Hello,

I have a question about 5V tolerant pins of ADV7611.

 

Question :
 Do all of following pins support 5V tolerant?

 (A signal below 5.3V can input to these pins without power.)

 1pin HPA_A/INT2
 62pin DDCA_SCL
 63pin DDCA_SDA
 64pin RXA_5V

 

 Datasheet says:
  On Page 4,  The following pins are 5 V tolerant: DDCA_SCL, DDC_SDA, and RXA_5V.
  On Page 7,  The following inputs are 3.3 V inputs but are 5 V tolerant: DDCA_SCL and DDCA_SDA.
  On Page 8,  HPA_A/INT2 Miscellaneous digital A dual function pin that can be configured to output

                      a Hot Plug assert signal (for HDMI Port A) or an Interrupt 2 signal. This pin is 5 V tolerant.
  On Page 9,  62 DDCA_SCL HDMI input HDCP Slave Serial Clock Port A. DDCA_SCL is a 3.3 V input

                      that is 5 V tolerant.
                      63 DDCA_SDA HDMI input HDCP Slave Serial Data Port A. DDCA_SDA is a 3.3 V input

                      that is 5 V tolerant.

 

Thank you!
Best regards.
