CD4063 4-bit Magnitude Comparator

The CD4063 is a 4-bit magnitude comparator from the 40xx series CMOS logic family. This device compares two 4-bit binary numbers (A and B) and determines their relative magnitude: A>B, A=B, or A<b. three="" outputs="" indicate="" the="" comparison="" result,="" with="" additional="" cascading="" inputs="" allowing="" multiple="" cd4063="" devices="" to="" be="" combined="" for="" comparing="" larger="" word="" sizes.

The comparator works by evaluating the input bits from most significant to least significant. If the higher-order bits are equal, it proceeds to the next lower pair. This makes the CD4063 suitable for addressing, sorting, and equality detection in data processing systems.
