BLOCK DIAGRA
ENABLE (Pin 1): Connection Enable. This is a digital
threshold input pin. For normal operation ENABLE is high.
Driving ENABLE below 0.8V isolates SDAIN from SDAOUT,
SCLIN from SCLOUT, asserts READY low and disables
automatic clocking. A rising edge on ENABLE after a fault
has occurred unconditionally forces a connection between
SDAIN, SDAOUT and SCLIN, SCLOUT.
SCLOUT (Pin 2): Serial Clock Output. Connect this pin to
the SCL bus on the card.
SCLIN (Pin 3): Serial Clock Input. Connect this pin to SCL
on the bus backplane.
GND (Pin 4): Device Ground. Connect this pin to a ground
plane for best results.
READY (Pin 5): Connection Status Flag. READY provides
a digital ag which indicates the status of the connection
circuitry described in the Connection Circuitry section.
Connect a resistor of 10k to V
CC
to provide the pull-up.
SDAIN (Pin 6): Serial Data Input. Connect this pin to the
SDA bus on the backplane.
SDAOUT (Pin 7): Serial Data Output. Connect this pin to
the SDA bus on the card.
V
CC
(Pin 8): Supply Voltage Input. Place a bypass capacitor
of at least 0.01礔 close to V
CC
for best results.
Exposed Pad (Pin 9, DFN Only): Exposed pad may be left
open or connected to the ground plane.
