Hi,

I have two questions:

1) For SN74AUC2G04YZPR inverter, what should be the approximate Vin_l at 3.3V VCC. What should be its approximate Vin_l value at 2.7V VCC.

2)What should be your best estimate if my input voltage is ~ 1.4V, does this inverter sense it as logic low or high at 3.3V VCC. Similarly if my input voltage is 1.2V at 3.3V Vcc, does this inverter sense it as logic low or high.

2) What is the right method of measuring Vin_l and Vin_h for an inverter.

For example if I start increasing my input voltage from 0V to some value , what should be the output voltage value where I should measure Vin_l and Vin_h. The ouput voltage for Vin_l should be exact VCC voltage or 0.7*Vcc. Similarly for the measurement of Vin_h the output voltage should be 0.3*Vcc or the lowest output voltage close to zero. We want to standardize the measurement criteria of the inverter in our lab as we use lot of TI inverters in our products.

Thanks for early response,

Syed
