4-bit Magnitude Comparator IC - 74HC85
The 74HC Series 74HC85 are high-speed Si-gate CMOS devices and are pin-compatible with low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC85 IC are 4-bit magnitude comparators that can be expanded to almost any length. They perform the 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 QAB, IA=B and IAB = = LOW and IA=B = HIGH. For words greater than 4-bits, units can be cascaded by connecting outputs QAΒ and QA=B to the corresponding inputs of the significant comparator.

What is 4-bit comparator IC 7485?
- The 4-bit comparator is mostly available in IC form, with the most common type being 7485. By grounding I (A>B), I (A as analog-to-digital converters (ADCs), and I (A as relaxation oscillators, this IC can be used to compare two 4-bit binary words.
What is the application of IC 7485?
- The IC 7485 compares the magnitude of two binary numbers. The two 4-bit numbers are applied to the A3,A2,A1,A0 and B3,B2,B1,B0 inputs. Where A3 and B3 are the most significant bits of the two 4-bit operands under consideration.
What is comparator used for?
- A comparator is made up of a highly specialised high-gain differential amplifier. They are commonly used in analog-to-digital converters (ADCs) and relaxation oscillators, which measure and digitise analogue signals.
