Overview
The TXU0204PWR, produced by Texas Instruments, is a 4-bit, dual-supply noninverting fixed direction voltage level translation device. This component is designed to facilitate voltage level translation between two different voltage domains, making it highly versatile for various electronic systems. The device supports input voltages ranging from 1.1 V to 5.5 V on both A and B ports, allowing for flexible integration into different system architectures. The TXU0204PWR features a fully configurable dual-rail design and supports high-speed data transmission up to 200 Mbps for certain voltage ranges.
