Description
Chip enable. Grounding this input puts the part in a Low current (< 1 A)
mode. It also disables the rise time accelerators, isolates SDAIN from
SDAOUT and isolates SCLIN from SCLOUT.
serial clock output to and from the SCL bus on the card
serial clock input to and from the SCL bus on the backplane
ground supply; connect this pin to a ground plane for best results
open-drain output which pulls LOW when SDAIN and SCLIN are
disconnected from SDAOUT and SCLOUT, and goes HIGH when the two
sides are connected
serial data input to and from the SDA bus on the backplane
