TC62D748CFNAG TOSHIBA CDMOS Integrated Circuit Silicon Monolithic TC62D748CFNAG 16-Output Constant Current LED Driver The TC62D748CFNAG is a constant-current driver for LED and LED display lighting applications. The output current from each of the 16 outputs is programmable via a single external resistor. The TC62D748CFNAG contains a 16-channel shift register, a 16-channel latch, a 16-channel AND gate and a 16-channel constant-current output. P-SSOP24-0409-0.64-001 Fabricated with a CMOS process, the TC62D748CFNAG allows high-speed data transfer. Weight: 0.14 g (Typ.) It operates with a 3.3- or 5-V power supply.
