F ceramic capacitor when operating from split sup-
plies or connected to GND for single supply operation.
GND (Pin 11):
Ground Pin.
A1, AO (Pin 12, Pin 13):
Address Selection Pins. Tie these
two pins to either V
CC
or GND to select one of four possible
addresses to which the LTC1380/LTC1393 will respond.
SDA (Pin 14):
SMBus Bidirectional Digital Input/Output
Pin. This pin has an open-drain output and requires a pull-
up resistor or current source to the positive supply for
normal operation. Data is shifted into and acknowledged
by the LTC1380/LTC1393 using this pin.
SCL (Pin 15):
SMBus Clock Input. SDA data is shifted in
at rising edges of this clock during data transfer.
V
CC

Positive Supply Pin. This pin should be
bypassed to GND with a 0.1
