TI TLC5920DLR

The TLC5920 is an LED driver incorporating a 16-channel shift register, data latch, and constant current circuitry with current value control and 8-channel common driver into a single chip. The constant output current is capable of 30 mA for 16 bits simultaneously, and the current value can be set by one external register. This device also includes a 16-bit segment driver and 8-bit common driver; therefore, the monocolor LED array with 16×8 dots can be driven by only one TLC5920, and a two-color LED array with 16×16 dots can be driven by two TLC5920s.
