1µA, 2Mbps, Low-Voltage Level
Translators in SC70 and µDFN
MAX370
General Description
Features
♦ Allow Bidirectional Level Translation
♦ Miniature µDFN (1mm x 1.5mm) and SC70
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
Packages
♦ Operational Down to 1.6V
♦ Low Quiescent Current (< 100µA)
V
from +2.5V to +5.5V and V from +1.6V to +5.5V,
L
CC
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.
♦ Ultra-Low (< 1µA) Shutdown Supply Current
/MAX371
(MAX3371)
♦ Three-State Outputs in Shutdown (MAX3371)
♦ 2Mbps (10pF Load) Push-Pull Driving
♦ 1Mbps (50pF Load) Push-Pull Driving
♦ 500kbps (30pF Load) Open-Drain Driving
The MAX3370/MAX3371 are bidirectional level shifters,
allowing data transfer from the V
side to the V side
L
CC
and from the V side to the V
side. Both devices
CC
L
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.
