Diodes Incorporated PI4IOE5V6416 16-bit I²C I/O Expanders

Diodes Incorporated PI4IOE5V6416 16-bit I2C-bus I/O Expanders provide remote I/O expansion for most microcontroller families via the I2C-bus interface. These Diodes Incorporated expanders offer a simple solution when additional I/Os are needed while keeping interconnections to a minimum, such as in battery-powered mobile applications for interfacing with sensors, buttons, keypads, and other Human Machine Interface (HMI) devices.

Diodes Incorporated PI4IOE5V6416 can operate from 1.65V to 5.5V on the GPIO-port side and 1.65V to 5.5V on the SDA/SCL side. This allows the PI4IOE5V6416 to interface with next-generation microprocessors and microcontrollers, where supply levels drop to conserve power.

The PI4IOE5V6416 I/O Expander is offered in 24-lead TSSOP (Thin Shrink Small Outline Package) and TQFN (Thin Quad Flat No-lead) packages for design flexibility. Both package options are lead-free and RoHS-compliant.
