The TCA9535PWR is a 16-bit I2C and SMBus I/O Expander with interrupt output and configurable registers provides 16-bits of general purpose parallel input/output (I/O) expansion for the two-line bidirectional I2C bus or (SMBus) protocol. The device can operate with a power supply voltage ranging from 1.65 to 5.5V. I/O expanders, such as the TCA9535, provide general-purpose remote I/O expansion for most microcontroller families via the I2C interface, providing a simple solution when additional I/Os are needed for switches, sensors, push-buttons, LEDs, fans and other similar devices. It 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.
