The auto-direction sensing eliminates the need for a direction-control pin, so the part is a drop-in for open-drain and push-pull interfaces where the bus direction changes dynamically — think I²C, MDIO, or a UART TX/RX pair. The 100 Mbps rating means it handles SPI at 50 MHz or a parallel bus running at moderate clock rates without adding a cycle of latency. ## Supply rails and temperature range VCCB accepts 1.65 V to 5.5 V. The part does not require a specific power-up sequence — either rail can come up first — but the output state during power-up is undefined until both supplies are within tolerance. For BOM planning, this removes the risk of a last-time-buy window closing unexpectedly.","metaTitle":"Texas Instruments TXB0104DRG4 Voltage Level Translator","metaDescription":"Texas Instruments TXB0104DRG4 bidirectional voltage-level translator. 100 Mbps data rate, auto-direction sensing, 1.2 V to 5.5 V supply range.
