INTL9554 is a 16-pin device that provides 8-bit general-purpose parallel input and output expansion for a two-wire bidirectional I2C bus (or SMBus). The device operates from a supply voltage ranging from 1.65V to 5.5V. The INTL9554 functions include generating an interrupt on the INT pin when the state of the input port changes. The A0, A1, and A2 hardware selectable address pins allow up to 8 INTL9554 devices on the same I2C bus.
