MAX3370, MAX3371 低電壓電平轉(zhuǎn)換器,SC70和μDFN封裝(含應(yīng)用電路)
概述
The MAX3370/MAX3371 logic-level translators are ideal for applications interfacing low-voltage devices to other logic levels. Externally applied voltages set the logic levels of the MAX3370/MAX3371. The devices accept VCC from +2.5V to +5.5V and VL from +1.6V to +5.5V, allowing data transfer between low-voltage ASICs and higher voltage devices. The MAX3371 features a shutdown mode that reduces supply current to < 1μA and puts the I/O pins in a high-impedance state.
The MAX3370/MAX3371 are bidirectional level shifters, allowing data transfer from the VCC side to the VL side and from the VL side to the VCC side. Both devices operate at speeds up to 2Mbps with an active driver and up to 500kbps with an open-drain driver.
The MAX3370/MAX3371 are available in space-saving μDFN (1mm x 1.5mm) and SC70 packages.
