It features a 24-bit input/output configuration accessible via the I2C bus protocol. The device supports an interrupt output capability to facilitate efficient event handling. It operates within a supply voltage range of 1.65 V to 5.5 V and supports clock frequencies up to 1 MHz. The component is housed in a TQFN55-32 package suitable for surface mount technology. It offers open drain and push-pull output types, with a maximum power dissipation of 2.778 W and a typical operating current of 1.4 mA.

Feature Summary

• Provides 24 general-purpose I/O pins expandable through a standard two-wire serial interface.
• Includes dedicated interrupt output functionality to signal state changes to the host processor.
• Supports flexible output drive configurations including both open drain and push-pull modes.

Applications

• General purpose I/O expansion in embedded systems requiring additional digital control lines.
• Low voltage consumer electronics interfaces utilizing I2C communication protocols.
• Industrial control modules needing isolated or expanded digital input/output capabilities.

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel packaging quantity matches production requirements. Confirm that the TQFN55-32 footprint aligns with the target PCB design guidelines. Check RoHS compliance documentation for regulatory adherence in restricted substance environments. Ensure the I2C address configuration options meet system addressing constraints before finalizing procurement orders.

Selection Notes

Select this component when a high density of I/O pins is required within a compact surface mount package. The wide supply voltage range allows compatibility with various logic levels from 1.65 V to 5.5 V. Consider the interrupt feature if real-time response to input changes is necessary without constant polling. Verify that the 1 MHz clock speed meets the timing requirements of the master controller in the application circuit.

Part Context

This part belongs to the KTS1620 series of I/O expanders from Kinetic Technologies. The series focuses on low voltage operation and serial interface integration. Other variants in the family may offer different pin counts or package styles while maintaining similar interface characteristics. The ERG suffix typically denotes specific packaging and temperature grade specifications within the manufacturer's lineup.

Replacement Considerations

Direct substitutes must match the 24-bit I/O count, I2C interface, and TQFN55-32 package. Verify pin-to-pin compatibility and register mapping if replacing with other manufacturers' devices. Ensure equivalent voltage ranges and interrupt functionalities are present in any alternative components considered for the design.
