Simple Logic-Level Translation Interfaces 1.8V Microcontrollers and 3V Peripherals

资料介绍
Interfacing a 1.8V microcontroller to a 3V peripheral poses a design challenge, because the logic output of the microcontroller cannot satisfy the peripheral's VIH and VIL requirements. A logic-level translator needs to be used to interface the two devices. The interface circuit can consist of a simple resistor and diode or an integrated logic-level translator.
