FST16292MEAX

Overview

The FST16292MEAX is a synchronous 9-bit to 18-bit multiplexer/demultiplexer bus switch manufactured by Fairchild Semiconductor. It belongs to the CBT/FST/QS/5C/B series and utilizes CMOS technology compatible with TTL logic levels. The device features a single function block with 9 input lines and 18 output lines, providing true output polarity. It operates within a supply voltage range of 4 V to 5.5 V, with a nominal voltage of 5 V. The component is designed for high-speed data path switching applications requiring minimal propagation delay.

Feature Summary

• Synchronous multiplexing capability allowing inputs to connect to outputs without adding propagation delay or generating additional ground bounce noise
• Supports two separate datapaths that can be multiplexed onto or demultiplexed from a single path via control select pins
• CMOS construction ensuring low power consumption (Icc) and zero bounce in flow-through mode

Applications

• High-speed data path switching in digital systems
• Multiplexing multiple data sources onto a single transmission line
• Demultiplexing a single data source to multiple destinations

Procurement Notes

Verify the specific package designation corresponding to the 'MEA' suffix against official Fairchild documentation, as generic listings may not define the exact physical footprint. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are not present in the provided technical overview. Ensure the ordering part number matches the required pin configuration and electrical specifications for the target application.

Selection Notes

Select this component when a synchronous 9-to-18 bit bus switching solution is required for 5V logic systems. The device is suitable for designs needing minimal signal distortion and low power dissipation. Consider the operating voltage range of 4V to 5.5V and the CMOS/TTL compatibility when integrating with other system components. Verify that the package type associated with the MEA suffix meets the board layout requirements.

Part Context

The FST16292MEAX is part of the broader FST/CBT series of bus switches produced by Fairchild Semiconductor. This family of devices is characterized by high-speed operation and low on-resistance, making them suitable for various digital communication interfaces. The specific model provides a 9-bit to 18-bit configuration, distinguishing it from other variants in the series that may offer different input/output ratios.

Replacement Considerations

Compatible substitutes include other synchronous bus switches from the same CBT/FST series with matching 9-to-18 bit configurations and 5V operation. Verify pinout compatibility and electrical parameters such as on-resistance and propagation delay before substitution.
