CD4532 Datasheet PDF

●The CD4532BE is a CMOS 8-bit Priority Encoder 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 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 anyone input is high, EO is low and all cascaded lower-order stages are disabled.

● Converts from 1 of 8 to binary

● Provides cascading feature to handle any number of inputs

● Group select indicates one or more priority inputs

● Standardized, symmetrical output characteristics

● 100% Tested for quiescent current at 20V
