Description
●The TCA6416A is a 24-pin device that provides 16-bits of general purpose parallel input/output (I/O)
●expansion for the two-line bidirectional I2C bus (or SMBus) protocol. The device can operate with a
●power supply voltage ranging from 1.65 V to 5.5 V on the I2C bus side (VCCI) and a power supply voltage ranging from 1.65 V to 5.5 V on the P-port side(VCCP).
