PCAL6416 ALow-voltage translating 16-bit I2C-bus/SMBus I/O expanderwith interrupt output, reset, and configuration registersRev. 7 30 March 2021 Product data sheet 1 General descriptionThe PCAL6416A is a 16-bit general-purpose I/O expander that provides remote I/Oexpansion for most microcontroller families via the I2C-bus I/O expanders provide a simple solution when additional I/Os are needed whilekeeping interconnections to a minimum, for example, in battery-powered mobileapplications for interfacing to sensors, push buttons, keypad, etc. In addition to providinga flexible set of GPIOs, it simplifies interconnection of a processor running at onevoltage level to I/O devices operating at a different (usually higher) voltage level.
