DESCRIPTION
HCF4527B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP package.
This device 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.
