1碌A, 2Mbps, Low-Voltage Level
Translators in SC70
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
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 shut-
down mode that reduces supply current to <1碌A 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 V
L
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
5-pin and 6-pin SC70 packages, respectively.
