Compared to other logic families, the LVxT family is the most well-rounded and universal in terms of specifications. The LVxT family of devices combines a reduced input threshold voltage with a wide supply range, allowing for up or down voltage translation with only one power rail. The family has overvoltage-tolerant inputs that allow down translation from up to 5.5 V down to the supply voltage, which can be as low as 1.6 V. The reduced input thresholds allow for up-translation from inputs as low as 2.03 V up to 5-V outputs. See the list below for a summary of common voltage nodes and translation combinations supported.
