Table 3-8. PCI Bus AC Specifications for 3.3V Signaling

Symbol	Parameter	Condition	Min	Max	Units	Notes
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
		0.18Vcc>Vout >0		Equation D
	(Test Point)	Vout = 0.18Vcc		38Vcc	mA
Icl	Low Clamp Current	-3 < Vin ≤−1	-25+(Vin +1)/0.015		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.
