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
The TPD12S521 provides an on-chip regulator with current output ratings of 55 mA at pin 38. This current
enables HDMI receiver detection even when the receiver device is powered off. DBT package pitch (0.5 mm)
matches with HDMI connector pitch. In addition, pin mapping follows the same order as the HDMI connector pin
mapping. This HDMI receiver port protection and interface device is specifically designed for next-generation
HDMI transmitter protection.
