FSTD16211MTD

Overview

The FSTD16211MTD is a bus switch manufactured by onsemi, designed for high-speed signal routing applications. It features a configuration of twelve independent 1-to-1 switches, providing a total of twenty-four bits of data path capability within a single integrated circuit. The device operates on a single power supply source with a specified voltage range extending from 4.5 volts to 5.5 volts. It is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP), which measures approximately 6.10 millimeters in width. The component supports surface mount installation and is rated for an operating temperature range spanning from negative forty degrees Celsius to positive eighty-five degrees Celsius.

Feature Summary

• Integrates twelve independent bidirectional channels for flexible signal routing
• Supports low-voltage digital logic families through wide supply voltage compatibility
• Utilizes a compact surface-mount package optimized for high-density board layouts

Applications

• High-speed data bus switching in computing systems
• Signal multiplexing in consumer electronics interfaces
• Data line protection and isolation in industrial control modules

Procurement Notes

Verify the specific suffix designation against current manufacturer documentation, as the MTDX variant indicates end-of-life status. Confirm that the selected replacement part maintains identical pinout and electrical characteristics to ensure seamless integration into existing designs without requiring schematic modifications.

Selection Notes

Select this component when designing circuits requiring multiple isolated signal paths within a constrained footprint. Ensure the system power supply remains stable within the specified voltage limits to maintain signal integrity. Consider the thermal performance of the TSSOP package if the application involves continuous high-frequency switching operations or elevated ambient temperatures.

Part Context

This device belongs to the FSTD series of bus switches, which are engineered for efficient data transfer in digital systems. The series offers various configurations to accommodate different channel counts and package types. This specific model provides a balanced solution for applications needing moderate channel density with standard voltage levels.

Replacement Considerations

The SN74CBTD16211 is identified as a direct substitute available from Texas Instruments. Verify functional equivalence regarding pin assignment and electrical specifications before implementation.
