Note 4-1 When powering this device from laboratory or system power supplies, it is important that the absolute
maximum ratings not be exceeded or device failure can result. Some power supplies exhibit voltage
spikes on their outputs when AC power is switched on or off. In addition, voltage transients on the
AC power line may appear on the DC output. If this possibility exists, it is suggested that a clamp
circuit be used.
Note 4-2 This rating does not apply to the following pins: XI, XO, EXRES, USBRBIAS.
Note 4-3 This rating does not apply to the following pins: EXRES, USBRBIAS.
Note 4-4 0°C to +70°C for commercial version, -40°C to +85°C for industrial version.
Note 4-5 Performed by independent 3rd party test facility.
*Stresses exceeding those listed in this section could cause permanent damage to the device. This is a stress rating
only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Functional
operation of the device at any condition exceeding those indicated in Section 4.2, "Operating Conditions**", Section 4.4,
"DC Specifications", or any other applicable section of this specification is not implied. Note, device signals are NOT
5 volt tolerant unless specified otherwise.

4.3 Power Consumption
This section details the power consumption of the device as measured during various modes of operation. Power dis-
sipation is determined by temperature, supply voltage, and external source/sink requirements.
