DESCRIPTION
TheHCC4527B (extended temperature range) and
HCF4527B (intermediate temperature range) are
monolithic integrated circuit, available in 16-lead
dual in line plastic or ceramicpackage.
TheHCC/HCF4527Bisalow power4bitdigital rate
multiplier thatprovidesan output pulserate whichis
theclockinputpulseratemultipliedby1/10timesthe
BCD input. For example, when the BCDinput is 8,
there will be 8 output pulses for every 10 input
pulses. This device may be used to preform arithmetic operations (add, subtract, divide, raise to a
power), solve algebraic and differential equations,
generate naturel logarithms and trigonometric func-
