DESCRIPTION
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
inhibited when the chip-enable input E l is low. When
E l 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 (E O )ishighwhen
no priority inputs are present. If any one input is high,
E O is low and all cascaded lower-order stages are
disabled.
