• Manufacturer Part Number: MAX3371
• Description: 1uA, 2Mbps, Low-Voltage Level Translators in SC70
• Manufacturer: MAXIM [Maxim Integrated Products]

To reduce ripple and the chance of transmitting incor-
rect data, decouple V
capacitor as close to the device as possible.
The MAX3370/MAX3371 are ideal for level translation
between a low-voltage ASIC and an I
devices’ bidirectional natures allow their use in the data
line of I
interfacing a low-voltage microprocessor to a 3V or 5V
D/A converter, such as the MAX517.
The I/O lines on the MAX3370/MAX3371 are bidirec-
tional, can be level-shifted up to +5.5V, and contain
internal 10k
ving (see the Typical Operating Circuit).

The MAX3370/MAX3371 I/O pins can be driven by a
push-pull or open-drain device. When using a push-pull
driver, the MAX3370/MAX3371 operate up to 2Mbps
with a 10pF load or 1Mbps with a 50pF load. The inter-
nal pullup resistors on the I/O pins allow use with open-
drain devices. The MAX3370/MAX3371 operate up to
500kbps with a 30pF load when driven by an open-
drain device.
Data rates higher than those listed in the Electrical
Characteristics table can be achieved. The maximum
data rate is limited to 3Mbps by the speed-up circuitry.
The MAX3370/MAX3371 may also be used to translate
unidirectional signals without signal inversion. The
devices provide the smallest solution (SC70 package)
for unidirectional level translation without inversion.
