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 pos-
sible to the VCC2/VCC3 and GND pins to minimize lead
inductance.
SDA and SCL Pullup Resistors
SDA is an open-collector bidirectional data pin on the
DS1862A that requires a pullup resistor to realize high
logic levels. Either an open-collector output with a pullup
resistor or a push-pull output driver can be utilized for
the SCL input. Pullup resistor values should be chosen
to ensure that the rise and fall times listed in the
I2C AC
Electrical Characteristics are within specification.
