PCAL9722 Ultra Low-Voltage 22-bit I/O Expanders

NXP Semiconductors PCAL9722 Ultra Low-Voltage 22-bit I/O Expanders offer remote I/O expansion for microcontroller families via the SPI interface. These expanders feature a built-in level shifting that makes devices highly flexible in mixed power supply systems where communication between incompatible I/O voltages is required. The PCAL9722 ultra low-voltage 22-bit I/O allows direct connection to a microcontroller operating down to 1.1V. Typical applications include IoT, industrial controllers, LED driving devices, building automation, telecom equipment, routers, servers, personal electronics, gaming consoles, and computers.
