Dual Voltage LVCMOS I2C DC Electrical Characteristics (continued) PARAMETER MIN NOM MAX UNIT IOZ IOZ(IPAD Current) for BIDI cell. This current is 12 µA contributed by the tristated driver leakage + input current of the Rx + weak pullup/pulldown leakage. PAD is swept from 0 to VDDS and the Max(I(PAD)) is measured and is reported as IOZ CIN Input capacitance 10 pF VOL3 Output low-level threshold open-drain at 3-mA 0.2*VDDS V sink current IOLmin Low-level output current @VOL=0.2*VDDS 3 mA tOF Output fall time from VIHmin to VILmax with a bus 20+0.1*Cb 250 ns capacitance CB from 10 pF to 400 pF I2C Standard Mode – 3.3 V VIH Input high-level threshold 0.7*VDDS V VIL Input low-level threshold 0.3*VDDS V Vhys Hysteresis 0.05*VDDS V IIN Input current at each I/O pin with an input voltage 31 80 µA between 0.1*VDDS to 0.9*VDDS IOZ IOZ(IPAD Current) for BIDI cell. This current is 31 80 µA contributed by the tristated driver leakage + input current of the Rx + weak pullup/pulldown leakage. PAD is swept from 0 to VDDS and the Max(I(PAD)) is measured and is reported as IOZ CIN Input capacitance 10 pF VOL3 Output low-level threshold open-drain at 3-mA 0.4 V sink current IOLmin Low-level output current @VOL=0.4V 3 mA IOLmin Low-level output current @VOL=0.6V for full drive 6 mA load (400pF/400KHz) tOF Output fall time from VIHmin to VILmax with a bus 250 ns capacitance CB from 5 pF to 400 pF I2C Fast Mode – 3.3 V VIH Input high-level threshold 0.7*VDDS V VIL Input low-level threshold 0.3*VDDS V Vhys Hysteresis 0.05*VDDS V IIN Input current at each I/O pin with an input voltage 31 80 µA between 0.1*VDDS to 0.9*VDDSS IOZ IOZ(IPAD Current) for BIDI cell. This current is 31 80 µA contributed by the tristated driver leakage + input current of the Rx + weak pullup/pulldown leakage. PAD is swept from 0 to VDDS and the Max(I(PAD)) is measured and is reported as IOZ CIN Input capacitance 10 pF VOL3 Output low-level threshold open-drain at 3-mA 0.4 V sink current IOLmin Low-level output current @VOL=0.4V 3 mA IOLmin Low-level output current @VOL=0.6V for full drive 6 mA load (400pF/400KHz) tOF Output fall time from VIHmin to VILmax with a bus 20+0.1*Cb 250 ns capacitance CB from 10 pF to 200 pF (Proper External Resistor Value should be used as per I2C spec) Output fall time from VIHmin to VILmax with a bus 40 290 capacitance CB from 300 pF to 400 pF (Proper External Resistor Value should be used as per I2C spec) Copyright © 2014–2015, Texas Instruments Incorporated Specifications 185 Submit Documentation Feedback Product Folder Links: AM5728 AM5726 |
