USB FULL-SPEED SOURCE ELECTRICAL CHARACTERISTICS
(VCC = +2.4V to +3.6V, VSD = +2.4V to +3.6V, VIO = +1.5V to +3.6V, VTM = +2.91V to +3.4V, TA = -40°C to +85°C, unless otherwise
noted. Typical values are at VCC = +3.3V, VIO = +2.5V, VSD = +2.5V, VTM = +3.3V, TA = +25°C.) (Note 2)
Note 2: All parameters are tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 3: On-resistance is measured by applying voltage and current on the SD card interface (CCLK1, CCMD1, CDAT1_[3:0],
CCLK2, CCMD2, CDAT2_[3:0]).
Note 4: Off-capacitance measured with SD switch open (CCLK1, HCLK1, CCMD1, HCMD1, CDAT1_[3:0], HDAT1_[3:0], CCLK2,
HCLK2, CCMD2, HCMD2, CDAT2_[3:0], HDAT2_[3:0]).
Note 5: On-capacitance measured on SD card side (CCLK1, CCMD1, CDAT1_[3:0], CCLK2, CCMD2, CDAT2_[3:0]).
Note 6: Specifications guaranteed by design.
