Note 2: All units are 100% production tested at +25ºC. All temperature limits are guaranteed by design.

Note 3: Phase measurement is in relation to the rising edge of VLX_.

Note 4: Guaranteed by design. Not production tested.

Electrical Characteristics (continued)

(VA = VPV1 = VPV2 = VPV3 = VPV4 = 5.0V; TA = TJ = -40ºC to +125ºC, unless otherwise noted. Typical values are at TA = +25ºC under

normal conditions, unless otherwise noted.) (Note 2)
