Description
The PCA9535BS118 is a 16-bit I/O port expander with I2C bus interface, manufactured by NXP Semiconductors. It is designed to provide additional I/O ports for microcontrollers with limited I/O capabilities, facilitating the expansion of digital inputs and outputs in a system. The device operates on a supply voltage ranging from 2.3V to 5.5V, making it suitable for a variety of applications in both 3.3V and 5V systems.
Key features of the PCA9535BS118 include two 8-bit Configuration (Input/Output) ports, individually programmable as inputs or outputs. Each I/O port can sink or source up to 25mA, allowing it to drive LEDs directly or interface with other digital logic levels. The device also includes interrupt capabilities, alerting the microcontroller to changes in input port data.
Communication with the PCA9535BS118 is handled via the I2C bus, supporting standard (up to 100 kHz) and fast (up to 400 kHz) modes. Its small TSSOP package makes it an ideal choice for space-constrained applications. Typical uses include consumer electronics, industrial control, and computing peripherals.
