Applications Information
Power-Supply Decoupling
To achieve best results, it is recommended that the power
supply is decoupled with a 0.01µF or a 0.1µF capacitor.
Use high-quality, ceramic, surface-mount capacitors,
and mount the capacitors as close as possible to the
V
CC and GND pins to minimize lead inductance.
SDA and SCL Pullup Resistors
SDA is an open-collector output on the DS1874 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
I 2 C AC
Electrical Characteristics table are within specification.
