3 / 24 page Ver2.0 3 LD1018 16 Channel Constant Current Driver DESCRIPTION The LD1018 is specifically designed for LED display applications. The constant current output can be preset through an external resistor (IOUT = 3mA to 45mA). The device consists of 16bit shift register, latch and constant current output driver. The LD1018 provides a constant output current for driving the LEDs against for the variation of LED forward voltage( Vf ). The LD1018’s excellent current matching characteristics among the output ports and fast output response time will give you the best display quality for LED display system. FEATURES • 16 constant-current output channels • Output current : set -up at 3mA to 45mA with an external resistor • Pin to pin deviation : max ± 1.5% • Chip to chip deviation : max ± 3% • 3.3V/5V CMOS compatible input • Delayed output to prevent inrush current • Maximum data transfer rate : max 30MHz • Fast response of OEB - OUTn (min) : 60ns @VDD=5V, 100ns @VDD=3.3V • 3.3V/5V supply voltage • Package : LD1018-SP (SOP-24), LD1018-SS (SSOP-24) • “Pb_free & Green” Package PIN CONNECTION GND DIN CLOCK STROBE OUT0 OUT1 OUT2 OUT3 OUT4 OUT5 OUT6 OUT7 VDD R-EXT DOUT OEB OUT15 OUT14 OUT13 OUT12 OUT11 OUT10 OUT9 OUT8 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 ORDERING INFORMATION -40°C to 85 °C 24 SOP LD1018-SP -40°C to 85 °C 24 SSOP LD1018-SS TA PACKAGE PART NUMBER I-REF Q Q OUT0 OUT1 OUT15 Q 16Bit Shift Register R-EXT OEB STROBE DIN CLOCK DOUT 16Bit Data Latch 16 BLOCK DIAGRAM |
