Notes
  • The least significant (or only) comparator in a chain should have IA=B and IA >B tied high and IA <B tied low.
  • To compare more than 4 bits, connect QA <B and QA=B to the inputs of the next significant comparator. IA >B of the next significant comparator should be tied high.

Note
Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
