This device 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 ) s ( ct DIP ORDER CODES PACKAGE TUBE DIP HCF4527BEY ) s t( T&R c u d o r P input is 8, there will be 8 output pulses for every 10 input pulses. 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 functions, A/D and D/A conversion, 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 October 2002 1/12 HCF4527B INPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No SYMBOL NAME AND FUNCTION 14, 15, 2, 3 10 12 5, 6 9 11 4 13 7 1 BCD Rate Select Inputs Strobe Input Cascade Rate Outputs Clock Input Inhibit Input (Carry) Set Input Clear Input Inhibit Out (Carry) Output 8 A, B, C, D STROBE CASCADE OUT, OUT CLOCK INHIBIT IN SET T0 "9" CLEAR INHIBIT OUT "9" OUT VSS 16 VDD Positive Supply Voltage Negative Supply Voltage FUNCTIONAL DIAGRAM c u d e t le ) s ( ct u d o r P e t e l o s b O 2/12 o s b O - o r P ) s t( HCF4527B TRUTH TABLE INPUTS OUTPUTS Number of Pulses or Logic Level Number of Pulses or Output Logic Level D C B A CLK INH IN STR CAS CLR SET OUT OUT INH OUT "9" OUT L L L L L L L L H H H H H H H H X X X H L X L L L L H H H H L L L L H H H H X X X X X X L L H H L L H H L L H H L L H H X X X X X X L H L H L H L H L H L H L H L H X X X X X X 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 L L L L L L L L L L L L L L L H L L L L L L L L L L L L L L L L L L L L L L H L L L L L L L L L L L L L L L L L L L L L L L H L L L L L L L L L L L L L L L L L L L L L L H H L L L L L L L L L L L L L L L L L L L L L L H L 1 2 3 4 5 6 7 8 9 8 9 8 9 8 9 ** L H 10 L L H 1 2 3 4 5 6 7 8 9 8 9 8 9 8 9 ** H * 10 H H 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 H 1 1 H H L 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ** 1 1 L L H ) s ( ct o s b O - e t le o r P c u d ) s t( X : Don’t Care ** : Depends on internal state of counter. * : Output same as the first 16 lines of this truth table (depending on value of A, B, C, D) u d o r P e t e l o s b O 3/12 HCF4527B LOGIC DIAGRAM c u d e t le ) s ( ct u d o r P e t e l o s b O 4/12 o s b O - o r P ) s t( HCF4527B TIMING CHART c u d e t le u d o ABSOLUTE MAXIMUM RATINGS r P e Symbol VDD II s b O PD Parameter Supply Voltage t e l o VI ) s ( ct DC Input Voltage DC Input Current ) s t( o r P o s b O - Value Unit -0.5 to +22 V -0.5 to VDD + 0.5 ± 10 V mA 200 100 mW mW Top Power Dissipation per Package Power Dissipation per Output Transistor Operating Temperature -55 to +125 °C Tstg Storage Temperature -65 to +150 °C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
