Applic ations Information
Power-S upply Dec oupling
To reduce ripple and the chance of transmitting incor-
rect data, decouple V
CC
and V
L
to ground with a 0.1μF
capacitor as close to the device as possible.
I
2
C Level T ranslation
The MAX3370/MAX3371 are ideal for level translation
between a low-voltage ASIC and an I
2
C device. The
devices
bidirectional natures allow their use in the data
line of I
2
C communications. A typical application is
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
pullup resistors to allow open-drain dri-
ving (see the
Typical Operating Circuit
).
Push-Pull vs. Open-Drain Driving
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.
Unidirectional vs. Bidirectional Level Translator
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.
