Hello

I'm looking for 7-segments driver.

I have some question regarding to current sinking in the datasheet page 41.

Is the parameter of Io(LEDn) meaning driving current out? or sinking current into the pin?

I didn't see any schematic for current output, the figure 20 is the current sinking.

Thanks,

John

Hello John,

LED0 - LED23 are the LED current sink channels. These pins are connected to the LED cathodes.

Best regards,

Tomas
