The IC 4527 is a 4-Bit BCD rate multiplier. It produces an output pulse rate equal to the clock input pulse rate multiplied by 1/10 times the BCD input. For instance, if the BCD input is 8, the output will have 8 pulses for every 10 input pulses. This versatile device finds applications in arithmetic operations, solving algebraic and differential equations, generating natural logarithms and trigonometric functions, A/D and D/A conversion, and frequency division.

For fractional multipliers with more than one digit, the IC 4527 is conveniently available in a 16-pin hermetically sealed package. It comes with essential features like ESD Barring and thermal overload protection.

Moreover, it can be easily interfaced with other CMOS, NMOS, and TTL devices. Thus offering seamless integration into various electronic systems.
