I have a simple question about ADG3241, level shift IC.
I want the levelshift from 3.3V to 1.8V/2.5V.
I checked out the datasheet, but I'm not sure if 3.3V logic input /output should be connected to A pin or Bpin.
Please give me answer on that.
The ADG3241 is bidirectional; you can place the 3.3V on either A or B.
The signal can only be translated down, so a 3.3V signal will saturate at either 2.5V/1.8V, while a 2.5V or 1.8V signal will remain 2.5V or 1.8V respectively.
Thank you for your support.
I understand it.
Let me ask you one more thing.
About ADG3242,two channle of ADG3241,
please tell me how to handle unused pins when using only one channle.
Please check the detail on the attached file.
Typically, connecting them to a known voltage is recommended and I suggest GND.
Thanks for your prompt reply.
I will connect unused pins to GND.
Thanks for your support.
