DESCRIPTION/ORDERING INFORMATION
This 8-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-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 PCA9534A consists of one 8-bit configuration (input or output selection), input port, output port, and polarity
inversion (active high or active low) register. At power on, the I/Os are configured as inputs. However, 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 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 PCA9534A 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.
The PCA9534A open-drain interrupt (INT) output is activated when any input state differs from its corresponding
input port register state and is used to indicate to the system master that an input state has changed.
