9.5.5 Regular I²C Bus Slave Address
The I²C bus slave address of the TLC59208F is shown in Figure 17. Slave address pins A0, A1, and A2 choose
1 of 64 slave addresses. To conserve power, no internal pullup resistors are incorporated on A0, A1, or A2.
Address values, depending on A0, A1, and A2, can be found in Table 1.
NOTE
When using the TLC59208F, reserved I²C bus addresses must be used with caution since
they can interfere with the following:
• Reserved for future use I²C bus addresses (0000 011, 1111 101, 1111 110, 1111 111)
• Slave devices that use the 10-bit addressing scheme (1111 0xx)
• High-speed mode master code (0000 1xx)

The last bit of the address byte defines the operation to be performed. When set to logic 1, a read operation is
selected. When set to logic 0, a write operation is selected.
