General Description
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
5-pin and 6-pin SC70 packages, respectively.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
