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.
