Description
CD4532BMS 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 E1 is low.
When E1 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 one input is high, EO is low and all cas-
caded lower-order stages are disabled.
The CD4532BMS is supplied in these 16-lead outline packages:
