flows only when L-level is applied. A single
pin may be loaded with max. 10mA, all pins
together may be loaded with 26mA in all, i.e.
2 pins @ 10mA plus 1pin @ 6mA. Its
possible i.e. to connect and switch a LED
directly. Higher current can be provided by an external transistor circuit.
Note that after Power-On resp. in Power-Save-mode all outputs will be at
H-level.
