I_CC	V_i = V_CC or 0,	I_O = 0	5.5 V			4		80		40	μA
ΔI_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		3		2.9	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.
