Applications Information
Power-Supply Decoupling
To achieve best results, it is recommended that the power
supply is decoupled with a 0.01F or a 0.1F capacitor.
Use high-quality, ceramic, surface-mount capacitors,
and mount the capacitors as close as possible to the
VCC and GND pins to minimize lead inductance.
SDA and SCL Pullup Resistors
SDA is an open-collector output on the device that
requires a pullup resistor to realize high logic levels. A
master using either an open-collector output with a
pullup resistor or a push-pull output driver can be uti-
lized for SCL. Pullup resistor values should be chosen
to ensure that the rise and fall times listed in the
I2C AC
Electrical Characteristics table are within specification.
Package Information

“-” in the package code indicates RoHS status only. Package
drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
