pull-up resistors from SDAOUT and SCLOUT to this pin.

Place a bypass capacitor of at least 0.01µF close to this pin

for best results.

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 the

SCL bus on the backplane.

GND (Pin 4): Device Ground. Connect this pin to a ground

plane for best results.

ENABLE (Pin 5): Digital CMOS Threshold Input. Ground-

ing this pin puts the part in a low current mode. It also

disables the rise-time accelerators, disables the bus

discharge circuitry, isolates SDAIN from SDOUT and

isolates SCLIN from SCLOUT. For active operation, drive

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.

This is the supply voltage for the devices on the backplane

SCLIN to this pin. Place a bypass capacitor of at least

0.01µF close to this pin for best results.

Exposed Pad (Pin 9, DFN Package Only): Exposed Pad

may by be left open or connected to device ground.
