1µA, 2Mbps, Low-Voltage Level
Translators in SC70 and µDFN
The MAX3370/MAX3371 provide the necessary level
translation to allow data transfer in a multivoltage sys-
tem. These devices transmit data between an I/O pin
referenced to V
V
the V
+5.5V. The MAX3371 features a shutdown mode in
which I/O V
ance state and supply current drops to 1µA.
The MAX3370/MAX3371 are bidirectional level shifters
allowing data transfer from the V
and from the V
operate at speeds up to 2Mbps with an active driver
and up to 500kbps with an open-drain driver.
The MAX3370/MAX3371 provide bidirectional level
translation between I/O pins referred to V

be between +1.6V and +5.5V. For proper operation, V
can not exceed V
The MAX3370/MAX3371 can operate at data rates up
to 2Mbps when driven by an active (push-pull) driver
with a 10pF load, 1Mbps when driven by an active dri-
ver with a 50pF load, or 500kbps when driven by an
open-drain driver with a 30pF load. The internal pullups
allow these devices to be driven by open-drain drivers.

The MAX3371 enters a low-power shutdown mode
when SHDN is driven low. Connect SHDN to V
high for normal operation. Activating shutdown mode
disconnects the internal 10kΩ pullup resistors on I/O

decreases to < 1µA, and the I/O lines are high imped-
