FST16232MEAX

Overview

The FST16232MEAX is a synchronous 16-bit to 32-bit multiplexer/demultiplexer bus switch manufactured by Fairchild Semiconductor. It belongs to the CBT/FST/QS/5C/B series and features CMOS technology with TTL compatibility. The device supports a supply voltage range of 4 V to 5.5 V, with a nominal rating of 5 V. It provides true output polarity and utilizes a die package form factor. The component integrates one functional unit with sixteen input lines and thirty-two output lines, terminated via fifty-six pins.

Feature Summary

• Enables connection between inputs and outputs without adding propagation delay or generating additional ground bounce noise.
• Allows two separate datapaths to be multiplexed onto or demultiplexed from a single path using synchronous control select pins.
• Provides low on-resistance for efficient signal transmission in flow-through mode.

Applications

• High-speed data routing in digital systems
• Multiplexing multiple data sources to a single destination
• Demultiplexing a single data source to multiple destinations

Procurement Notes

Verify the specific suffix MEAX against official Fairchild documentation to confirm pinout, packaging, and electrical characteristics match system requirements. Ensure the component meets RoHS compliance standards if required by the application. Cross-reference with ON Semiconductor resources as Fairchild has been integrated into their portfolio. Confirm availability status through authorized distributors.

Selection Notes

Select this component when synchronous 16-to-32 bit data routing is required with minimal signal distortion. The CMOS construction ensures compatibility with standard logic levels. Consider the die package format for board layout constraints. Verify that the 4 V to 5.5 V operating range aligns with the target power supply infrastructure.

Part Context

This part is part of the FST (Fast Switch Technology) family designed for high-speed applications. It serves as a bridge between different data paths in complex digital circuits. The synchronous nature allows precise timing control relative to the clock signal. It is distinct from asynchronous switches by its reliance on clock edges for state changes.

Replacement Considerations

Check for direct substitutes within the same FST series or compatible CMOS bus switches. Verify pin compatibility and electrical specifications before substitution. Consult ON Semiconductor cross-reference tools for equivalent parts.
