In the following table, VDDIO means the VDDO power rail.

Table 42: TWSI Interface 3.3V DC Electrical Specifications

Parameter	Symbol	Test Condition	Min	Typ	Max	Units	Notes
Input low level	VIL		-0.5		0.3*VDDIO	V	-
Input high level	VIH		0.7*VDDIO		VDDIO+0.5	V	-
Output low level	VOL	IOL = 3 mA	-		0.4	V	-
Input leakage current	IIL	0 < VIN < VDDIO	-10		10	uA	1, 2
Pin capacitance	Cpin			5		pF	-

Notes:

General comment: See the Pin Description section for internal pullup/pulldow n.

1.While I/O is in High-Z.

2.This current does not include the current flow ing through the pullup/pulldow n resistor.
