CD4527B

The CD4527B is a low-power 4-bit digital rate multiplier that provides an output pulse rate which is the clock-input-pulse rate multiplied by 1/10 times the BCD input. For example, when the BCD input is 8, there will be 8 output pulses for every 10 input pulses.This device may be used to perform arithmetic operations(add,substract,divide, raise to a power), solve algebraic and differential equations, generate natural logarithms and trigonometric functions, A/D and D/A conversion, and frequency division.

Features of the CD4527B are:(1)cascadable in multiples of 4-bits; (2)100% tested for quiescent current at 20 V; (3)set to "9"input and "9" detect otuput; (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 CD4527B 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.
