The TXB0104RUTR from Texas Instruments is a 4-bit non-inverting bidirectional voltage-level translator featuring automatic direction sensing. Its dual-supply architecture enables bidirectional logic-level translation without requiring a dedicated direction-control signal, while supporting data rates of up to 100Mbps.
The A-side supply, VCCA, operates from 1.2V to 3.6V, while the B-side supply, VCCB, operates from 1.65V to 5.5V, with VCCA required to be equal to or lower than VCCB. This enables translation between common 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V logic domains.
The TXB0104 uses a push-pull architecture with integrated edge-rate accelerators to improve signal transition performance. An Output Enable input places all outputs into a high-impedance state when disabled. The device also supports Ioff partial-power-down operation and VCC isolation to help prevent damaging current backflow when a supply rail is powered down.
The B port provides up to ±15kV HBM ESD protection. The TXB0104RUTR is supplied in a compact 12-pin UQFN (RUT) package measuring approximately 2.0 × 1.7mm and operates from -40°C to +85°C. Typical applications include GPIO, SPI, UART, I²S, JTAG and PCM interfaces.
