PCA9534A
SCPS141I – SEPTEMBER 2006 – REVISED JUNE 2014
PCA9534A Remote 8-BIT I
2
C and SMBus Low-Power I/O Expander With Interrupt Output
And Configuration Registers
1 Features
1
2 Description
This 8-bit I/O expander for the two-line bidirectional
bus (I
2
C) is designed for 2.3-V to 5.5-V V
CC
operation. It provides general-purpose remote I/O
expansion for most microcontroller families via the I
2
C
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
I
2
C/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.
The PCA9534A and PCA9534 are identical, except
for their fixed I
2
C address. This allows for up to 16 of
these devices (8 of each) on the same I
2
C bus.
