16-bit I2C-bus/SMBus Level Translating I/O Expander with Interrupt, Reset and Agile I/O in TSSOP24 package

The PCAL6416A is a 16-bit I²C GPIO expander with interrupt and reset functionality, designed to add remote I/O capabilities to microcontrollers. It features a built-in level-shifting mechanism, making it highly flexible in mixed-signal environments. Its wide voltage range across dual power rails enables seamless communication with next-generation low-voltage microprocessors and microcontrollers. The PCAL6416A is a pin-to-pin replacement for the PCA6416A, with additional Agile I/O features.
