The HCC4532B (extended temperature range) and

HCF4532B (intermediate temperature range) are

monolithic integrated circuit, available in 16-lead

dual in-line plastic or ceramic package and plastic

micro package.

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

priority input appears on output lines Q2-Q0, and the

group select line GS is high to indicate that priority

no priority inputs are present. If any one input is high,

disabled.
