I have a microcontroller which I need to run at 3.3V. But then i have another chip which wont work at 3.3v (works on 5v). What do i do if my microcontroller is sending signal to the other chip??
JUST USE TRANSITOR CKT AS A VOLTAGE FOLLOWER OR U CAN USE OPTO COUPLR, OR THERE R MANY INVRTER , NON INVERTER IC'S WHICH CAN BE USED FOR THIS PURPUOSE FOR EXAMPLE 75LS244

The transistor solution is only good if you need to translate 1 or 2 lines. Typically you will need two transistors per line (if the line in dual directional). If you need more lines (say for an LCD screen) then a line buffer IC is the preferred solution.
