Dear team,

As topic, may I know if SN74AUP1T50 can be used in 3.3V to 1.8V system? If yes, what is Vcc that we should use? Thank you.

Hi Polly,
No, the SN74AUP1T50 can't be used for a 3.3V to 1.8V down translation because it does not support a supply voltage of 1.8V. The supply of the device will determine its output voltage, so you must use 1.8V for the supply in this application.

A device that will work is the SN74AUP1G17.
