DESCRIPTION
The
HCC4089B
(extended temperature range) and
HCF4089B
(intermediate temperature range) are
monolithic integrated circuit available in 16-lead
dual in-line plastic or ceramic package.
The
HCC/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, there will be 13 output pulses for every
16 input pulses.
The
HCC/HCF4089B
has an internal synchronous
4-bit counter which, together with one of the four bi-
nary input bits, produces pulse trains as shown in
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 algebraic and differential equations,
generate natural logarithms and trigonometric func-
tions, A/D and D/A conversions, and frequency di-
vision.
