概述

Description

The PCA9535EMTTXG is an I2C-bus I/O port expander designed by NXP Semiconductors. It features 16 GPIO pins that can be configured as either input or output, enabling the expansion of microcontroller I/O capabilities. The device operates over a supply voltage range of 2.3V to 5.5V and communicates via the I2C interface, allowing it to connect to multiple devices on the same bus.
Key features include programmable interrupt capabilities, which alert the host device to changes in input states, and the ability to drive up to 25 mA per output, accommodating various connected components. The PCA9535EMTTXG is ideal for applications requiring additional I/O lines, such as LED control, button input, or sensor interfacing in embedded systems. Its small package size and low power consumption make it suitable for space-constrained and battery-operated devices.
