FOR HCC DEICE 100% TESTED FOR QUIESCENT CURRENT MEETS ALL REQUIREMENTS OF JEDEC TEN- TATIE STANDARD N. 13A, STANDARD SPECIFICATIONS FOR DESCRIPTION OF B SERIES CMOS DEICES EY (Plastic Package) F (Ceramic Package) C1 (Chip Carrier) ORDER CODES : HCC4076BF HCF4076BEY HCF4076BC1 PIN CONNECTIONS DESCRIPTION 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 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 arithmetic operatio (add, subtract, divide, raise to a power), solve algebraic and differential equatio, generate naturel logarithms and trigonometric func- September /13

When two units are cascated in Add mode and programmed to 9 and 4 respectively, the more significant 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: = In the multiply mode, the fraction programmed into the first rate multiplier is multiplied by the fraction programmed into the second one: If N1 = 9 and N2 =4 f out2 = 4 10 f out1 f out1 = 9 10 f clock f out2 = f clock = f clock Therefore 36 output pulses for every 100 clock input pulses. 7/13
