Diodes’ PI4IOE5V6416 16-bit general purpose I/O expander provides remote I/O expansion for most microcontroller families via the I2C-bus interface. It provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum. In battery-powered mobile applications for interfacing to sensors, pushbuttons, and keypads, it operates from 1.65 V to 5.5 V on the GPIO-port side and 1.65 V to 5.5 V on the SDA/SCL side (I2C-bus interface). This allows the PI4IOE5V6416 to interface with next-generation microprocessors and microcontrollers on the SDA/SCL side where supply levels are reducing to conserve power. The PI4IOE5V6416 is available in the industry standard TSSOP-24 and TQFN-24 packages.
