Description
The TXB0104D is a high-performance, 4-bit non-inverting voltage level translator designed for seamless communication between devices operating at different voltage domains. Utilizing two separate, configurable power-supply rails (VCCA and VCCB), this device facilitates universal, bidirectional voltage translation. The A-port tracks VCCA (1.2V to 3.6V), while the B-port tracks VCCB (1.65V to 5.5V), enabling compatibility across a wide variety of logic levels including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V systems.
Equipped with an Output Enable (OE) pin, the device allows for high-impedance control, making it ideal for bus-sharing applications. Furthermore, the TXB0104D includes advanced IOFF circuitry, which prevents damaging back-flow current during partial power-down scenarios, ensuring superior reliability in power-sensitive designs. Its compact SOIC-14 package makes it an excellent choice for space-constrained applications like portable electronics and communication interfaces.
