Product Overview: PCA9534PW-T by NXP Semiconductors

The PCA9534PW-T is a robust, low-voltage 8-bit General Purpose Input/Output (GPIO) expander with an I²C-bus/SMBus interface, designed and manufactured by NXP Semiconductors. This device provides an ideal solution for expanding the I/O capabilities of microcontrollers where additional I/Os are necessary or in systems with limited GPIOs available. Its compact TSSOP16 (thin shrink small outline package) makes it suitable for space-constrained applications.

Key Features

• I²C Interface: PCA9534PW-T operates through a bidirectional I²C-bus and is compatible with SMBus standards, allowing for easy integration with most microcontrollers.
• Operating Voltage: The device supports a wide range of supply voltages from 2.3V to 5.5V, making it versatile for various logic levels and suitable for battery-operated applications.
• GPIO Expansion: It offers eight programmable I/O pins, which can be used as either inputs or outputs, providing significant expansion capabilities.
• Interrupt Output: An interrupt output is provided, which can be configured to reflect the status of the input pins, allowing for immediate system responses to input changes.
• Polarity Inversion: Input polarity can be inverted if required, which is useful for adapting to different logic configurations.
• Low Standby Current: The PCA9534PW-T is designed for low power consumption, with a low standby current that is ideal for power-sensitive applications.
