Texas Instruments (TI) Switches & multiplexers support forum is an extensive online knowledge base where millions of technical questions and solutions are available 24/7. You can search switches & multiplexers IC content or ask technical support questions on everything from analog and protocol-specific switches/multiplexers (muxes) to power switches, encoders and decoders. Find the right solution for your circuit design challenges by using our TI E2E™ support forums that are supported by thousands of contributing TI experts.
When trying to find a multiplexer as a solution for RS-232, RS-422, and RS-485 applications. It is important to understand what parameters to look for when trying to find the right mux. Each protocol has its own requirements, but in order to make it simple…
When looking for a multiplexer to be implemented for hot-insertion (also known as hot-swapping) applications. It is important to make sure it has Ioff Circuitry and the Partial Power Down Mode feature. We also recommend to pick a multiplexer with a continuous…
Part Number: TMUXS7614D
Tool/software:
Most multiplexers use GPIO signals to switch between input and output connections. Another method of controlling a multiplexer is by using SPI. In place of GPIO control pins, a device controlled with SPI will…
Part Number: TMUX1574
Tool/software:
Shoot-through current occurs when CMOS inputs are somewhere between their High and Low voltages, effectively turning on both MOSFETs in the CMOS structure. In many devices, including analog multiplexers, this creates…

Hi Experts, '
Is there any guidelines to follow regarding the input when the TMUX is not powered.
Can i apply input voltage when the supply is not available.
Thank you for the guidance.
Regards,

S-parameter (or scatter parameter) models are AC based models used to understand small scale AC performance of devices. They are created by measuring the scattering (reflections and transmissions) of a device based on some stimulus…
What is Latch up?
Latch-Up is a condition where a low impedance path is created between a supply pin and ground. This condition is caused by a trigger (current injection or overvoltage), but once activated, the low impedance path remains even after…
One of the features our devices have is beyond the supply. It allows them to pass a voltage signal below ground or above VDD.
There are three different types of beyond the supply operations:
Negative signal operation
Positive signal operation…
When choosing an I2C switch , you might be curious as to why a PCA family switch has a TCA counterpart and vice versa.
The differences are the following:
1) TCA devices typically have lower supply voltage thresholds
2) TCA devices have corrected…
