FST16233MTDX

Overview

The FST16233MTDX is a high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch manufactured by Fairchild Semiconductor. It functions as a 16-bit to 32-bit data path selector, allowing inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. The device features a low on-resistance of 4Ω between ports and includes control inputs compatible with TTL levels. It operates within a supply voltage range of 4V to 5.5V, with a nominal voltage of 5V. The component is housed in an uncase chip die package.

Feature Summary

• Provides synchronous multiplexing and demultiplexing capabilities for two separate datapaths onto a single path using clocked control select pins.
• Maintains signal integrity by eliminating propagation delay and preventing ground bounce noise during switching operations.
• Ensures zero bounce behavior when operating in flow-through mode.

Applications

• High-speed data routing in digital communication systems
• Bus switching applications requiring minimal signal distortion
• Multiplexing multiple data sources into a single output channel

Procurement Notes

Verify the specific suffix 'MTDX' against official Fairchild documentation to confirm exact tape-and-reel specifications and handling requirements. Ensure compatibility with standard CMOS logic families and validate that the 4V to 5.5V operating range aligns with target system power rails. Confirm RoHS compliance status through current manufacturer declarations.

Selection Notes

Select this component for designs requiring fast, low-distortion signal routing between 16-bit input and 32-bit output configurations. The TTL-compatible control inputs simplify interface design with standard logic controllers. Consider the die package format for appropriate PCB mounting and thermal management strategies.
