The PCA9534PW,118 is an integrated circuit (IC) component that provides an easy solution for expanding the number of input/output (I/O) ports available to a microcontroller or microprocessor. It belongs to the PCA9534 series of ICs, which are part of the NXP Semiconductors family.
The PCA9534PW,118 features a total of 8 quasi-bidirectional I/O pins, which can be independently controlled through a two-wire I2C-bus interface. This allows for flexible use in a variety of applications where additional I/O ports are needed.
One of the key features of the PCA9534PW,118 is its compatibility with both 3.3V and 5V systems. This ensures that it can be easily integrated into different designs without the need for additional voltage level shifting circuitry.
Additionally, the PCA9534PW,118 offers a programmable output configuration that allows each I/O pin to be individually set as either an input or output. This flexibility enables the IC to be adapted to various scenarios where different combinations of inputs and outputs are required.
The IC also provides an interrupt output pin, which can be configured to indicate a change in the input states detected by the device. This feature allows for efficient monitoring of the connected devices without the need for continuous polling.
Another notable feature of the PCA9534PW,118 is its low power consumption, making it suitable for battery-powered applications or designs where power efficiency is a priority. It offers a low standby current and can be put into a low-power mode when not actively processing signals.
In summary, the PCA9534PW,118 is an IC component that offers 8 additional I/O ports through an I2C-bus interface. It is compatible with both 3.3V and 5V systems, provides flexible output configuration, includes an interrupt output pin, and has low power consumption. These features make it a versatile and efficient solution for expanding I/O capabilities in a wide range of electronic designs.
