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.
