NCT5635Y

I/o Expanders Overview

The NCT5635Y is an SMBus GPIO expander manufactured by Nuvoton Technology Corporation. It provides 16 general-purpose input/output pins accessible via the SMBus interface. The device operates within a voltage range of 2.7V to 5.5V, ensuring compatibility with various system power rails. Classified under interface I/O expanders, it serves as a peripheral expansion solution for embedded systems requiring additional digital I/O capabilities without consuming primary microcontroller pins.

I/o Expanders Feature Summary

• Provides 16 dedicated GPIO pins for system expansion
• Interfaces with host controllers using standard SMBus protocol
• Operates across a wide supply voltage range from 2.7V to 5.5V

I/o Expanders Applications

• Embedded systems requiring additional digital control lines
• IoT devices needing expanded input/output connectivity
• Industrial control panels utilizing SMBus communication

I/o Expanders Procurement Notes

Verify the specific package type and tape-and-reel specifications against the official datasheet before ordering. Confirm that the 2.7V to 5.5V operating range aligns with your target system's power supply design. Ensure SMBus signal levels are compatible with the host controller to prevent communication errors during integration.

I/o Expanders Selection Notes

Select this component when an SMBus-based I/O expansion is required rather than parallel interfaces. Evaluate the 16-pin capacity against current and future pin requirements. Consider the 2.7V to 5.5V operational window to ensure stability across varying supply conditions in the final application environment.
