MAX4784EUE+

Product Number: MAX4784EUE+, MAX4784

Hello,

I have a quick question on the logic inputs of the MAX4784EUE+. Can digital signals with High-Signal at 3.3V (at which level my microcontroller supplies) be used as logic signals? Thanks a lot!

Best greetings

Hi Franz100,

You can apply 3.3V to the /EN and A pins of the device - in this case the switch o/p is in high impedance.

The switch o/p is enabled if the /EN pin receives logic low signal.

Regards,

Thank you very much for the answer! Sorry, I needed to be more specific, if I enable the IC and use for the A-pin a digital signal with 3.3V level, does this work?
