Switching Characteristics (Notes 4, 9, 11) (Continued)

Note 3: 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

VOD2.

Note 4: All typicals are given for: VCC = +5.0V, TA = + 25˚C.

Note 5: Delta |VOD2| and Delta |VOC| are changes in magnitude of VOD2 and VOC, respectively, that occur when input changes state.

Note 6: Threshold parameter limits specified as an algebraic value rather than by magnitude.

Note 7: Hysteresis defined as VHST =VTH −VTL.

Note 8: IIN includes the receiver input current and driver TRI-STATE leakage current.

Note 9: CL includes probe and jig capacitance.

Note 10: For complete details of test, see RS-485.

Note 11: SR = GND for all Switching Characteristics unless otherwise specified.
