6.4 Output Short Circuit Current

The LMC6772 has short circuit protection of 40mA. However, the comparators are not designed to withstand continuous short circuits, transient voltage or current spikes, or shorts to any voltage beyond the supplies. A resistor in series with the output reduces the effect of shorts. For outputs which send signals off PC boards, use external protection devices such as diodes to the supply rails and varistors.
