LTC4301
U U U PI FU CTIO S CS (Pin 1):
The connection sense pin is a 1.4V threshold when the start-up sequence described in the Operation digital input pin. For normal operation CS is grounded. section has not been completed. READY goes high when Driving CS above the 1.4V threshold isolates SDAIN from CS is low and a start-up is complete. SDAOUT and SCLIN from SCLOUT and asserts READY
SDAIN (Pin 6):
Serial Data Input. Connect this pin to the low. SDA bus on the backplane.
SCLOUT (Pin 2):
Serial Clock Output. Connect this pin to
SDAOUT (Pin 7):
Serial Data Output. Connect this pin to the SCL bus on the card. the SDA bus on the card.
SCLIN (Pin 3):
Serial Clock Input. Connect this pin to SCL
V
on the bus backplane.
CC (Pin 8):
Main Input Supply. Place a bypass capacitor of at least 0.01µF close to VCC for best results.
GND (Pin 4):
Ground. Connect this pin to a ground plane
Exposed Pad (Pin 9):
Exposed pad may be left open or for best results. connected to device ground.
READY (Pin 5):
The READY pin is an open drain N-channel MOSFET output which pulls down when CS is high or
