74HC85 4-Bit Comparator IC (7485 IC) DIP-16 Package Buzzer and speakers Recommended operating voltage: 3 ~74HC series ICs are High speed logic gates with very low power consumption that utilize advanced silicon gate CMOS technology and 74HC85 is one of them. 74HC85 ICs contain a 4 bit Comparator that can compare two binary, BCD, or other monotonic codes and present the three possible magnitude results at the output i. e. A>B, A=B, and A<B. And its weighted inputs are A[0: 3] and B[0: 3] where A3 and B3 are MSB. 74HC85 comparator can work in both series
