LTC4307-1
U U U PI FU CTIO S ENABLE (Pin 1):
Connection Enable Input. This is a 1.4V pulls low when ENABLE is low, or when the start-up and digital threshold input pin. For normal operation pull or tie connection sequence described in the Operation section ENABLE high. Driving ENABLE below 0.8V isolates SDAIN has not been completed. READY goes high when ENABLE from SDAOUT, SCLIN from SCLOUT and asserts READY is high and a connection is made. READY can be used to low. A rising edge on ENABLE after a fault has occurred control the HDMI HPD signal. Connect a pull-up resistor, forces a connection between SDAIN, SDAOUT and SCLIN, typically 10k, from this pin to VCC to provide the pull-up. SCLOUT. Connect to VCC if unused. This pin can be fl oated if unused.
SCLOUT (Pin 2):
Serial Clock Output. Connect this pin to
SDAIN (Pin 6):
Serial Data Input. Connect this pin to the the clock line of a DDC bus. A pull-up resistor should be data line of a DDC bus. A pull-up resistor should be con- connected between this pin and a supply voltage greater nected between this pin and a supply voltage greater than than or equal to the VCC voltage. or equal to the VCC voltage.
SCLIN (Pin 3):
Serial Clock Input. Connect this pin to
SDAOUT (Pin 7):
Serial Data Output. Connect this pin to the clock line of a DDC bus. A pull-up resistor should be the data line of a DDC bus. A pull-up resistor should be connected between this pin and a supply voltage greater connected between this pin and a supply voltage greater than or equal to the VCC voltage. than or equal to the VCC voltage.
GND (Pin 4):
Device Ground. Connect this pin to a ground
VCC (Pin 8):
Supply Voltage Input. Place a bypass capacitor plane for best results. of at least 0.01μF close to VCC for best results.
READY (Pin 5):
Connection READY Status Output. The
Exposed Pad (Pin 9, DFN Package Only):
Exposed Pad READY pin is an open-drain N-channel MOSFET output that may be left open or connected to device ground. 43071fa 6
