Part Number: SN74AVCH4T245

Hi,

What are the minimum and maximum output voltage level VOH and VOL respectively?

I see only VIH and VIL.

Are minimum VOH and VIH levels the same?

Please advise.

Thanks

V_OL and V_OH are specified in section 7.5 (Electrical Characteristics) of the datasheet.

Hi,

My bad for not noticing. Thanks for pointing that out.

If I have VCCA of 1.8V and VCCB of 3.3V. Is it safe to assume the VOL and VOH at these values?

Thanks

These values are specified for slightly lower voltages to allow for the tolerances of actual power supplies.
