SLUS939B – APRIL 2010 – REVISED DECEMBER 2010
Serial Bus Address
To communicate with the TPS2480/81, the master must first address slave devices via a slave address byte. The
slave address byte consists of seven address bits, and a direction bit indicating the intent of executing a read or
write operation.
The TPS2480/81 have two address pins, A0 and A1. Table 2 describes the pin logic levels for each of the 16
possible addresses. The state of pins A0 and A1 is sampled on every bus communication and should be set
before any activity on the interface occurs. The address pins are read at the start of each communication event.

Serial Interface
The TPS2480/81 operates only as a slave device on the I2C bus and SMBus. Connections to the bus are made
via the open-drain I/O lines SDA and SCL. The SDA and SCL pins feature integrated spike suppression filters
and Schmitt triggers to minimize the effects of input spikes and bus noise. The TPS2480/81 support the
transmission protocol for fast (1 kHz to 400 kHz) and high-speed (1 kHz to 3.4 MHz) modes. All data bytes are
transmitted most significant byte first.
