PI4IOE5V6416ZDEX I/O Expander from Diodes Incorporated

The PI4IOE5V6416ZDEX from Diodes Incorporated is a 16-bit I²C I/O expander that provides remote I/O expansion for most microcontroller families via the I²C-bus interface. It offers a simple solution when additional I/Os are needed while keeping interconnections to a minimum, making it ideal for battery-powered mobile applications, such as interfacing with sensors, buttons, keypads, and other Human Machine Interface (HMI) devices.

The PI4IOE5V6416ZDEX features a wide operating voltage range of 1.8V to 5.5V, making it compatible with a wide range of microcontrollers. It also has a low operating current of less than 1µA, making it ideal for battery-powered applications.

The PI4IOE5V6416ZDEX is easy to use and configure. It has a simple I²C interface that requires only two signals: SCL and SDA. The device has two address pins, A0 and A1, which allow it to be connected to up to four PI4IOE5V6416ZDEX devices on the same I²C bus.

The PI4IOE5V6416ZDEX has two input/output modes: open-drain and push-pull. In open-drain mode, the output pins can be pulled low by an external device, such as a transistor or pull-up resistor. In push-pull mode, the output pins can be driven high or low by the device itself.

The PI4IOE5V6416ZDEX also has a number of other features, including:

• Programmable interrupt output
• Schmitt trigger inputs
• Output current limiting
• Thermal shutdown

The PI4IOE5V6416ZDEX is available in a 24-pin TQFN package. It is RoHS compliant and halogen-free.
