The 74HC85PW.112 is a 4-bit magnitude comparator, sometimes referred to as a "ranking comparator," produced by Nexperia. It is used to compare the magnitude of two 4-bit binary words, A and B. If A is less than, equal to, or greater than B, the corresponding output, LT, EQ, and GT, will be set high respectively. The part features a wide operating voltage, low quiescent current, and is designed to work over a wide temperature range, making it suitable for use in a wide range of applications. It is also RoHS compliant, making it suitable for use in environmentally conscious applications.
