VCCA, VCCB0, and VCCB1 Each Operate Over Full C 1500-V Charged-Device Model (C101) 1.1-V to 3.6-V Range ? ±8-kV Contact Discharge IEC 61000-4-2 ESD Performance (B Port) DESCRIPTION/ORDERING INFORMATION The TXS02612 is designed to interface the cell phone baseband with external SDIO peripherals. The device includes a 6-channel SPDT switch with voltage-level translation capability. This allows a single SDIO port to be interfaced with two SDIO peripherals. The TXS02612 has three separate supply rails that operate over the full range of 1.1 V to 3.6 V. This allows the baseband and SDIO peripherals to operate at different supply voltages if required. The select (SEL) input is used to choose between the B0 port and B1 port. When SEL = Low, B0 port is selected;
when SEL = High, B1 port is selected. SEL is referenced to VCCA. For the unselected B port, the clock output is held low, whereas the data and command I/Os are pulled high to their respective VCCB through a 70-k? resistor (±30% tolerance).

2009 www.ti.com SIMPLIFIED INTERNAL STRUCTURE A. R1 and R2 resistor values are determined based upon the logic level applied to the A port or B port, as follows: R1 and R2 =
40 k? when a logic level low is applied to the A port or B port. R1 and R2 =
4 k? when a logic level high is applied to the A port or B port. R1 and R2 =
70 k? when the port is deselected.
