Typical Application for SX1508QB Worlds Lowest Voltage Level Shifting GPIO with LED Driver and Keypad Engine
參考設計 屬於: Semtech
Typical Application for the SX1508QB and SX1509QB are complete ultra low voltage General Purpose parallel Input/Output (GPIO) expanders ideal for low power handheld battery powered equipment. This family of GPIOs comes in 8-, 16-channel configuration and allows easy serial expansion of I/O through a standard 400kHz I2C interface. GPIO devices can provide additional control and monitoring when the microcontroller or chipset has insufficient I/O ports, or in systems where serial communication and control from a remote location is advantageous
