Δ|VOC| Change in magnitude of common-mode output voltage(3) ±0.2 V
IO Output current VCC = 0 VO = -7V to 12V ±100 µA
IIH High-level input current VIH = 2.4V 20 µA
IIL Low-level input current VIL = 0.4V –200 µA
IOS Short circuit output current VO = –7V –250 mA
VO = VCC 250
VO = 12V 250
ICC Supply current (total package) No load 57 70 mA
(1) All typical values are at VCC = 5V and TA = 25°C.
(2) The minimum VOD2 with 100Ω load is either 1/2 VOD2 or 2V, whichever is greater
(3) 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.
