DESCRIPTION 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 program and vary the fixed I2C address and allow up to four devices to share the same I2C bus.
The TCA1116 consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity Inversion (active-high or active-low operation) registers.
At power-on, the I/Os are configured as inputs.
The system master can enable the I/Os as either inputs or outputs by ...
