Nexperia B.V. 4-bit magnitude comparator 74HC85PW,112

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 (QA>B, QA=B and QA ). 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 (IA>B, IA=B and IA ) to the least significant position must be connected as follows: IA = IA>B = LOW and IA=B = HIGH. For words greater than 4-bits, units can be cascaded by connecting outputs QA>B, QA=B and QA to the corresponding inputs of the significant comparator. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 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 standards: JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) ESD protection: HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V Specified from -40 °C to +85 °C and from -40 °C to +125 °C Applications Process controllers Servo-motor control
