10.1.2 Connecting Multiple Devices

Up to three TLA202x devices can be connected to a single I²C bus by using different address pin configurations for each device. Use the address pin to set the TLA202x to one of three different I²C addresses. Figure 19 shows an example with three TLA202x devices on the same I²C bus. One set of pullup resistors is required per bus line. The pullup resistor values may need to decrease to compensate for the additional bus capacitance presented by multiple devices and increased line length.

NOTE:

The TLA202x power and input connections are omitted for clarity. The ADDR pin selects the I²C address.
