Abstract
This utility model discloses an interface circuit, including: a power supply unit, a first buffer unit, a level converter, and a second buffer unit. The power supply unit is connected to a power supply voltage and the first buffer unit to generate a power supply voltage for powering the first buffer unit based on the power supply voltage. The power supply voltage is connected to the second buffer unit to power the second buffer unit. The level converter is connected to the output terminal of the first buffer unit and the input terminal of the second buffer unit to perform level conversion between the first and second buffer units. According to the interface circuit of this utility model, a simple design is adopted to meet the power supply requirements with a single power supply, saving chip area and power consumption, and achieving a combination of low cost and high efficiency.
