TCAL6416 I²C-bus/SMBus I/O Expander

Texas Instruments TCAL6416 I²C-bus/SMBus I/O Expander allows a general-purpose parallel input/output (I/O) expansion solution for the two-line bidirectional I²C bus (or SMBus) protocol. The TCAL6416 features a 1.08V to 3.6V power supply voltage on the I²C bus side (VCCI) and a power supply voltage ranging from 1.08V to 3.6V on the P-port side (VCCP).
