KTS1620EWA-TR

Overview

The KTS1620EWA-TR is a low voltage 24-bit I/O expander designed for microcontroller applications requiring additional I/O with minimal interconnections. It operates on the I2C-bus interface and supports a maximum clock frequency of 1 MHz. The device functions within an operating supply voltage range of 1.65 V to 5.5 V. It features open-drain outputs and includes interrupt output capabilities. The component is housed in a 36-FOWLP (2.6x2.6) package, suitable for surface mount installation.

Feature Summary

• Provides 24 general-purpose I/O expansion via standard I2C communication
• Supports interrupt-driven operation for efficient host monitoring
• Compatible with low voltage logic levels from 1.65 V to 5.5 V

Applications

• Microcontroller systems requiring extended I/O ports
• Low voltage embedded control interfaces
• Portable electronic devices with space constraints

Procurement Notes

Verify the specific suffix EWA against official Kinetic Technologies documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with the target I2C bus speed and voltage levels before integration. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status.

Selection Notes

Select this component when a high density of I/O pins is required in a compact footprint. The 24-bit capacity reduces pin count on the main processor compared to parallel expanders. Verify that the system design accommodates the 1 MHz I2C clock limit and utilizes the interrupt feature for optimal performance.

Part Context

This model belongs to the Kinetic Technologies I/O expander family, specifically engineered for low-voltage digital interfacing. It serves as a bridge between microcontrollers and peripheral devices, expanding connectivity without complex wiring. The FOWLP packaging supports high-density PCB layouts common in modern consumer electronics.

Replacement Considerations

Consult official Kinetic Technologies substitution guides for verified alternative part numbers. Generic I/O expanders may not match the specific voltage ranges or interrupt functionalities. Do not assume pin-to-pin compatibility with other manufacturers' components without explicit datasheet confirmation.
