Overview
The TMUX154EDGSR, produced by Texas Instruments, is a high-bandwidth, 2-channel, 2:1 switch designed for the switching and isolating of high-speed signals in systems with limited I/Os. This device is particularly useful in applications where signal integrity and minimal distortion are crucial. The TMUX154E features a wide bandwidth of 900 MHz, allowing signals to pass with minimal edge and phase distortion. It is bidirectional, offering little or no attenuation of high-speed signals, and is designed for low bit-to-bit skew and high channel-to-channel noise isolation. The device integrates ESD protection cells on all pins and is available in both VSSOP and UQFN packages, characterized over a temperature range of –40°C to 85°C.
