Each output is an open-drain current-sinking output rated to 50mA at 7V. All outputs are capable of driving LEDs, or providing logic outputs with external resistive pullup up to 7V. Eight-bit PWM current control is also integrated. Four of the bits are global control and apply to all LED outputs to provide coarse adjustment of current from fully off to fully on with 14 intensity steps. Additionally each output then has an individual 4-bit control, which further divides the globally set current into 16 more steps.
