PI4IOE5V9555ZDEX Description

Short technical summary and product information.

The PI4IOE5V9555ZDEX from Diodes Incorporated is a 16-bit I2C-bus and SMBus I/O expander designed to provide general-purpose parallel input/output expansion for I2C/SMBus applications. It features 16 programmable I/O pins that can be configured as either inputs or outputs.

 

This device operates with a power supply voltage ranging from 2.3V to 5.5V and supports a clock frequency up to 400kHz. The I/Os are 5V tolerant, offering flexibility in system design. It includes an active-low interrupt output that signals changes in input states.

 

The PI4IOE5V9555ZDEX is offered in a 24-VFQFN exposed pad package, suitable for surface mounting. The operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. This I/O expander is ideal for applications requiring additional I/O for components like ACPI power switches, sensors, push buttons, LEDs, and fans.
