SX1507 Datasheet | SEMTECH

RIPTION The SX1507, SX1508 and SX1509 are plete ultra low voltage 1.2V to 3.6V General Purpose parallel Input/Output (GPIO) expanders ideal for low power handheld battery powered equipment. This family of GPIOs es in 4-, 8-, 16-channel configuration and allows easy serial expansion of I/O through a standard 400k Hz 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 munication and control from a remote location is advantageous. These devices can also act as a level shifter to connect a microcontroller running at one voltage level to a ponent running at a different voltage level, thus eliminating the need for extra...
