16-Port I/O Expander with LED Intensity  
Control, Interrupt, and Hot-Insertion Protection  
MAX713  
General Description  
Features  
The MAX7313 I2C-compatible serial interfaced periph-  
eral provides microprocessors with 16 I/O ports. Each  
I/O port can be individually configured as either an  
open-drain current-sinking output rated at 50mA and  
5.5V, or a logic input with transition detection. A 17th  
port can be used for transition detection interrupt, or as  
a general-purpose output. The outputs are capable of  
driving LEDs, or providing logic outputs with external  
resistive pullup up to 5.5V.  
o 400kbs, 2-Wire Serial Interface, 5.5V Tolerant  
o 2V to 3.6V Operation  
o Overall 8-Bit PWM LED Intensity Control  
Global 16-Step Intensity Control  
Individual 16-Step Intensity Controls  
o Two-Phase LED Blinking  
o High Output Current (50mA max Per Port)  
o Outputs are 5.5V-Rated Open Drain  
o Supports Hot Insertion  
PWM current drive is integrated with 8 bits of control.  
Four bits are global control and apply to all LED outputs  
to provide coarse adjustment of current from fully off to  
fully on with 14 intensity steps. Each output then has  
individual 4-bit control, which further divides the global-  
ly set current into 16 more steps. Alternatively, the cur-  
rent control can be configured as a single 8-bit control  
that sets all outputs at once.  
o Inputs are Overvoltage Protected to 5.5V  
o Transition Detection with Interrupt Output  
o 1.2µA (typ), 3.6µA (max) Standby Current  
o Small 4mm x 4mm TQFN Package  
o -40°C to +125°C Temperature Range  
o All Ports Can Be Configured as Inputs or Outputs  
The MAX7313 is pin and software compatible with the  
MAX7311, PCA9535, and PCA9555.  
Ordering Information  
Each output has independent blink timing with two blink  
phases. All LEDs can be individually set to be on or off  
during either blink phase, or to ignore the blink control.  
The blink period is controlled by a register.

The MAX7313 supports hot insertion. All port pins, the  
INT output, SDA, SCL, and the slave-address inputs  
ADO-2 remain high impedance in power-down (V+ =0V)  
with up to 6V asserted upon them.  
+Denotes a lead(Pb)-free/RoHS-compliant package.  
*EP = Exposed Pad.  
Pin Configurations  
The MAX7313 is controlled through the 2-wire  
I2C/SMBus serial interface, and can be configured to  
any one of 64 I2C addresses.
