Introduction
TI switches and multiplexers are often designed using one of three different circuit architectures that enable different characteristics and capabilities depending on which one is selected. The typical architectures can be broken down into…
Other Parts Discussed in Thread: SN74CB3Q3345 While all TI switches and multiplexers incorporate some type of ESD protection, the way they are implemented can differ significantly. The typical implementation can be seen below (simplified model):
In this…
TI devices typically have a code printed or etched on their top side that contains information about what device it is, when it was manufactured, and where it was manufactured. This code is referred to by a few names such as top marking, top side marking…
Some TI switches and multiplexers have orderable part numbers labelled with an E4/G4/G3 suffix. There is no difference between a device labeled with an E4/G4/G3 suffix and one without the label. TI.com highlights this in the ordering & quality section…
Other Parts Discussed in Thread: TMUX646 When looking for an analog switch / multiplexer for LVDS (Low-Voltage Differential Signaling) applications, it is import to understand the specifications of the LVDS standard (TIA/EIA-644):

A very common, but very powerful use of a multiplexer is for applications in which there is a need for more GPIO pins for expanded functionality…
Other Parts Discussed in Thread: TMUX1574 , TMUX1575 , TS3A27518E , TMUX646 TI signal switches and multiplexers can be used for JTAG (Joint Test Action Group) applications, but a few things need to be considered before selecting a device. The most important…
It is not always necessary to use every pin that may be present on a TI signal switch or multiplexer, but what to do with the unused pins can often cause some confusion. In this FAQ, we will explore all the possible scenarios for each type of pin and…
