Description
General part information
TCA9537 Series
The TCA9537 is a 4-bit I/O expander for the I2C bus and is designed for 1.65-V to 5.5-V VCCoperation. It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface.
The system controller can enable the I/Os as either inputs or outputs by writing to the I/O configuration register bits. The data for each input or output is kept in the corresponding input or output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register.
The TCA9537 open-drain interrupt output (INT) is activated when any input differs from its corresponding Input Port register state and is used to indicate to the system controller that an input state has changed.
