Part Number: TS5A2066
I use TS5A2066, but it’s VDD is 5V and control signal is 3.3V for logic high. As the datasheet shows, when VDD is 5V, the digital control signal need to be higher than 5V*0.7=3.5V.
So my question is if I continue to use 3.3V for control signal, can TS5A2066 work properly?
As the datasheet mentions, when VDD is 5V, the digital control signal need to be higher than 5V*0.7=3.5V to be considered as logic high.
The VIH and VIL specs are the guaranteed input HIGH or input LOW levels.
For an input signal at 5V operation, from 0V to 1.5V, the TS5A2066 sees this signal as a LOW. From 1.5V to 3.5V the input is UNDEFINED, and from 3.5V to 5V, the input is HIGH.
The undefined state can lead to high Icc (shoot-through) current and device damage.
In 1:1, 2 channel configuration, you can look at our new TMUX1121, that supports wider control input range for VIH , and has lower Ron compared to TS5A2066.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
