The Texas Instruments TXS0104EGXUR is a 4-channel bidirectional voltage-level translator designed for open-drain and push-pull applications. The auto-direction sensing feature eliminates the need for a direction-control signal, simplifying both PCB layout and firmware — the translator automatically determines data flow on each channel. Typical applications include I2C, SMBus, SPI, and UART level shifting in industrial sensors, portable electronics, and telecom line cards. With a 24 Mbps data rate it handles most serial buses comfortably, though it is not rated for high-speed parallel interfaces.
Package and temperature — board-fit notes
The TXS0104EGXUR comes in a 12-BGA Microstar Junior package (2 mm × 2.5 mm ball array). This is a fine-pitch BGA — rework and visual inspection require X-ray or a microscope, so factor that into your assembly yield and field-repair plan.
Lifecycle reality — this part is obsolete
That means TI has stopped manufacturing it, and no last-time-buy window remains open. Stock is finite and depleting — if your BOM requires this exact order code, the window to secure inventory is closing.
Sourcing posture for the BOM line
Because the TXS0104EGXUR is obsolete, it is a single-source risk for any production run. For existing BOM lines already using this code, we can source it through independent channels against an RFQ. Lead times and pricing vary with market availability; we provide a firm quote with each inquiry. No minimum order quantity is required for a quote.
