4-bit Magnitude Comparator IC - 74HC85 Compatible With Arduino 52 APM Flight Controllers4 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,
