The HCC4527B (extended temperature range) and
HCF4527B (intermediate temperature range) are
monolithic integrated circuit, available in 16-lead
dual in line plastic or ceramic package.
The HCC/HCF4527B 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 preform arith-
metic operations (add, subtract, divide, raise to a
power), solve algebraic and differential equations,
generate naturel logarithms and trigonometric func-

APPLICATION NOTE
For fractional multipliers with more than one digit,
HCC/HCF4527B devices may be cascated in two
different modes: the Add mode and the Mltiply mode
(see figures 1 and 2).
When two units are cascated in Add mode and pro-
grammed to 9 and 4 respectively, the more signifi-
cant unit will have 9 output pulses for every 10 input
pulses and the other unit will have 4 output pulses
for every 100 input pulses for a total of:
9
10
+
4
100
=
94
100
In the multiply mode, the fraction programmed into
the first rate multiplier is multiplied by the fraction
programmed into the second one:
If N
1
= 9 and N
2
= 4
f
out2
=

Therefore 36 output pulses for every 100 clock input
pulses.
