3 Description

The TMUX154E is a high-bandwidth 2:1 switch

specially designed for the switching of high-speed

signals in applications with limited I/Os. The wide

bandwidth (900 MHz) of this switch allows signals to

pass with minimum edge and phase distortion. The

switch is bidirectional and offers little or no

attenuation of high-speed signals. It is designed for

low bit-to-bit skew and high channel-to-channel noise

isolation.

The TMUX154E integrates ESD protection cells on all

pins, is available in a tiny UQFN package (1.8 mm ×

1.4 mm) or a VSSOP package, and is characterized

over the free-air temperature range of –40°C to 85°C.
