￿Input Characteristics for UDMA mode >4

In UDMA modes greater than 4, the following characteristics apply. Voltage output high and low values shall be met at the source connector to include the effect of series termination.

Table: Input Characteristics (UDMA Mode > 4)
Parameter	Symbol	MIN	MAX	Units
DC supply voltage to drivers	VDD3	3.3 –8%	3.3% + 8%	Volts
Low to high input threshold	V+	1.5	2.0	Volts
High to low input threshold	V-	1.0	1.5	Volts
Difference between input thresholds:	VHYS	320		Volts
((V+ current value) - (V-current value))
Average of thresholds:	VTHRAVG	1.3	1.7	Volts
((V+ current value) + (V-current value))/2

￿Output Drive Characteristics for UDMA mode > 4

In UDMA modes greater than 4, the characteristics specified in the following table apply. Voltage output high and low values shall be met at the source connector to include the effect of series termination.

Notes:
1)	IoLDASP shall be 12 mA minimum to meet legacy timing and signal integrity.
2)	IoH value at 400 A is insufficient in the case of DMARQ that is pulled low by a 5.6 k resistor.
3)		μ		Ω
	Voltage output high and low values shall be met at the source connector to include the effect of series termination.
4) A device shall have less than 64			A of leakage current into a 6.2 K pull-down resistor while the INTRQ signal is in the released
	state.		Ω
