Parameter Rating Unit Supply Voltage -0.5 to +6.0 V Exceeding any one or a combination of the Absolute Maximum Rating conditions may DC cause permanent damage to the device. Extended application of Absolute Maximum Rating conditions to the device may reduce device reliability. Specified typical perfor- Input RF Level +5 (see note) dBm mance or functional operation of the device under Absolute Maximum Rating condi- tions is not implied.

Input RF transients to +15dBm will not harm the device. For sustained operation at inputs >+5dBm, a small dropping resistor is recommended in series with the V in order to limit the current due CC to self-biasing to <32mA.
