Hello expert,
My customer would like to double check with below issue in SN74AUP1G08 input voltage level. We applied 3.3V as VCC and raise two inputs to high. The level for VIH minimum is 2V but it seems like output turns high when one input is only reach to 1.59V. May I have your help to check the root cause for it? This happens in every customer's board and customer's board has only one circuit like the email I sent to you. Thanks a lot!!
CH1 = Vina, Ch2 = Vout, Ch3=Vcc, CH4 = Vinb
Best regards,
Ann Lien
