| TOSHIBA Bi-CMOS Constant Current Interface Driver TB62710P/F Product Description: 8 Bit Constant Current LED Source Driver with Shift Register and Latch Functions The TB62710P/F are specifically designed for LED display applications. The Bi-CMOS device has 8 Bipolar constant current output source channels and includes CMOS shift register and latch functions. The LED drive current is programmed by the installation of a single resistor per device. Current is programmable from 5-90mA and is held constant across all 8 source outputs effectively compensating for the inherent circuit and component variables which affect the brightness of the LEDs. Features: Current Source Device 8 Constant Current Output Channels Current Programmable from 5-90mA 5V CMOS Compatible Inputs Available in Thru Hole and Surface Mount Packages 15MHz max Clock Frequency (Cascade, Ta = 25C) Block Diagram: marktech optoelectronics 120 Broadway Menands, New York 12204 Toll Free: (888) 4LED-ICS Fax: (518) 432-7454 All specifications subject to change. 1 TOSHIBA Bi-CMOS Constant Current Interface Driver TB62710P/F Timing Diagram: Terminal Description & Pin Out: PIN No. PIN NAME P type 1 2 3 4 7~14 17 18 16 19 20 6,15 5 F type 1 2 3 5 9~16 21 22 20 23 24 7,18 4,6,8,17,19 GND SERIAL-IN CLOCK LATCH OUT0~7 ENABLE SERIAL-OUT1 SERIAL-OUT2 R-EXT VDD VCC NC GND terminal for control logic Input terminal of a serial-data for shift-register Input terminal of a clock for data shift to up-edge.
