Description
The TXB0108 is a high-performance, 8-bit non-inverting voltage level translator designed to enable seamless communication between devices operating at different voltage domains. Featuring auto-direction sensing, this device eliminates the need for a separate direction control pin, simplifying complex bus-level shifting designs. With two independent, configurable power-supply rails, VCCA (1.2V to 3.6V) and VCCB (1.65V to 5.5V), it provides universal bidirectional translation for a vast range of logic nodes including 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V systems.
Built for reliability in demanding environments, the TXB0108 includes robust ESD protection up to ±15kV and an IOFF feature that supports partial power-down mode, preventing damaging back-flow current when the device is unpowered. Whether used in high-speed communication interfaces, consumer smartphones, or industrial PC peripherals, the TXB0108 delivers consistent performance with ultra-low power consumption. Its compact TSSOP-20 package is perfectly suited for modern, high-density PCB layouts.
Key Features
- 8-Bit Bidirectional Translation: Full 8-channel translation with automatic direction sensing for simplified interface design.
