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 VCCfrom +2.5V to +5.5V and VLfrom +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 VCCside to the VLside and from the VLside to the VCCside. 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.ApplicationsCell Phone CradlesCell Phone Hands-Free KitsLow-Voltage ASIC Level TranslationPortable Communication DevicesPortable POS SystemsRS-232-Compatible TranslationSmart Card ReadersSPI™, MICROWIRE™, and I²C Level Translation
