ADCS7476: VIH

Gust Zhang

Part Number: ADCS7476

Hi, expert,

The datasheet of ADCS7476 says the minimum digital input VIH is 2.4V, is this value a fixed one? Or this value will increase as the VDD? What if I use a 5V VDD and 2.5V digital input logic? Will it cause problems?

Best，

Gust

    Hello Gust,

    I have looked into this, and based on the information available, all indicates that the V_ih level is constant across the power supply range. 

    This parameter is usually spec-ed as Vdd - 0.4V, but unfortunately there is nothing that seems to indicate this applies to this device. 

    Regards
