KTS1622 Low Voltage 16-Bit I2C-bus I/O Expanders

Kinetic Technologies KTS1622 Low Voltage 16-Bit I²C-bus I/O Expanders are designed for microcontrollers when additional I/Os are required with minimum interconnections. The KTS1622 features separate power rails (VDD_I²C and VDD_P) for I²C bus and I/O ports; both range from 1.65V to 5.5V. These rails allow a mixed power system where I²C bus power is incompatible with I/O port power.
