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 24VL024/
24VL025 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 24VL024/24VL025 devices (four for the
SOT-23 package) 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.
