  1. Hello! I am currently designing some electronics using the Concerto ControlCARD. On the controlCARD, TI is using the SN74LVC2G07DBVR to drive two LEDs. Assuming that the forward voltage of the diode is approximately 1.2V, the LED current is about (3.3V-1.2V)/680Ohm = 3mA. The PINs of the F28M35x are specified for 4mA max. which means it should be perfectly capable of driving the LEDs without the driver. For my understanding the driver is not really needed? Do i miss something else/important? Thank you very much in advance! Kind regards Stefan
