Hi,
I am using a microcontroller working on 5V, which is directly connected to a sensor working on 3.3v for data communication(recieve and transmit at 38.kkbps). Even though the sensor is 5V tolerant, I ought to provide a protection circuitry because the sensor fails randomly. May be the Vcc goes to 5.5V.
Can somebody give an idea about how to connect a mixed 3.3v and 5V different systems? Is there any IC available for level shifting from 5V to 3.3V?
Thanks
Jaison
