Description
The TCA9534 is a 16-pin device that provides 8 bits
of general purpose parallel input and 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 V to 5.5 V,
which allows for use with a wide range of devices.
The device supports both 100-kHz (Standard-mode)
and 400-kHz (Fast-mode) clock frequencies. I/O
expanders such as the TCA9534 provide a simple
solution when additional I/Os are needed for
switches, sensors, push-buttons, LEDs, fans, and
other similar devices.
The features of the TCA9534 include an interrupt that
is generated on the INT pin. This allows the master to
know when an input port changes state. The A0, A1,
and A2 hardware selectable address pins allow up to
eight TCA9534 devices on the same I2C bus. The
device can also be reset to its default sate by cycling
the power supply and causing a power-on reset.
