Applications Information
Power-Supply Decoupling
To achieve the best results when using the DS3514,
decouple all the power-supply pins (VCC and VDD) with
a 0.01F or 0.1F capacitor. Use a high-quality ceramic
surface-mount capacitor if possible. Surface-mount
components minimize lead inductance, which improves
performance, and ceramic capacitors tend to have
adequate high-frequency response for decoupling
applications.
SDA and SCL Pullup Resistors
SDA is an I/O with an open-collector output 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 used
for SCL. Pullup resistor values should be chosen to
ensure that the rise and fall times listed in the
I2C
Electrical Characteristics are within specification. A typ-
ical value for the pullup resistors is 4.7k
Ω.
