V
CC2
(Pin 1):
Card Supply Voltage. This is the supply
voltage for the devices on the card I
2
C busses. Connect
pull-up resistors from SDAOUT and SCLOUT to this pin.
Place a bypass capacitor of at least 0.01
μ
F 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
this pin to V
CC
. If this feature is unused, tie to V
CC
. Since
ENABLE is V
CC
referenced, do not connect to V
CC2
or pull
up to V
CC2
.
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):
Main Input Power Supply from Backplane.
This is the supply voltage for the devices on the backplane
I
2
C busses. Connect pull-up resistors from SDAIN and
SCLIN to this pin. Place a bypass capacitor of at least
0.01
μ
F 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.
