Applications Information
Power-Supply Decoupling
To reduce ripple and the chance of transmitting incor-
rect data, bypass V
L
and V
CC
to ground with a 0.1μF
capacitor. See
Typical Operating Circuit.
To ensure full
±15kV ESD protection, bypass V
CC
to ground with a
1μF capacitor. Place all capacitors as close to the
power-supply inputs as possible.

C Level Translation
The MAX3373E
MAX3376E, MAX3378E/MAX3379E
and MAX3390E
MAX3393E level-shift the data present
on the I/O lines between +1.2V and +5.5V, making
them ideal for level translation between a low-voltage
ASIC and an I
2
C device. A typical application involves
interfacing a low-voltage microprocessor to a 3V or 5V
D/A converter, such as the MAX517.
Push-Pull vs. Open-Drain Driving
All devices in the MAX3372E
MAX3379E and
MAX3390E
MAX3393E family may be driven in a push-
pull configuration. The MAX3373E
MAX3376E/
MAX3378E/MAX3379E and MAX3390E
MAX3393E
include internal 10k
resistors that pull up I/O V
L_
and
I/O V
CC_
to their respective power supplies, allowing
operation of the I/O lines with open-drain devices. See
Timing Characteristics
for maximum data rates when
using open-drain drivers.
