Note 5.1 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 5.2 This rating does not apply to the following pins: XTAL1/CLKIN, XTAL2, RBIAS.

Note 5.3 This rating does not apply to the following pins: RBIAS.

Note 5.4 0℃ to +85℃ for extended commercial version, -40℃ to +85℃ for industrial version.

Note 5.5 Performed by independent 3rd party test facility
