over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)⁽²⁾ (see Figure 9-1)

PARAMETER		TEST CONDITIONS	MIN	TYP⁽¹⁾	MAX	UNIT
V_OH	High-level output voltage	I_OH = −1 mA	V_CC − 0.6 V	V_CC − 0.1 V		V
V_OL	Low-level output voltage	I_OL = 1.6 mA			0.4	V
V_IT+	Positive-going input threshold voltage	V_CC = 3.3 V		1.6	2.4	V
V_IT+	Positive-going input threshold voltage	V_CC = 5 V		1.9	2.4	V
V_IT–	Negative-going input threshold voltage	V_CC = 3.3 V	0.6	1.1		V
V_IT–	Negative-going input threshold voltage	V_CC = 5 V	0.8	1.4		V
V_hys	Input hysteresis (V_IT+− V_IT–)			0.5		V
I_off	Output leakage current	FORCEOFF = 0 V		±0.05	±10	μA
r_i	Input resistance	V_I = ±3 V to ±25 V	3	5	7	kΩ

(1) All typical values are at V_CC = 3.3 V or V_CC = 5 V, and T_A = 25°C.

(2) Test conditions are C1−C4 = 0.1 μF at V_CC = 3.3 V ± 0.3 V; C1 = 0.047 μF, C2−C4 = 0.33 μF at V_CC = 5 V ± 0.5 V.
