Hi TIer

Does SN74AUC74 support LVCMOS 33 input voltage level?

Thank you very much.

    The highest allowed AUC supply voltage is 2.5 V, but its inputs are overvoltage tolerant up to 3.6 V. This means that the switching thresholds are not exactly the same as for 3.3 V inputs (for 2.5 V, VIL = 0.7 V, VIH = 1.7 V), but it is still possible to connect 3.3 V signals.
