3 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.
