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, 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 V
OH
