Description

The TMUXHS221 is a high-speed bidirectional 2:1/1:2 multiplexer/demultiplexer optimized for USB 2.0 and eUSB2 LS, FS, and HS signaling. The TMUXHS221 is an analog passive switch that works for many high-speed interfaces for data rates up to 3 Gbps. The TMUXHS221 supports either differential or single ended CMOS signaling with a voltage range of −0.3 to 3.6 V. The excellent high speed performance of the TMUXHS221 results in minimal attenuation to the USB 2.0 or eUSB2 HS signal eye diagrams with very low channel ON resistance, high bandwidth, low reflection, and low added jitter. The device is optimized for excellent high frequency response so that passing USB 2.0 HS electrical compliance becomes easier. The datapaths of the device are also matched for best intra-pair skew performance. The TMUXHS221 has an extended temperature range that suits many rugged applications including industrial and high reliability use cases. .
