... I serial interface logic compatible with SMBus. The sys- tem master can invert the MAX7318 input data by writing to the active-high polarity inversion register. Any of the 16 I/O ports can be configured as an input or output ...

... DC Output Current on I/O0–I/O15 ....................................±80mA Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... B Note 4: The maximum t for the SDA and SCL bus lines is specified at 300ns. The maximum fall time for the SDA output stage t F specified at 250ns. This allows series protection resistors to be connected between the SDA and SCL pins and the SDA/SCL bus lines without exceeding the maximum specified t Note 5: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns ...

... HD,DAT t F REPEATED START CONDITION The MAX7318 operates as a slave that sends and receives data through a 2-wire interface. The interface uses a serial data line (SDA) and a serial clock line (SCL) to achieve bidirectional communication between master(s) and slave(s). A master, typically a microcon- troller, initiates all data transfers to and from the MAX7318, and generates the SCL clock that synchro- nizes the data transfer (Figure 2) ...

... The master generates the 9th clock pulse, and the recipient pulls down SDA during the acknowledge clock pulse, such that the SDA line is sta- ble low during the high period of the clock pulse. When the master is transmitting to the MAX7318, the MAX7318 P STOP CONDITION ...

... Figure 7). The command byte is used to deter- mine which of the following registers are written or read. Transmit data to the MAX7318 by sending the device slave address and setting the LSB to a logic zero. The command byte is sent after the address and deter- ...

... After a restart, the bus master must then send the MAX7318 address with the R/W bit set to 1. Data from the register defined by the com- mand byte is then sent from the MAX7318 to the master (Figures 8, 9). ACKNOWLEDGE DATA FROM LOWER OR ...

... Standby supply current is typically 5.4µA. The I/O ports I/O0–I/O15, interrupt output INT, and serial interface SDA, SCL, AD0–2 remain high impedance with asserted on them when the MAX7318 is pow- ered down (V+ = 0V). The MAX7318 can therefore be used in hot-swap applications. Note that each I/O’s 100kΩ ...
