VIL specification is for the first low level seen by the SDA/SCL lines. VILc is for the second and subsequent low levels seen

by the SDA/SCL lines.

The SCL/SDA CI is about 200 pF when VCC = 0 V. The STDVE003A should be used in applications where power is

secured to the repeater but an active bus remains on either set of the SDA/SCL pins.
