question about the TS5USBA224

What is minimum threshold voltage of Vaudio and Vbus being High?

Is it same as Vih which is 1.2V?

Thank you,

Ranita

    Ranita,

    The recommended operating conditions for the Vbus and Vaudio can be seen below.  This is a snap shot of a new version of this datasheet I am working on.  I would love to rename the pin name Vaudio to Vcc and Vbus to IN or SEL to help eliminate some confusion which is the IC supply voltage and which is a logic input.  Unfortunately,  I cannot change the pin names without causing heartache with our existing customers. 

    Vaudio pin is actually the supply voltage to the IC even though it is in included in the logic truth table above.  For the IC to be correctly powered up a minimum of 2.7 V is required. 

    For the logic input pin Vbus the minimum voltage on the VBUS pin for the device to recognize a logic "high" (Vih) is 1.2 V. 

    Thank you,

    Adam
