LTC4300A-3
pin FuncTions (DFN/MSOP) VCC2 (Pin 1):
Card Supply Voltage. This is the supply isolates SCLIN from SCLOUT. For active operation, drive voltage for the devices on the card I2C busses. Connect this pin to VCC. If this feature is unused, tie to VCC. Since pull-up resistors from SDAOUT and SCLOUT to this pin. ENABLE is VCC referenced, do not connect to VCC2 or Place a bypass capacitor of at least 0.01µF close to this pull up to VCC2. pin for best results.
SDAIN (Pin 6):
Serial Data Input. Connect this pin to the
SCLOUT (Pin 2):
Serial Clock Output. Connect this pin to SDA bus on the backplane. the SCL bus on the card.
SDAOUT (Pin 7):
Serial Data Output. Connect this pin to
SCLIN (Pin 3):
Serial Clock Input. Connect this pin to the the SDA bus on the card. SCL bus on the backplane.
VCC (Pin 8):
Main Input Power Supply from Backplane.
GND (Pin 4):
Device Ground. Connect this pin to a ground This is the supply voltage for the devices on the backplane plane for best results. I2C busses. Connect pull-up resistors from SDAIN and
ENABLE (Pin 5):
Digital CMOS Threshold Input. Ground- SCLIN to this pin. Place a bypass capacitor of at least ing this pin puts the part in a low current mode. It also 0.01µF close to this pin for best results. disables the rise time accelerators, disables the bus
Exposed Pad (Pin 9, DFN Package Only):
Exposed pad discharge circuitry, isolates SDAIN from SDOUT and may by be left open or connected to device ground. 4300a3fa 5 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Typical Performance Characteristics Pin Functions Block Diagram Operation Applications Information Package Description Revision History Related Parts Typical Application
