NOTES:
3. An open input will float to the logic-1 state. This feature is not intended as a replacement for an external pull-up resistor when the input is driven
by an open-drain driver.
4. VIH(max) is guaranteed but not tested. Input current is typically less than 2mA at VIH = +4V. In applications requiring +5.5V tolerance, the device
must be driven by a source impedance greater than 1kΩ.
5. Limits established by characterization and are not production tested.
6. Setting is programmable.
