Key Technical Specifications

• Function: 6-Channel SPDT (Single-Pole Double-Throw) Multiplexer/Demultiplexer.[4]
• Voltage Range: 1.1V to 3.6V (Supports independent rails for host and both peripherals).[4][6][7][8]
• Interface Support: SD, SDIO, and MMC (MultiMediaCard).[4]
• Operating Frequency: Up to 60 MHz.[4]
• Supply Rails:
  • VCCA: Host-side supply (1.1V to 3.6V).
  • VCCB0 & VCCB1: Peripheral-side supplies (1.1V to 3.6V).
• Package: 24-pin WQFN (4mm x 4mm).[2][9]
• Operating Temperature: -40°C to +85°C (Industrial Grade).
• ESD Protection:
  • A-Port: 2 kV Human Body Model (HBM).
  • B-Ports: ±8 kV IEC 61000-4-2 Contact Discharge.[1][2][7][8]

Core Functionality

The chip acts as a "traffic controller" for data signals (Clock, Command, and 4 Data lines).

1. Expansion: It splits one SDIO port into two (Port B0 and Port B1).
2. Selection: A single SEL pin determines which peripheral is active.[7][8]

• SEL = Low: Port B0 is connected to the Host.
• SEL = High: Port B1 is connected to the Host.

Translation: It automatically translates logic levels between the host and peripherals. For example, if your processor runs at 1.8V but your SD card requires 3.3V, the TXS02612 handles the voltage shift without needing external direction-control signals.
