CD4532BM

LOGIC, 8BIT PRIORITY ENCODER, 16SOIC.

The CD4532BM is a 8-bit CMOS Priority Encoder consists of combinational logic that encodes the highest priority input (D7 to 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 EI is low. When EI is high, the binary representation of the highest-priority 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 input is high, EO is low and all cascaded lower-order stages are disabled.
