Part Number : HEF4585B
Function : 4-bit, Magnitude Comparator
Package : DIP 16 Pin
Maker : NXP Semiconductors.
Pinouts : 
Description :
The HEF4585B is a 4-bit magnitude comparatorthat compares two 4-bit words, A and B, and determines whether A is greater than B, A is equal to B, or A is less than B. Each word has four parallel inputs (A0 to A3 and B0 to B3) with A3 and B3 being the most significant inputs.
