Product details

100 Mbps bidirectional level shifting with auto-direction sensing

Its auto-direction sensing feature eliminates the need for a direction-control pin, which simplifies firmware and saves a GPIO on the controller side. Outputs are tri-state and non-inverted, with all channels bidirectional in a single 14-TSSOP package.

Industrial temperature range and active lifecycle

The lifecycle status is Active, so there is no looming end-of-life risk for production builds or new designs. The G4 suffix on the order code indicates a lead-free, RoHS-compliant finish — electrically identical to the base TXB0104PWR, just a different plating option.

14-TSSOP footprint and supply routing

Surface-mount assembly is standard. The auto-direction sensing handles the data flow automatically; just connect the rails and signals.

Frequently asked questions

What is the difference between TXB0104PWRG4 and TXB0104PWR?

The G4 suffix indicates a lead-free, RoHS-compliant plating finish. Electrically and functionally the two are identical — same 100 Mbps data rate, same dual-supply range, same auto-direction sensing, same 14-TSSOP package. The G4 variant is the greener option for RoHS-driven BOMs.

Can TXB0104PWRG4 be used for level shifting between 1.8V and 3.3V?

Yes. Set VCCA to 1.8 V (within its 1.2 V–3.6 V range) and VCCB to 3.3 V (within its 1.65 V–5.5 V range). The auto-direction sensing handles bidirectional data flow at up to 100 Mbps without any direction pin.

Is TXB0104PWRG4 bidirectional?

Yes, all four channels are bidirectional, with auto-direction sensing that determines the data flow direction without an external control signal.

What is the data rate of TXB0104PWRG4?

The TXB0104PWRG4 supports data rates up to 100 Mbps, suitable for high-speed protocols like SPI and JTAG.
