TLC6984 48x16 Matrix LED Display Driver Texas Instruments TLC6984 48x16 Matrix LED Display Driver is a highly-integrated common cathode matrix LED display driver with 48 constant current sources and 16 scanning FETs. Besides driving 16 × 16 and 32 × 32 RGB LED pixels as TLC6983, three TLC6984s are capable of driving 48 × 48 RGB LED pixels, and stacking four TLC6984s can drive 64 × 64 RGB LED pixels. The device supports separated power supplies for the red, green, and blue LEDs by its common cathode structure to achieve low power consumption. Furthermore, the operation power of the TLC6984 is significantly reduced by ultra-low operation voltage range (VCC down to 2.5V) and ultra-low operation current (ICC down to 3.6mA).
