The PCAL6416AHF,128 from NXP Semiconductors is a 16-bit general-purpose I/O expander designed for remote I/O expansion via the I2C-bus interface. It is suitable for applications requiring additional I/Os while minimizing interconnections, such as in battery-powered mobile devices for interfacing with sensors or keypads.
This I/O expander features a wide operating voltage range of 1.65 V to 5.5 V, enabling seamless communication between microcontrollers and peripherals operating at different voltage levels due to its built-in level shifting capabilities. It supports I2C and SMBus interfaces with a clock frequency of up to 400 kHz.
The PCAL6416AHF,128 offers 16 I/O pins with configurable output types including Open Drain and Push-Pull. It operates within a temperature range of -40°C to 85°C and is available in a 24-WFQFN Exposed Pad package, specifically a 24-HWQFN (4x4) supplier package, designed for surface mounting.
Additional features include Power-On Reset (POR) and an interrupt output. The device supports current outputs of 10mA and 25mA.
