5.4 AC Electrical Characteristics

The following specification apply for V+ = +3.0VDC to +3.6VDC, unless otherwise specified. Boldface limits apply for TA = TJ = TMIN to TMAX; all other limits TA = TJ = 25 °C. The SensorPath Characteristics conform to the SensorPath specification. Please refer to that specification for further details.

(1) “Typicals” are at TA = 25 °C and represent most likely parametric norm. They are to be used as general reference values not for critical design calculations.
(3) Limits are specified to TI's AOQL (Average Outgoing Quality Level).
(3) This specification is provided only to indicate how often temperature data is updated once enabled.
(4) The output fall time is measured from VIH min to VIL max. The output fall time is ensured by design.
(5) The output rise time is measured from VIL max to VIH min. The output rise time is ensured by design.
