MAX3371ELT-T

1µA, 2Mbps, Low-Voltage Level Translators in SC70 and µDFN

Maxim Integrated 

19-1847; Rev 3; 5/09

1µA, 2Mbps, Low-Voltage Level

Translators in SC70 and µDFN

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

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 shut-

down 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.
