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