Part Number: TMUX4821 Hi TI, It is assumed that the output of the FPGA is connected to the VDD and TMUX4821 is driven. When the load connected to Dx and Sx fluctuates, how does the TMUX4821 power supply current behave? Does the power supply current of…
Part Number: TMUX4821 Other Parts Discussed in Thread: TMUX4827 , Hi, team
I would like to control the VDD and SEL of the TMUX4827 with the same signal. Please let me know the answers to the following questions.
Q1. Does the TMUX4821 have an internal…

Part Number: TMUX6236 Other Parts Discussed in Thread: TMUX7436F , TMUX4827 , TMUX4819 , TMUX4821 Hi Team,
Can TMUX6236 survive a short to battery on the switch inputs, source to drain, when VDD isn't present?
Source signals come from a wiring harness…

Hello Jerome,
What voltage level will the mux see on its I/Os when its unpowered? You might need to use a different mux like the TMUX4821 which was designed for current loops and has powered off protection.
Thanks,

Hello Shaohui,
I see thank you for clarifying, but those are max specs. They are there to provide additional head room. I believe in practice the Ron difference will be much less.
For Ron drift across temp I recommend looking at the actual graphs…
