CD4532B

The CD4532B 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 has 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.

Features of the CD4532B are:(1)converts from 1 of 8 to binary; (2)100% tested for quiescent current at 20 V; (3)provides cascading feature to handle any number of input; (4)maximum input current of 1 uA at 18 V over full package-temperature range;100 nA at 18 V and 25; (5)standardized, symmetrical output characteristics.

The absolute maximum ratings of the CD4532B can be summarized as:(1): DC supply-voltage range(VDD) is -0.5 V to +20 V(voltages referenced to Vss terminal); (2): input voltage range, all inputs is -0.5 V to VDD+0.5 V; (3): DC input current, any one input is ±10 mA; (4): operating temperature range(Ta) is -55 to +125; (5): storage temperature range(Tstg) is -65 to +150.
