hi
i am using controller(operating voltage 3.6V).i want to connect serial LCD(voltage level 5V) to the UART of controller. so basically i need CMOS level to TTL level converter. am i correct?and also give me some CMOS to TTL level coverter ic names.
TTL compatible inputs are fine with 3.6V (> 2.4) logic level, so you don't need a converter. You may want to check the LCD datsheet, if it actually has a TTL level specification.
