Diodes Incorporated PI4IOE5V96248ZLEX Overview

The PI4IOE5V96248ZLEX from Diodes Incorporated is a high-performance, low-voltage 16-bit I/O expander designed for use in a wide range of applications that require additional I/O capabilities. This integrated circuit is part of the versatile Pericom® product line and is engineered to operate with a supply voltage ranging from 1.65V to 5.5V, making it suitable for interfacing with both 3.3V and 5V systems.

With its I²C bus interface, the PI4IOE5V96248ZLEX provides an easy and efficient way to expand the I/O capabilities of microcontrollers and microprocessors, allowing for a significant increase in the number of I/O ports without the need for additional chips. This feature is particularly useful in applications where PCB space is at a premium, such as in portable and wearable devices, consumer electronics, and industrial automation systems.

The device offers a robust set of features, including an interrupt output that can be configured to alert the host controller when an input state changes, thus reducing the need for constant polling and saving valuable processor time. Additionally, the PI4IOE5V96248ZLEX supports both standard (100kHz) and fast (400kHz) I²C speeds, providing flexibility in system design and ensuring compatibility with a broad range of I²C master devices.

Each I/O port can be configured as either an input or an output, giving designers the freedom to tailor the expander to the specific needs of their application. The ports are also equipped with high-current drive capability and built-in weak pull-up/pull-down resistors, further enhancing their versatility.

For reliability and performance, the PI4IOE5V96248ZLEX features over-temperature protection and is built to meet the stringent quality standards expected from Diodes Incorporated. It is available in a compact TSSOP24 package, which is optimized for automated assembly processes and suitable for high-density board layouts.

Whether you are developing consumer electronics, IoT devices, or sophisticated control systems, the PI4IOE5V96248ZLEX from Diodes Incorporated offers a practical solution for expanding I/O capabilities while maintaining a small footprint and high performance.
