To achieve the best results when using the DS1087L,
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

SCL and SDA cannot be left floating even in stand-
alone mode. If the DS1087L never needs to be pro-
grammed in-circuit, including during production
testing, SDA and SCL can be wired high.
