TAP Electrical Characteristics

Over the Operating Range[10, 11, 12]

Parameter	Description	Test Conditions	Min	Max	Unit
VOH1	Output HIGH Voltage	IOH = −2.0 mA	1.4		V
VOH2	Output HIGH Voltage	IOH = −100 μA	1.6		V
VOL1	Output LOW Voltage	IOL = 2.0 mA		0.4	V
VOL2	Output LOW Voltage	IOL = 100 μA		0.2	V
VIH	Input HIGH Voltage		0.65VDD	VDD + 0.3	V
VIL	Input LOW Voltage		–0.3	0.35VDD	V
IX	Input and Output Load Current	GND ≤ VI ≤ VDD	–5	5	μA

Notes

10.These characteristics pertain to the TAP inputs (TMS, TCK, TDI and TDO). Parallel load levels are specified in the Electrical Characteristics Table.

11.Overshoot: VIH(AC) < VDDQ + 0.85V (Pulse width less than tCYC/2), Undershoot: VIL(AC) > −1.5V (Pulse width less than tCYC/2).

12.All Voltage referenced to Ground.
