This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
DESCRIPTION (CONTINUED)
As part of the THS7313 flexibility, the 2:1 MUX input can be selected for ac or dc coupled inputs. The ac coupled
modes include a sync-tip clamp option for CVBS or Y' signals, or a fixed bias for the C/P'_B/P'_R channels. The dc
input options include a dc input or a dc + 135-mV input offset shift to allow for a full sync dynamic range at the
output with 0-V input.

(1) Stresses above 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 degrade device reliability.
(2) The absolute maximum junction temperature under any condition is limited by the constraints of the silicon process.
(3) The absolute maximum junction temperature for continuous operation is limited by the package constraints. Operation above this
temperature may result in reduced reliability and/or lifetime of the device.

(1) Power rating is determined with a junction temperature of 125°C. This is the point where distortion starts to substantially increase and
long-term reliability starts to be reduced. Thermal management of the final PCB strives to keep the junction temperature at or below
125°C for best performance and reliability.
(2) This data was taken with the JEDEC High-K test PCB. For the JEDEC low-K test PCB, the θ_JA is 125.8°C.
