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 ) s ( ct DIP SOP ORDER CODES PACKAGE TUBE DIP SOP HCF4089BEY HCF4089BM1 ) s t( T&R c u d HCF4089M013TR o r P 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. e t le o s b O - u d o r P e t e l o PIN CONNECTION s b O September 2002 1/11 HCF4089B IINPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No SYMBOL NAME AND FUNCTION 14, 15, 2, 3 5 6 4 1 Binary Rate Select Inputs Rate Output Rate Output Set Input Output 8 A, B, C, D OUT OUT SET TO "15" "15" OUT INHIBIT OUT (CARRY) CLEAR CASCADE INHIBIT IN (CARRY) STROBE CLOCK VSS 16 VDD 7 13 12 11 10 9 Inhibit Out (Carry) Clear Input Cascade Inhibit Input (Carry) Strobe Clock Input Negative Supply Voltage c u d FUNCTIONAL DIAGRAM e t le ) s ( ct u d o r P e t e l o s b O 2/11 o s b O - ) s t( Positive Supply Voltage o r P HCF4089B TRUTH TABLE INPUTS OUTPUTS Number of Pulses or Input Logic Level Number of Pulses or Output Logic Level D C B A CLOCK INH IN STR.
