Data is accepted on inputs I0 to I7. The binary code HEF4532B MSI corresponding to the highest priority input (I0 to I7) which is HIGH, is generated on O0 to O2 if Ein is HIGH. Input I7 is assigned the highest priority. GS is HIGH when one or more priority inputs and Ein are HIGH. Eout is HIGH when I0 to I7 are LOW and Ein is HIGH. Ein, when LOW, forces all outputs (O0 to O2, GS, Eout) LOW.
