Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LTC1555LEGN-1.8 is guaranteed to meet performance

specifications from 0

°C to 70°C. Specifications over the –40°C to 85°C

operating temperature range are assured by design, characterization and

correlation with statistical process controls.

Note 3: The DATA and I/O pull-down drivers must also sink current

sourced by the internal pull-up resistor.
