TS3A27518E: IN1/IN2 open

Kurumi Hasegawa

Part Number: TS3A27518E

Hi team,

I know the IN1/IN2 supposed to be held at H or L. But could you tell expected behavior of the switches if IN1/IN2 was left open?

The expected behaviour is for increased power consumption, for some random switch state, for the switches to oscillate, or for the device to get damaged. See [FAQ] How does a slow or floating input affect a CMOS device?

Hi Kurumi,

Clemens is correct, having floating IN1/IN2 control pins will cause an undefined logic value which can lead to increased power consumption, possible oscillations can occur, and ultimately device damage. Also the switches connected to IN1/IN2 would not be controllable and would be in an undefined state (it could potentially pass signals, but with negative impacts to signal integrity)

If you have any other questions please let me know!

Best,

Parker Dodson
