It is quite important to be aware of the limitations of the device when used for switching output devices. You should be aware of these limitations at all times. Exceeding these values even for a short time may cause permanent damage to the PICmicro.
Fortunately the E-blocks you will use on this course all have current limiting resistors which will protect your PICmicro device. When using the prototype or patch board you will have no such protection and care must be taken not to damage your device. (:nl:)(:table style="clear:both":)
