TC62D748AFG/AFNAG/BFNAG TOSHIBA CDMOS Integrated Circuit Silicon Monolithic TC62D748AFG,TC62D748AFNAG, TC62D748BFNAG 16-Output Constant Current LED Driver (Output TC62D748AFG switching standard-speed version) TC62D748 series are an LED driver with a sink type constant current output. It is the best for lighting the LED module and the LED display. This IC consists of a constant current output circuit of 16 SSOP24-P-300-1.00B outputs, a shift register of 16 bits, a latch of 16 bits, and 16 AND gates. The output current of 16 outputs can be set by one external TC62D748AFNAG/BFNAG resistance. Moreover, high-speed data transfer is possible by adoption of a CMOS process. This IC can operate with the power supply voltage of a 3.3 V system and a 5 V system. The TC62D748 series are RoHS compatible. SSOP24-P-150-0.64 Weight SSOP24-P-300-1.00B : 0.29 g (typ.)
