Description
The HDMI05-CL02F3 chip is a low capacitance
R3
ESD protection for HDMI control pins. It also
integrates pull-up resistor for I²C bus and pulldown resistor for hot plug detect and pull-up
resistor for CEC line.
B2 and C2 are ground pins
The ESD protection circuitry prevents damage to
the protected device when subjected to ESD
surges up to 15 kV.
