PARAMETER	TEST CONDITIONS		V_CC	MIN	TYP	MAX	MIN	TYP	MAX	MIN	TYP	MAX	UNIT
V_OH	V_I = V_IH or V_IL	I_OH = –20 µA	4.5 V	4.4	4.499		4.4			4.4			V
V_OH	V_I = V_IH or V_IL	I_OH = –6 mA	4.5 V	3.98	4.3		3.84			3.7			V
V_OL	V_I = V_IH or V_IL	I_OL = 20 µA	4.5 V		0.001	0.1			0.1			0.1	V
V_OL	V_I = V_IH or V_IL	I_OL = 6 mA	4.5 V		0.17	0.26			0.33			0.4	V
I_I	V_I = V_CC or 0		5.5 V		±0.1	±100			±1000			±1000	nA

I_CC	V_I = V_CC or 0, I_O = 0		5.5 V			8			80			160	µA
∆I_CC⁽¹⁾	One input at 0.5 V or 2.4 V, Other inputs at 0 or V_CC		5.5 V		1.4	2.4			2.9			3	mA
C_i			4.5 V to 5.5 V		3	10			10			10	pF

(1) This is the increase in supply current for each input that is at one of the specified TTL voltage levels, rather than 0 V or V_CC.
