Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
The control pins have fail-safe logic, the I/O pins have not. There are clamping diodes to V DD , so a current can flow from the I/O pins into the supply.
In general, CMOS switches have low leakage currents, so you should just leave them powered.

The TCA9548A-Q1 is the only automotive-qualified I²C switch.
You could use a general-purpose switch like the TS3A5017-Q1, but it would require GPIOs to control it.
Part Number: LDC1101 Other Parts Discussed in Thread: TIDA-01102 , , TS3A5017 , LDC1614 I am considering a design with four LDC1101 chips. I know that the LDC1614 is a quad version with LHR measurement, however, the LDC1101 has LHR and Rp+L modes. A reference…
Other Parts Discussed in Thread: TS3A5017 Hi,
My application requires precision to measure RTD (Resistance Temperature Detector) of 100 ohms +/- 0.1%. I use the analog switch TS3A5017 in series with the signal paths of a dual 0.5 mA current sources to measure…
Other Parts Discussed in Thread: TS3A5017 Hi,
Does TS3A5017 can switch on/off analog audio (mono) and UART and GPIO(HI/LO) on the same chip.
for example:
1S1 and 2S1 is for mono analog audio.
1S2 and 2S2 is for UART(TX and RX, Baud rate is 115200bps )
1S3…
Part Number: TMUX1309-Q1 Other Parts Discussed in Thread: TS5A23157-Q1 , TS3A5017-Q1 , SN3257-Q1 hi TI,
Question 1: Can TMUX1309-Q1 be used to switch LVDS signals?
Question2：I don't understand why the on resistance is so large, as shown in the figure below…
Other Parts Discussed in Thread: TS5A23157 , TS3A5017 We are using TS3A5017RSV part in our design and are testing it for the temperatures up to +105 degree. The part is working absolutely fine. This part is not qualified for this temperature range but its…
Part Number: TS5A3357 Other Parts Discussed in Thread: TS3A5017 , TS3A5017, TS5A3357, these 2 mux will support I2C is 3.4MHz, SPI is 20MHz, UART is 1MBaud speed?
These restriction are needed because active buffers must be able to detect in which direction the signals flow.
Passive switches/muxes like the TCA9548A-Q1 do not have this problem.
It might be also be possible to use plain analog switches/muxes like…
Part Number: SN74CBTLV3257 Other Parts Discussed in Thread: SN74CBTLV3253 , , TMUX1309 , TS3A5017-Q1 , TMUX1574 Hi,
my customer is using SN74CBTLV3257 and SN74CBTLV3253, but now they need extend the operating temperature to 105C.
What's the best pin to pin…
