Note1: Values have been obtained by applying the test system shown in Fig. 1 and maximum 5,5 V power supply.

Note2: The minimum and maximum showed values are determined by the device’s construction tolerance.

To define the working frequency of the device, add to these values the deviation caused by the thermal variations (see fig. 3).

Note3: To keep the parameters within the limits established by the rules in force, (see para. “Reference Rules”), it is recommended to

supply the circuit with not more than 5,5V and to comply with all the recommendations specified in para “Device usage”.

Messrs AUR°EL declines all responsibilities in case the a.m. recommendations are disregarded.
