The Texas Instruments TCA6416PWT is a 16-bit I2C and SMBus I/O expander designed for expanding general-purpose input/output capabilities. It supports bidirectional voltage-level translation and GPIO expansion across various voltage domains, from 1.8V to 5V.
Key electrical specifications include an operating voltage range of 1.65V to 5.5V and a maximum clock frequency of 400 kHz. The device features 16 I/O pins, an active-low reset input, and an active-low interrupt output. It also includes features like a power-on reset, noise filtering on SCL/SDA inputs, and latched outputs with high-current drive capability.
Packaged in a 24-TSSOP, the TCA6416PWT is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C. The device is noted as not recommended for new designs, but remains available for existing customers.
This I/O expander is useful in applications requiring additional digital I/O pins without increasing the complexity of the main controller interface. Its voltage translation capabilities make it versatile for interfacing between systems with different logic levels.
