DiodesZetex 48-Channel I/O Expander I2C 56-Pin TQFN, PI4IOE5V96248ZLEX

The DiodesZetex General purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus I2C-bus and is a part of the Fast mode Plus family. It supports high I2C bus drive so that many more devices can be on the bus without the need for bus buffers, high total package sink capacity that supports having all 25 mA LEDs on at the same time and more device addresses are available to allow many more devices on the bus without address conflicts.
