Applications Information
Power-Supply Decoupling
To achieve the best results when using the DS1089L,
decouple the power supply with 0.01μF and 0.1μF
high-quality, ceramic, surface-mount capacitors.
Surface-mount components minimize lead inductance,
which improves performance, and ceramic capacitors
tend to have adequate high-frequency response for
decoupling applications. These capacitors should be
placed as close to the V
CC
and GND pins as possible.
Stand-Alone Mode
SCL and SDA cannot be left floating even in stand-
alone mode. If the DS1089L will never need to be pro-
grammed in-circuit, including during production
testing, SDA and SCL can be connected high.
