They are not meant to imply that the devices should be operated at these limits. The tables of “Electrical Characteristics” specify conditions for 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 unless otherwise speci- fied. Note 3:Δ |VT1| andΔ |VOS | are changes in magnitude of VT1 and VOS , respectively, that occur when the input changes state. Note 4:All typicals are given for VCC = 5.0V and TA = +25˚C. Note 5:Threshold parameter limits specified as an algebraic value rather than by magnitude. Note 6:Hysteresis defined as VHST =V TH −V TL. Note 7:IIN includes the receiver input current and driver TRI-STATE leakage current. www.national.com3
