These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

In test mode, XIN can be driven externally up to f(XTAL) = 130 MHz. If XIN is driven externally, XOUT is floating. § This is a series fundamental crystal with fO = 14.31818 MHz. |
