24 Mbps bidirectional level translator with auto-direction sensing
The TXS0104EPWR: Its auto-direction sensing feature eliminates the need for a direction-control pin, simplifying board layout and firmware — the part automatically determines the data direction on each channel by sensing the drive state. The open-drain and push-pull output architecture supports both I2C-style open-drain buses and standard push-pull logic, though the 24 Mbps maximum data rate means it's best suited for slower serial interfaces like I2C, UART, SMBus, and general-purpose GPIO level shifting rather than high-speed SPI or SDIO. Packaged in a 14-TSSOP with a 0.173" body width, it's a surface-mount part that requires a controlled reflow profile — not a hand-solder-friendly SOIC, but manageable with practice and a fine tip.
For those, look at the CAXC4T774QBQBRQ1 which is AEC-Q100 qualified and rated to 125°C. The 14-TSSOP package has a 4.40 mm body width and 0.65 mm pitch; the exposed pad is not present, so thermal dissipation relies on the leads and copper pour.
If you're already using the TXS0104 in a design, the EPWR reel option is functionally identical — just a different shipping medium.
