3 Description

The TMUXHS221LV is a high-speed bidirectional

2:1 or 1:2 multiplexer or demultiplexer optimized for

USB 2.0 and eUSB2 LS, FS, and HS signaling.

The TMUXHS221LV is an analog passive switch that

works for many high-speed interfaces with data rates

up to 3Gbps. The TMUXHS221LV supports either

differential or single-ended CMOS signaling with a

voltage range of ?0.3 to 3.6 V.

The ideal high-speed performance of the

TMUXHS221LV 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 ideal high frequency response so that

passing USB 2.0 HS electrical compliance becomes

easier. The data-paths of the device are also matched

for best intra-pair skew performance.

The TMUXHS221LV has an extended temperature

range that suits many rugged applications including

industrial and high reliability use cases.
