CD4585B

The CD4585B is a 4-bit magnitude comparator designed for use in computer and logic applications that require the comparison of two 4-bit words.This logic circuit determines whether one 4-bit word(binary or BCD) is "less than","equal to". or "greater than" a second 4-bit word.

Features of of the CD4585B are:(1)expansion to 8,12,16...4N bits by cascading units; (2)100% tested for quiescent current at 20 V; (3)standardized symmetrical output characteristics; (4)5 V, 10 V and 15 V parametric ratings; (5)maximum input current of 1 uA at 18 V over full package-temperature range;100 nA at 18 V and 25

The absolute maximum ratings of the CD4585B 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.
