HC85PW, CD74HC85M.
