ENABLE/V
CC2
(Pin 1):
Chip Enable Pin/Card Supply Volt-
age. For the LTC4300A-1, this is a digital CMOS threshold
input pin. Grounding this pin puts the part in a low current
(<1
μ
A) mode. It also disables the rise-time accelerators,
disables the bus precharge circuitry, drives READY low,
isolates SDAIN from SDAOUT and isolates SCLIN from
SCLOUT. Drive ENABLE all the way to V
CC
for normal
operation. Connect ENABLE to V
CC
if this feature is not
being used. For the LTC4300A-2, 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):
Ground. Connect this pin to a ground plane
for best results.
READY/ACC (Pin 5):
Connection Flag/Rise-Time Accel-
erator Control. For the LTC4300A-1, this is an open-drain
NMOS output which pulls low when either ENABLE is low
or the start-up sequence described in the Operation sec-
tion has not been completed. READY goes high when
ENABLE is high and start-up is complete. Connect a 10k
resistor from this pin to V
CC
to provide the pull up. For the
LTC4300A-2, this is a CMOS threshold digital input pin
that enables and disables the rise-time accelerators on all
four SDA and SCL pins. Drive ACC all the way to the V
CC2
supply voltage to enable all four accelerators; drive ACC to
ground to turn them off.
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 (and also from SDAOUT and SCLOUT for the
LTC4300A-1) to this pin. Place a bypass capacitor of at
least 0.01
μ
F close to this pin for best results.
