TS5A3357-Q1: COM output not as expected in the TS5A3357-Q1

Edson Manoel da Silva

Part Number: TS5A3357-Q1

Hi,

I am trying to test the TS5A3357-Q1 but I am having some problems. Basically what I am trying to do is the following:

If I set IN1 =1 and IN2=0 I get 3.3V in the COM pin as expected. However, If I set IN1 = 1 and IN2=1 I get 2V in the COM pin instead of 0V. Plus, If I set IN2=0 and IN1=1 I get 2.5V in the COM pin instead of 0V.

What am I doing wrong?

Thanks!

Edson,

You are following the truth table correctly and 3.3 V is within the recommended operating condition.

What is connected to NO1/2/3? How do you know those voltages? Is it possible those voltages are not what you expect and are propagating to COM pin?

What is the voltage on the IN pins? Is it possible they are not at 0V or Vcc which is partially turning on and off the switch?

Have you removed the device and checked the voltages?

Does replacing it solve the issue?

Thank you,
Adam

Edson,

I haven't heard from you in a while so I will assume you have solved your issue. I will close this thread but you may reply here to reopen it if you have additional questions.

Thank you,
Adam
