TCA1116 LOW VOLTAGE 16-BIT I2C 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 [serial clock (SCL), serial data (SDA)]. Two hardware pins (A0 and A1) are used to.
