4.5 Electrical Characteristics

over recommended operating free-air temperature range (unless otherwise noted)

PARAMETER	TEST CONDITIONS		V_CC	T_A = 25°C			MIN	MAX	UNIT
PARAMETER	TEST CONDITIONS		V_CC	MIN	TYP	MAX	MIN	MAX	UNIT
V_OH	I_OH = −50µA		4.5V	4.4	4.5		4.4		V
V_OH	I_OH = −8mA		4.5V	3.94			3.8		V
V_OL	I_OL = 50µA		4.5V			0.1		0.1	V
V_OL	I_OL = 8mA		4.5V			0.36		0.5	V
I_I	V_I = 5.5V or GND		0 V to 5.5 V			±0.1		± 1	µA
I_CC	V_I = V_CC or GND,	I_O = 0	5.5V			4		40	µA
∆_ICC1	One input at 3.4 V, Other inputs at V_CC or GND		5.5V			1.35		1.5	mA
C_i	V_I = V_CC or GND		5V		2	10			pF

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