Blackmagic ATEM Mini Pro mainboard — HDMI input rails
I suspect this IC is an ESD protection device on the HDMI input rails. Could you please help me identify the IC/part number? Thank you.

Hi Adam7
Thanks for your help, but I think this is an ESD protection IC, not a dual buffer gate.
Hi Adam7,
I already checked:
Pin 2 = GND
Pin 3 = VCC
Thank you very much for your help ![]()
Please be aware that SN74LVC2G34DCKRG4 is discontinued in our system. I would advise checking out the alternates listed on the top of the product page.
