.. 16 Channel Constant current output LED Driver 16 Channel Constant current output LED Driver Data Sheet 2004. 4 SD-2001A 1/13 .. 16 Channel Constant current output LED Driver DESCRIPTION The LD71D0016 is specifically designed for LED and LED DISPLAY constant current drivers. This constant current output circuit is able to set up external resistor (IOUT = 5m A to 90m A). The devices consist of 16bit shift register, latch, and-gate and constant current driver. SDIP24-P-300 Weight : 1.20g (Typ.) Features - Output current : set-up at 5m A to 90m A with an external resistor - A little change of output current OUT-GND VOLTAGE > 0.7V + 6% > 1.0V A LITTLE CHANGE OF CHANNEL IOUT (m A) 5m A ~40m A 5m A ~90m A GND DIN CLOCK STROBE OUT0 OUT1 OUT2 OUT3 OUT4 OUT5 OUT6 OUT7 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 VDD R-EXT DOUT OE OUT15 OUT14 OUT13 OUT12 OUT11 OUT10 OUT9 OUT8 - 5V CMOS patible Input - Package : SDIP-24, PDIP-24, SSOP-24, SOP-24 - Maximum Clock Frequency : f MAX = 25MHz PIN CONNECTIONS (TOP VIEW) PIN DESCRIPTION PIN NO. 1 2 3 4 24 5~12 13~20 21 22 23 PIN NAME GND DIN CLOCK STROBE VDD OUTn OE DOUT R-EXT DESCRIPTION GND terminal for control logic driver Serial data input terminal for shift register Clock input terminal for data shift to up-edge “H” level : data through, “L” level : data hold Supply voltage terminal Output terminals “H” level output off, “L” level : latch data = “H” level then output on, latch data = “L” level then output off Serial data output terminal for shift register The resistor which connects between R-EXT and GND sets the constant output current.
