voltage for the devices on the card I
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
