NOTES:
2. Open drain output. Contains an active pull-down such that VCC_PWRGD < 0.8V with no +3.3V supplied.
3. Setting is programmable.
4. 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.
5. V
IH
(max) is guaranteed but not tested. Input current is typically less than 2mA at V
IH
= +5V. In applications requiring +5.5V tolerance, the device
must be driven by an open drain or open collector source with a pull-up resistance of no less than 1k
.
6. Guaranteed, but not tested in production.
7. Setting is programmable.
8. Guaranteed by calibration during production test.
