Can SN743306 only do Switch function?

The input is 5V level, and the output is also 5V level.

This device outputs 3.3 V.

Use the SN74LVC2G66 instead.

Hey Su,

The SN74CBTD3306 won't get you to 5V at the output.
If you're looking for simply switching a 5V signal, the SN74LVC2G66 is a good choice. If you're looking for a device that will redrive the 5V signal, then you'll want to look for a buffer instead.

Thanks,
Rami
