DESCRIPTION/ORDERING INFORMATION  
This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 1.65-V to 5.5-V VCC operation. It  
provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock  
(SCL), serial data (SDA)].  
The TCA9535 consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity  
Inversion (active-high or active-low operation) registers. At power on, the I/Os are configured as inputs. The  
system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for  
each input or output is kept in the corresponding Input or Output Port register. The polarity of the Input Port  
register can be inverted with the Polarity Inversion register. All registers can be read by the system master.  
The system master can reset the TCA9535 in the event of a timeout or other improper operation by utilizing the  
power-on reset feature, which puts the registers in their default state and initializes the I2C/SMBus state machine.
