Overview
The TXU0304RUTR, produced by Texas Instruments, is a 4-bit, dual-supply noninverting fixed direction voltage level translator. This device is part of the TXU0304 family and is designed to facilitate voltage level translation between two different voltage domains. It features a fully configurable dual-rail design, allowing each port to operate from 1.1 V to 5.5 V, making it versatile for various applications. The device supports high-speed data transmission up to 200 Mbps for 3.3 V to 5.0 V translations and includes Schmitt-trigger inputs to handle slow or noisy input signals.
