BUS INTERFACE
GENERAL DESCRIPTION
The I
2
C bus is a two-way, two-line serial communication
between different integrated circuits. The two lines are: a
serial Data line (SDA) and a serial Clock line (SCL). All
Summit Microelectronics parts support a 100kHz clock
rate, and some support the alternative 400kHz clock.
Check the AC Electrical Table for the value of f
SCL
. The

C Data Timing
SDA line must be connected to a positive supply by a pull-
up resistor located on the bus. Summit parts have a
Schmitt input on both lines. See Figure X1 and Table X1
for waveforms and timing on the bus. One bit of Data is
transferred during each Clock pulse. The Data must
remain stable when the Clock is high.
