(1) For thermal pad size on the package, see the mechanical drawings at the end of this data sheet. θ_JA = 25.41° C/W (0LFM air flow),
θ_JC = 16.5°C/W when used with 2oz. copper trace and pad soldered directly to a JEDEC standard four layer 3 in x 3 in (7.62 cm x 7.62
cm) PCB.
(2) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. 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.
(2) When AVDD is turned off, it is recommended to switch off the input clock (or ensure the voltage on CLKP, CLKM is < |0.3V|. This
prevents the ESD protection diodes at the clock input pins from turning on.
