The Texas Instruments PCA9539DGVR is a 16-bit I2C and SMBus compatible IO expander. It is designed to provide additional digital I/O pins for microcontrollers. The device operates with a supply voltage ranging from 2.3V to 5.5V and supports a maximum clock frequency of 400kHz.
Key features include 16 I/O pins, an interrupt output, and a reset input. The I/O ports are 5V tolerant, making them compatible with a wide range of microcontrollers. The PCA9539DGVR is available in a 24-TVSOP package and is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C.
This IO expander is ideal for applications requiring more digital I/O pins than are available on the main microcontroller. Its I2C/SMBus interface allows for easy integration into existing systems. The latched outputs offer high-current drive capability for directly driving LEDs.
