DESCRIPTION

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 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 thegroup select lineGS is highto

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.
