XRA1206 Datasheet (Exar) - 8-BIT I2C/SMBUS GPIO EXPANDER

XRA1206, 8-BIT I2C/SMBUS GPIO EXPANDER

The XRA1206 is an 8-bit GPIO expander with an I2C/ SMBus interface.

After power-up, the XRA1206 has internal 100K ohm pull-up resistors on each I/O pin that can be individually enabled.

In addition, the GPIOs on the XRA1206 can individually be controlled and configured.

As outputs, the GPIOs can be
