XRA1203 - 16-BIT I2C/SMBUS GPIO EXPANDER
The XRA1203 is a 16-bit GPIO expander with an I2C/ SMBus interface.
After power-up, the XRA1203 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.
In addition, the GPIOs on the XRA1203 can individually be controlled and configured.
As outputs, the GPIOs can be
