specification is for the first low level seen by the SDAx/SCLx lines. V

is for the second and subsequent low levels seen by the
SDAx/SCLx lines.
2. The SCL/SDA C

CC
= 0 V. The PCA9515A should be used in applications where power is secured to the repeater but
an active bus remains on either set of SCL/SDA pins.
