SD16730

www.DataSheet4U.com SD16730 8-Bit Constant Current LED Driver DESCRIPTION SD16730 is a special constant current driver for LED display application. The value of constant current can be determined with external resistor. It bases on BICMOS technology and includes an 8bit shift register. Latch and constant current driver. At the output stage, there are eight regulated current sources which provide 280mA constant current for driving LEDs by Bipolar Junction Transistor. SOP-16-300-1.27 FEATURES * Output current adjustable through an external resistor * Serial data in/out * 8 constant-current output channels * Output current: 2-80mA * 20MHz clock frequency * Current accuracy (All output ON) Current accuracy Between Bits <±3% Between ICs <±6% Output current 10 to 60mA DIP-16-300-2.54 APPLICATIONS * LED guardrail diode ORDERING INFORMATION Device SD16730 SD16730S Package DIP-16-300-2.54 SOP-16-300-1.27 Seal SD16730 SD16730S HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http://www.silan.com.cn REV:1.1 2008.11.16 Page 1 of 12 www.DataSheet4U.com SD16730 BLOCK DIAGRAM ABSOLUTE MAXIMUM RATING (Tamb=25°C) Characteristics Supply Voltage Input Voltage Output Current Output Voltage Power Dissipation Storage Temperature Operating Temperature Symbol VDD VIN IOUT VOUT PD1 Tstg Topr Value 6 -0.2~VDD-0.2 90 -0.2~ 17 1.25 -55~+150 -40 ~ 85 Unit V V mA/ch V W °C °C RECOMMENDED OPERATE CONDITION Characteristics Supply Voltage Output Voltage Output Current Symbol VDD VOUT IOUT IOH IOL Input...
