They are not meant to imply that the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation. Note 2:Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except: VOD1 and ΔVOD1 . Note 3:All typicals are given for: VCC = +5.0V, TA = +25˚C. Note 4:Channel-to-Channel Skew is defined as the difference between the propagation delay of the channel and the other channels in the same chip with an event on the inputs. Note 5:Chip to Chip Skew is defined as the difference between the minimum and maximum specified differential propagation delays. Note 6:Generator waveform for all tests unless otherwise specified:f=1 MHz, ZO =5 0Ω ,tr ≤ 6 ns, and tf≤ 6 ns. Note 7:ESD Ratings: HBM (1.5 kΩ , 100 pF)≥ 3,500V EIAJ (0Ω , 200 pF)≥ 250V Note 8:Output short circuit current (IOS ) is specified as magnitude only, minus sign indicates direction only. Note 9:C L includes probe and jig capacitance. Note 10:Guaranteed by characterization data (DS90C031E). DS011946-9 FIGURE 7. Driver Output Levels
