ON Semiconductor CAT9532HV6I-GT2

The CAT9532HV6I-GT2 from ON Semiconductor is a high-performance, 16-bit I/O port expander with an I²C/SMBus compatible interface. This versatile component is designed for use in a wide range of applications where an additional I/O is required. It is particularly useful for expanding the number of I/Os available to a microcontroller or microprocessor, which can be crucial in complex embedded systems.

The device features 16 I/O ports which can be individually set to either a high or low state. Furthermore, each I/O port can be configured as an input or output, providing excellent flexibility. This makes the CAT9532HV6I-GT2 ideal for driving LEDs, reading button states, or interfacing with various sensors and other peripherals that require digital I/O functionality.

One of the key advantages of the CAT9532HV6I-GT2 is its built-in level shifting capability. This allows the device to interface with different logic levels, which is essential for modern mixed-voltage systems. It supports an input voltage range of 2.3V to 5.5V, making it compatible with most common logic levels used in today's electronics.

The device also offers an interrupt output which can be configured to alert the host controller when an input state changes, reducing the need for the host to continuously poll the expander. This feature is particularly useful for power-sensitive applications as it allows the host processor to remain in a low-power sleep mode until an important event occurs.

For ease of use, the CAT9532HV6I-GT2 includes internal power-on reset and no external reset is required. It also has an active LOW reset input, which can reset the device through external hardware if necessary. The device is available in a TSSOP-24 package, ensuring a compact footprint suitable for space-constrained applications.

With its robust feature set and ON Semiconductor's commitment to quality, the CAT9532HV6I-GT2 is a reliable choice for designers looking to enhance the I/O capabilities of their systems without increasing complexity or power consumption.
