... Typical Operating Characteristics on page Logic Inputs The AS1741/AS1742/AS1743 logic inputs can be driven up to +3.6V regardless of the supply voltage value. For exam- ple, with a +1.8V supply may be driven low to GND and high to +3.6V. This allows the devices to interface with +3V systems using a supply of less than 3V. ...
