UKŁAD SCALONY: HCF4532BE
HCF4532B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP And SOP packages. HCF4532B consists of a 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 highestpriority 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.
