DESCRIPTION

HCF4089B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP and SOP packages.

HCF4089B is a low power 4-bit digital rate

multiplier that provides an output pulse rate that is

the clock input pulse rate multiplied by 1/16 times

the binary input. For example, when the binary

input number is 13, ther will be 13 output pulses

for every 16 input pulses.

HCF4089B has an internal synchronous 4-bit

counter, which, together with one of the four

binary inputs bits, produces pulse trains as shown

in the timing diagram.

If more than one binary input bit is high, the

resulting pulse train is a combination of the above

separate pulse trains. This device may be used to

perform arithmetic operations (add, subtract,

divide, raise to a power), solve algebrical and

differential equations, generate natural logarithms

and trigonometric functions, A/D and D/A

conversions, and frequency division.
