TLC6983 LED Display Driver Texas Instruments TLC6983 LED Display Driver is a highly integrated common-cathode matrix LED display driver with 48 constant current sources and 16 scanning FETs. A single TLC6983 is capable of driving 16 × 16 RGB LED pixels. Stacking two TLC6983s can drive 32 × 32 RGB LED pixels. To achieve low power consumption, the device supports separated power supplies for the red, green, and blue LEDs by its common cathode structure. Furthermore, the operation power of the TLC6983 is significantly reduced by ultra-low operation voltage range (VCC down to 2.5V) and ultra-low operation current (ICC down to 3.9mA).
