SN74AVC2T244: Output High/Low Voltage

Part Number: SN74AVC2T244


Can you please clarify for me what the output high, min and output low, max voltages are for the SN74AVC2T244, if VCCA = 1.8V and VCCB = 3.3V. The electrical characteristics on data sheet seems ambiguous and reads as if listing values assuming that VCCA = VCCB. 



  • The footnotes talk about VCCO and VCCI, but the table entries never actually use these symbols. And both low and high outputs are specified for VI = VH, which is silly.

    Anyway, the output voltages depend entirely on the characteristics of the output transistors, so you can ignore the VCCA column.
