Overview
The Texas Instruments TXU0104PWR is a four-channel unidirectional level shifter designed for high-speed communication applications. This device is part of the TXU0104 family and is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package). It operates as a 4-bit, dual-supply noninverting fixed direction voltage level translation device, allowing each port to operate from 1.1 V to 5.5 V. The TXU0104PWR is suitable for various applications requiring efficient and reliable voltage level translation, including industrial automation, robotics, automotive electronics, and telecommunications.
