NOTES:
1. Measured as HIGH above V IH and LOW below V IL .
2. Transition is measured ±200mV from steady-state.
3. Device must be deselected when powered-up from sleep mode.
4. t CFG is the minimum time required to configure the device based on the LBO input. LBO is a static input and must not change during normal operation.
5. Commercial temperature range only.
