TMUXHS4446RETR TI Multiplexer Switch IC | 40-WQFN (6x3) | 4-Channel, 2:1, 10Gbps

Product Overview

The TMUXHS4446RETR from Texas Instruments is a high-performance 4-channel, 2:1 multiplexer/demultiplexer switch designed for high-speed signal routing. It supports data rates up to 10 Gbps per channel, making it ideal for USB 3.1 Gen 2, DisplayPort 1.4, and PCIe Gen 3 applications. The device operates over a wide supply voltage range of 1.8V to 3.3V and features low ON-state capacitance (3.5 pF typical) and low ON-state resistance (5 Ω typical). Housed in a compact 40-pin WQFN (6x3 mm) package, it offers excellent signal integrity with minimal crosstalk and insertion loss.
