MAX3370, MAX3371 低电压电平转换器，SC70

MAX3370, MAX3371 低电压电平转换器，SC70和µDFN封装(含应用电路)

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 V_CC from +2.5V to +5.5V and V_L 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 V_CC side to the VL side and from the V_L side to the V_CC 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.
