Output Port Registers  
Standby  
The MAX7318 goes into standby when the I2C bus is  
idle. Standby supply current is typically 5.4µA.  
The output port registers (Table 3) set the outgoing  
logic levels of the I/Os defined as outputs by the  
respective configuration register. Reads from the out-  
put port registers reflect the value that is in the flip-flop  
controlling the output selection, not the actual I/O value.  
Applications Information  
Hot Insertion  
The I/O ports I/O0–I/O15, interrupt output INT, and serial  
interface SDA, SCL, AD0–2 remain high impedance with  
up to 6V 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  
100kpullup effectively becomes a 100kpulldown  
when the MAX7318 is powered down.  
Polarity Inversion Registers  
The polarity inversion registers (Table 4) enable polarity  
inversion of pins defined as inputs by the respective  
port configuration registers. Set the bit in the polarity  
inversion register to invert the corresponding port pin’s  
polarity. Clear the bit in the polarity inversion register to  
retain the corresponding port pin’s original polarity.  
Power-Supply Consideration  
The MAX7318 operates from a supply voltage of 2V to  
5.5V. Bypass the power supply to GND with a 0.047µF  
capacitor as close to the device as possible. For the  
QFN version, connect the exposed pad to GND.  
Configuration Registers  
The configuration registers (Table 5) configure the  
directions of the I/O pins. Set the bit in the respective  
configuration register to enable the corresponding port  
as an input. Clear the bit in the configuration register to  
enable the corresponding port as an output.
