Description

The PCA9534BS3,118 is an I²C-bus I/O port expander designed for applications requiring additional GPIO (General Purpose Input/Output) pins. It features 8 bits of input/output, allowing users to control or read the state of various devices, such as LEDs or switches, via a serial interface.
This device operates with a supply voltage range of 2.3V to 5.5V and supports multiple I²C-bus addresses, enabling connection of up to eight PCA9534 devices on the same bus. It includes an interrupt output pin that alerts the host controller to changes in the input state, simplifying the monitoring of multiple inputs.
The PCA9534 is particularly useful in systems where pin count is limited, providing an efficient way to expand the number of controllable peripherals while minimizing board space. Its integration capabilities make it suitable for consumer electronics, industrial controls, and other embedded systems.

Features

The PCA9534BS3,118 is an I2C-bus I/O port expander from NXP Semiconductors. It features:
- 16 GPIO pins: Configurable as input or output.
- I2C Interface: Supports standard mode (100 kHz) and fast mode (400 kHz).
- Interrupt functionality: Can generate interrupts on input state changes for efficient monitoring.
- Built-in pull-up resistors: For input pins, simplifying circuit design.
- Multiple device support: Up to 8 devices can be connected on the same I2C bus.
- Power supply voltage: Operates from 2.3V to 5.5V, providing flexibility for different system voltages.
- Low power consumption: Ideal for battery-powered applications.
- Wide operating temperature range: Suitable for industrial applications.
This device is often used in applications requiring additional GPIOs, such as LED control, switch detection, or sensor interfacing in embedded systems.

Package

The PCA9534BS3,118 is packaged in a TSSOP (Thin Shrink Small Outline Package) with 16 pins. This package type is designed for space efficiency and allows for a compact design in electronic circuits.

Pinout

The PCA9534BS3,118 is a 16-pin I2C I/O port expander. It features the following pin configuration:
1. Pins 1-8 (P0-P7): These are the GPIO (general-purpose input/output) pins used for interfacing with other digital circuits. They can be configured as either inputs or outputs.
2. Pin 9 (VSS): Ground reference.
3. Pin 10 (VDD): Power supply input, typically 2.3V to 5.5V.
4. Pin 11 (SCL): I2C clock line for communication.
5. Pin 12 (SDA): I2C data line for communication.
6. Pin 13 (A0): I2C address selection pin to set the device's address.
7. Pin 14 (A1): I2C address selection pin (used in combination with A0).
8. Pin 15 (A2): I2C address selection pin (used in combination with A0 and A1).
9. Pin 16 (INT): Interrupt output pin, which signals when an input pin state has changed.
This device expands I/O capabilities for microcontrollers via the I2C bus.
