Description
The TCA6416APWR is a 16-bit I²C and SMBus I/O expander with an interrupt output, manufactured by Texas Instruments. It is designed to provide additional I/O ports to microcontrollers or processors using a simple serial interface. The device operates over a wide supply voltage range of 1.65 V to 5.5 V, making it compatible with a variety of logic levels.
Key features of the TCA6416APWR include two I²C-bus address pins allowing up to eight devices on the same bus, interrupt output for monitoring input changes, and low standby current consumption. It also supports fast I²C communication up to 400 kHz, enabling efficient data transfer.
The TCA6416APWR is suitable for applications requiring additional I/O, such as in industrial control, consumer electronics, and embedded systems. Its small package and flexibility make it ideal for space-constrained designs. This expander is a practical solution for extending the number of I/O lines in systems where the host controller has limited GPIO availability.
