2.0
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1:
2.1
This is a bidirectional pin used to transfer addresses
and data into and out of the device. It is an open drain
terminal. Therefore, the SDA bus requires a pull-up
resistor to V
400 kHz).
For normal data transfer, SDA is allowed to change
only during SCL low. Changes during SCL high are
reserved for indicating the Start and Stop conditions.
2.2
The SCL input is used to synchronize the data transfer
to and from the device.
2.3
The A0, A1 and A2 inputs are used by the 24AA024H/
24LC024H for multiple device operations. The levels
on these inputs are compared with the corresponding
bits in the slave address. The chip is selected if the
compare is true.
Up to eight 24AA024H/24LC024H devices may be
connected to the same bus by using different Chip
Select bit combinations. These inputs must be
connected to either V
In most applications, the chip address inputs A0, A1
and A2 are hard-wired to logic ‘0’ or logic ‘1’. For
applications in which these pins are controlled by a
microcontroller or other programmable device, the chip
address pins must be driven to logic ‘0’ or logic ‘1’
before normal device operation can proceed.

The SCL and SDA inputs have Schmitt Trigger and
filter circuits that suppress noise spikes to assure
proper device operation even on a noisy bus.
