SDHC Card series

4~32GB High Capacity Secure Digital Card

•Bus Signal Levels

As the bus can be supplied with a variable supply voltage, all signal levels are related to the supply voltage.

To meet the requirements of the JEDEC specification JESD8-1A and JESD8-7, the card input and output voltages shall be within the following specified ranges for any VDD of the allowed voltage range:

Parameter	Symbol	Min.	Max.	Unit	Remark
Output HIGH voltage	VOH	0.75* VDD		V	IOH = -100 μA @VDD min
Output LOW voltage	VOL		0.125* VDD	V	IOL = -100 μA @VDD min
Input HIGH voltage	VIH	0.625* VDD	VDD + 0.3	V
Input LOW voltage	VIL	VSS – 0.3	0.25* VDD	V
