PARAMETER		TEST CONDITIONS		V_CC	T_A = 25°C			SN54HCT139		SN74HCT139		UNIT
PARAMETER		TEST CONDITIONS		V_CC	MIN	TYP	MAX	MIN	MAX	MIN	MAX	UNIT
V_OH	High level output voltage	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	High level output voltage	V_I = V_IH or V_IL	I_OH = −4 mA	4.5 V	3.98	4.3		3.7		3.84		V
V_OL	Low level output voltage	V_I = V_IH or V_IL	I_OL = 20 µA	4.V		0.001	0.1		0.1		0.1	V
V_OL	Low level output voltage	V_I = V_IH or V_IL	IO_L = 4 mA	4.V		0.17	0.26		0.4		0.33	V
I_I	Input leakage current V	V_I = V_CC or 0		5.5 V		±0.1	±100		±1000		±1000	nA
I_CC	Supply current	V_I = V_CC or 0	I_O = 0	5.5 V			8		160		80	µA
ΔI_CC⁽¹⁾	Supply-Current Change	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	Input Capacitance			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.
