The 24-SSOP package (3.90 mm body width) keeps the board footprint compact for dense sign, display, or indicator arrays where 16 individually dimmable channels are needed per IC. ## Output ratings and thermal limits for the BOM With 16 outputs each at 45 mA, the total sink current is 720 mA — the 24-SSOP's thermal resistance (approx 100 °C/W junction-to-ambient on a standard 2-layer board) means the die temperature stays below 85 °C at 25 °C ambient, but at 85 °C ambient the margin to the 150 °C abs-max junction is tight; a 4-layer board with thermal vias under the package improves headroom. The 35 MHz shift-register clock supports high refresh rates — at 35 MHz the 16-bit data load takes under 500 ns, leaving the bulk of the frame time for PWM dimming duty cycles.","metaTitle":"Texas Instruments TLC59282DBQ LED Driver, 16-Ch, 45mA","metaDescription":"Texas Instruments TLC59282DBQ linear LED driver with shift register, 16 outputs at 45mA each, 35MHz clock, 24-SSOP.
