IOH(AC) Switching Current High 0<Vout <0.3Vcc -12Vcc mA
0.3Vcc<Vout <0.9Vcc -17.1(Vout -Vout) mA
0.7Vcc<Vout <Vcc Equation C
(Test Point) Vout = 0.7Vcc -32Vcc mA
IOL(AC) Switching Current Low Vout > Vout>0.6Vcc 16Vcc mA
0.6Vcc>Vout> 0.1Vcc Vout /0.023 mA

Ich High Clamp Current Vcc+4 > Vin > Vcc+1 25+(Vin -Vcc +1)/0.015 mA
slew r Output Rise Slew Rate 0.2Vcc - 0.6Vcc load 1 5 V / ns
slew f Output Fall Slew Rate 0.6Vcc - 0.2Vcc load 1 5 V / ns
Notes:
Equation C: Ioh = (0.98/Vcc) * (Vout - Vcc) * (Vout + 0.4Vcc) for Vcc > Vout > 0.7Vcc.
Equation D: Iol = (256/Vcc) * Vout * (Vcc - Vout) for 0V < Vout < 0.18Vcc.
