74HC85 4-Bit Comparator IC (7485 IC) DIP-16 Package Buzzer and speakers These are Carbon Film Resistor74HC 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
