You can use an analog switch in your application.
You can use the TS5A63157 SPDT to select between VBAT and GND. Let me know what you think of this switch - I can help you select another if you would like.
Many of the analog switches require VCC before…
Hi Ritesh,
1, For 24.576MHz clock generator, could you consider LMH1983 in your system? It is a powerful device.
2, For multiplier for 3.072MHz & zero-delay buffer, TI has X4 device CDCVF25084. It is 1:8 zero-delay buffer. That's easy to get divider…
Hi Atsushi,
The automotive device datasheet is the one that you should follow. That being said this device could back power the VDD rail since Vin > VDD + 0.5V when VDD = 0V. The IC itself won't be damaged by the ~26uA current but it will back-power…
Hi Ben,
Yes there is risk when using the TMUX1219 in this way.
When VDD is under operational voltage the switch states are undefined - so there is no isolation guaranteed when operating the IC in this way.
The other issue is that this device…
Hi,
thanks for you support.
We just defined the power supply of the entire signal chain and "unfortunately" it is 5.0V.
Nevertheless on the datasheet of the TS3USB31E the Vcc Absolute maximum rating is 7V and the "recommended conditions are 4.3V max…
Hello Adam,
Thank you for your detailed response, which is much appreciated. I like the OFF-state leakage current column in this parametric table - would it be possible to also introduce such a column in your other selection tables, e.g. in this case…

BTW: High-Z is the default state of almost all MSP GPIO pins. In this state, there is only a small leakage current of up to 50nA. And no need to reconfigure them at all.
However, input pins in high-Z state will have significant…
