(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications.

(3) The maximum limit (V_DDIO + 0.3 V) does not apply to the PDB pin during the transition to the power down state (PDB transitioning from HIGH to LOW).

(4) For soldering specifications: see product folder at www.ti.com and Absolute Maximum Ratings for Soldering (SNOA549).

Bit error rate testing of input to the Ser and output of the Des with 10 meter cable shows no error when the noise frequency on the Ser is less than 50 MHz. The Des on the other hand shows no error when the noise frequency is less than 50 MHz.
