TCA9555 Datasheet - Texas Instruments

TCA9555 - Low-Voltage 16-Bit I2C and SMBus I/O Expander

This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 1.65-V to 5.5-V VCC operation.

It provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface.

The TCA9555 consists of two 8-bit Configuration (input or output selection), Inpu
