1 — 30 August 2022 Product data sheet 1 General description The PCAL6416A is a 16-bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the I2C-bus interface.
NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in battery-powered mobile applications for interfacing to sensors, push buttons, keypad, etc.
In addition to providing a flexible set of GPIOs, it simplifies interconnection of a processor running at one voltage level to I/O devices operating at a different (usually higher) voltage level.
The PCAL6416A has built-in level shifting feature that makes these devices extremely flexible in mixed signal environments where communication between incompatible I/O voltages is required.
Its wide VDD range of 1.
65 V to 5.
5 V...
