SX1503 16 Channel Low Voltage GPIO

The SX1501, SX1502 and SX1503 are complete ultra low voltage General Purpose parallel Input/Output (GPIO) expanders ideal for low power handheld battery powered equipment. They allow easy serial expansion of I/O through a standard I2C interface. GPIO devices can provide additional control and monito.

SX1503 Features

* 4/8/16 channel of I/Os True bi-directional style I/O Programmable Pull-up/Pull-down Push/Pull outputs

* 1.2V to 5.5V independent operating voltage for all supply rails (VDDM, VCC1, VCC2)

* 5.5V compatible I/Os, up to 24mA output sink (no total sink current limit)
