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.
