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.
