onsemi CAT9555HV6I-G is a 16-bit I/O expander featuring I2C and SMBus interfaces with a maximum clock frequency of 400 kHz. This device is designed for efficient expansion of microcontroller I/O capabilities. It offers 16 individually configurable I/O pins that can be set as inputs or outputs, with a push-pull output type. The expander includes a Power-On Reset (POR) feature and an interrupt output for system event notification.
The CAT9555HV6I-G operates across a wide supply voltage range of 2.3V to 5.5V, making it suitable for diverse power environments. It supports source and sink currents of 10mA and 24mA respectively. Packaged in a 24-TQFN (4x4) with an exposed pad for improved thermal performance, this component is designed for surface mounting. Typical applications include industrial automation, consumer electronics, and automotive systems where increased I/O density is required.
