PIN DESCRIPTIONS
Serial Clock (SCL)
The SCL input is used to clock all data into and out of
the device.
Serial Data (SDA)
SDA is a bidirectional pin used to transfer data into and
out of the device. It is an open drain output and may be
wire-ORed with any number of open drain or open col-
lector outputs.
An open drain output requires the use of a pull-up
resistor. For selecting typical values, refer to the Pull-Up
Resistor selection graph at the end of this data sheet.
Address (A
0
, A
1
, A
2
)
A0 is a no connect. The Address inputs (A
1
, A
2
) are
used to set the appropriate bits of the seven bit slave
address. These inputs can be used static or actively
driven. If used statically they must be tied to V
SS
or
V
CC
as appropriate. If driven they must be driven to
V
SS
or to V
CC
.

PIN CONFIGURATION
DEVICE OPERATION
The X24C04 supports a bidirectional bus oriented pro-
tocol. The protocol defines any device that sends data
onto the bus as a transmitter, and the receiving device
as the receiver. The device controlling the transfer is a
master and the device being controlled is the slave.
The master will always initiate data transfers, and pro-
vide the clock for both transmit and receive operations.
Therefore, the X24C04 will be considered a slave in all
applications.
Clock and Data Conventions
Data states on the SDA line can change only during
SCL LOW. SDA state changes during SCL HIGH are
reserved for indicating start and stop conditions. Refer
to Figures 1 and 2.
Start Condition
All commands are preceded by the start condition,
which is a HIGH to LOW transition of SDA when SCL is
HIGH. The X24C04 continuously monitors the SDA and
SCL lines for the start condition and will not respond to
any command until this condition has been met.
