Typical specifications are estimations only and are not ensured. (2) Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground except VOD, ΔVOD, VTH and VTL which are differential voltages. (3) Typical values represent most likely parametric norms at 1.8V or 3.3V, TA = +25°C, and at the Recommended Operation Conditions at the time of product characterization and are not ensured. 8 Submit Documentation Feedback Copyright © 2010–2013, Texas Instruments Incorporated Product Folder Links: DS90UB903Q DS90UB904Q |
