74HC85; 74HCT85 4-bit magnitude comparator Rev. 3 — 20 April 2018 Product data sheet 1 General description The 74HC85; 74HCT85 is a 4-bit magnitude comparator that can be expanded to almost any length. They perform comparison of two 4-bit binary, BCD or other monotonic codes and present the three possible magnitude results at the outputs (Q , Q and Q ). A>B A=B A<B The 4-bit inputs are weighted (A0 to A3 and B0 to B3), where A3 and B3 are the most significant bits. For proper compare operation the expander inputs (I , I and I ) A>B A=B A<B to the least significant position must be connected as follows: I = I = LOW A<B A>B and I = HIGH. For words greater than 4-bits, units can be cascaded by connecting A=B outputs Q , Q and Q to the corresponding inputs of the significant comparator. A>B A=B A<B Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2 Features and benefits • Wide supply voltage range from 2.0 to 6.0 V • CMOS low power dissipation • High noise immunity • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B • Input levels: –For 74HC85: CMOS level –For 74HCT85: TTL level • Complies with JEDEC standard: no. 7A –JESD8C (2.7 V to 3.6 V) –JESD7A (2.0 V to 6.0 V) • ESD protection: –HBM JESD22-A114-A exceeds 2000 V –MM JESD22-A115-A exceeds 200 V • Specified from -40 °C to +85 °C and from -40 °C to +125 °C 3 Applications • Process controllers • Servo-motor control
