SX1508BIULTRT Description

Short technical summary and product information.

The Semtech SX1508BIULTRT is an ultra low voltage General Purpose parallel Input/Output (GPIO) expander, ideal for low-power handheld battery-powered equipment. This 8-channel device allows for easy serial expansion of I/O through a standard 400kHz I2C interface, providing additional control and monitoring capabilities when a microcontroller has insufficient I/O ports.

 

Key electrical specifications include an operating voltage range of 1.2V to 3.6V and an I2C interface operating at up to 400 kHz. The output type is Open Drain, Push-Pull, and it features an interrupt output. The device is suitable for applications requiring level shifting between different voltage levels.

 

Packaged in a 20-UFQFN Exposed Pad with a 20-QFN-UT (3x3) supplier package, the SX1508BIULTRT is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C, making it versatile for various environmental conditions.
