Introducing the PI4IOE5V9535LEX from Diodes Incorporated

The PI4IOE5V9535LEX is a robust, versatile, and high-performance I/O expander IC designed by Diodes Incorporated to meet the needs of complex digital systems. This integrated circuit is an ideal solution for system designers looking to increase the number of I/Os in their projects while maintaining a small footprint and reducing overall system complexity.

At the heart of the PI4IOE5V9535LEX is its ability to interface with the host controller via a standard I²C-bus/SMBus serial interface, which supports up to 400kHz (Fast-mode) and 1MHz (Fast-mode Plus) operation. This feature allows for easy integration into existing designs and provides a simple method for I/O expansion.

The device offers 16-bit I/O port expander functionality, with each I/O configurable as either an input or an output. This flexibility makes it suitable for a wide range of applications, including mobile devices, servers, personal computers, and embedded systems, where additional I/Os are needed for switches, sensors, LEDs, and other peripherals.

One of the key features of the PI4IOE5V9535LEX is its built-in level shifting capability, which allows it to interface with different logic levels, making it compatible with a variety of microcontrollers and processors. The device operates over a wide supply voltage range from 1.65V to 5.5V, enabling it to support both low-voltage and standard-voltage applications.

The PI4IOE5V9535LEX is also designed with power-saving in mind. It includes an active LOW standby mode to conserve power when the device is not in use. Furthermore, the integrated pull-up/pull-down resistors, interrupt output, and weak pull-up resistor on the SDA/SCL inputs contribute to the reduction of external component count, thus simplifying the design and saving board space.

For reliability and durability, the PI4IOE5V9535LEX is offered in a compact TSSOP-24 package, which not only ensures a small footprint but also provides robust protection against environmental factors. With its comprehensive features and Diodes Incorporated's reputation for high-quality semiconductor products, the PI4IOE5V9535LEX stands out as a superior choice for your I/O expansion needs.
