The HCC/HCF4532 consists of combinational logic that encodes the highest priority input (D7-D0) to a 3-bit binary code. The eight inputs, D7 through D0, each have an assigned priority. D7 is the highest priority and D0 is the lowest. The priority encoder is inhibited when the chip-enable input El is low. When El is high, the binary representation of the highestpriority input appears on output lines Q2-Q0, and the group select line GS is high to indicate that priority inputs are present. The enable-out (EO) is high when no priority inputs are present. If any one input is high, EO is low and all cascaded lower-order stages are disabled.
