Hi team,
My customer is using SN74CBTLV3253 and have some spec question to ask,
so quick check on the spec question of SN74CBTLV3253,
1. This device internally using FET as switch(“SW”)
2. this device can use as Multiplexer/Demultiplexer , means the signal can transfer bi-directional.
do let me know if above assumption is not right , thanks a lot!
Andy
Hi Andy,
Thanks so much for your question. You are correct with both of these assumptions.
All of TI's analog switches and multiplexers are passive switches, meaning the internal structure is a FET switch or transmission gate switch (two FETs in parallel).
Second, because of this internal structure, all of TI's analog switches and multiplexers are bidirectional (multiplexer/demultiplexer).
Check out these two videos to learn more:
Are switches and multiplexers bidirectional?
What are common switch architectures?
Additionally, I would like to point out that we have a great new device, TMUX1209, that may be suited for your customer's application. What is the application, end equipment, and specifications needed for this device? TMUX1209 supports 1.8V logic levels, break-before-make, and fail-safe logic. Check out the comparison below and let me know what you think.
Regards,
Kate
