IOOutput current with power offVCC = 0, VO = –7 V to 12 V±100µA
IOZHigh-impedance-state output currentVO = –7 V to 12 V±100µA

IILLow-level input currentVI = 0.4 V–100µA
IOSShort-circuit output currentVO = –7 V to 12 V±250mA
ICCSupply current (all drivers)No loadOutputs enabled3655mA

All typical values are at VCC = 5 V and TA = 25°C.
The minimum VOD2 with a 100-Ω load is either 1/2 VOD1 or 2 V, whichever is greater.
Δ|VOD| and Δ|VOC| are the changes in magnitude of VOD and VOC, respectively, that occur when the input is changed from a high level to a low level.
In ANSI Standard EIA/TIA-422-B, VOC, which is the average of the two output voltages with respect to ground, is called output offset voltage, VOS.
