Re: 300 mA from a microcontroller pin

I assumed the OP wanted to put the 16 LEDs in a 4x4 grid, and
control them with 8 pins on the PIC (4 row and 4 column), which
would require tri-state control.

However, using discrete components is probably the easiest
solution (assuming there's space on the board).

And there is no driver dissipation power problem if saturating
drivers are used. Typical sat voltage is about 0.3 V., which, at
300 mA, means about 0.1 watts.
