PRODUCTION DATA.
The TLC694x device integrates enhanced circuits to solve the various display issues in fine-pitch LED display applications: the low-grayscale uniformity issue, coupling issue, ghosting issue, and caterpillar issue.
The TLC694x device features an LED-open detection function, and the error detection results can be read via a serial data interface port. Thermal shutdown and IREF resistor short protection ensure a higher system reliability. The TLC694x device also has an smart power-save mode that sets the total current consumption to 1 mA (typical) when all outputs are off.
