CD4527BE

TEXAS INSTRUMENTS  CD4527BE  逻辑芯片, BCD码比率乘法器, 16DIP

The 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, subtract, 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. For fractional multipliers with more than one digit, CD4527B devices may be cascaded in two different modes: the Add mode and the Multiply mode.
