Product Overview: Texas Instruments PCF8575DGVR

The Texas Instruments PCF8575DGVR is a robust I/O expander that provides the flexibility of additional I/O ports for microcontroller-based systems. This particular model is part of the PCF8575 series, which is renowned for its ability to significantly expand the I/O capabilities of a microcontroller or microprocessor through a two-wire I²C-bus interface.

Key Features

• I/O Expander: The device offers 16-bit, general-purpose parallel I/O expansion for I²C bus or SMBus applications.
• Interface: It operates through an I²C interface, which allows for easy integration into existing systems with minimal wiring, supporting both 100 kHz (Standard-mode) and 400 kHz (Fast-mode) I²C protocols.
• Operating Voltage: The PCF8575DGVR operates within a voltage range of 2.5V to 5.5V, making it suitable for a wide array of applications and compatible with logic levels of various microcontrollers.
• Package: Available in a compact TSSOP (Thin Shrink Small Outline Package) 24-pin configuration, it is designed for space-constrained applications.
• Addressing: Up to eight PCF8575 devices can share the I²C bus, providing up to 128 additional I/Os; the address is determined by three hardware address pins (A0, A1, A2).
• Interrupt Output: An active LOW interrupt output signals the host microcontroller when input state changes occur, reducing the need for the microcontroller to continuously poll the inputs.
