*THE SLAVE ADDRESS IS DETERMINED BY ADDRESS PIN A0.
Figure 3. DS3508 Slave Address Byte
Slave Address Byte and Address Pin
The slave address byte consists of a 7-bit slave
address plus a R/W bit (see Figure 3). The DS3508’s
slave address is determined by the state of the A0 pin.
This pin allows up to two devices to reside on the same
I2C bus. Connecting A0 to GND results in a 0 in the
corresponding bit position in the slave address.
Conversely, connecting A0 to VCC results in a 1 in the
corresponding bit position. For example, the DS3508’s
slave address byte is E8h when A0 is grounded. I2C
communication is described in detail in the I2C Serial
Interface Description section.
