Description and Introduction
Remote 16-Bit I2C and SMBus, Low-Power I/O Expander With Interrupt Output and Config Registers 24-TVSOP -40 to 85 # Introduction to the PCA9535DGVR from Texas Instruments  
The PCA9535DGVR is a versatile 16-bit I/O expander designed to enhance the input/output capabilities of microcontrollers and other digital systems. This integrated circuit (IC) operates via an I²C-bus interface, allowing seamless communication with host controllers while minimizing pin usage.   Featuring 16 programmable GPIO pins, the PCA9535DGVR supports both input and output configurations, making it ideal for applications requiring flexible I/O expansion. Each pin can be individually set to operate in push-pull or open-drain mode, providing adaptability for various voltage levels and interfacing requirements.   With an operating voltage range of 2.3V to 5.5V, the device is compatible with a wide array of logic levels, ensuring broad system integration. It also includes interrupt functionality, enabling efficient event-driven processing by alerting the host controller when input states change.   Housed in a compact TSSOP-24 package, the PCA9535DGVR is well-suited for space-constrained designs, including industrial controls, consumer electronics, and embedded systems. Its robust performance, low power consumption, and ease of configuration make it a reliable choice for expanding digital I/O in modern electronic designs. |
