FST16213MEA

Overview

The FST16213MEA is a high-speed CMOS bus switch manufactured by Fairchild Semiconductor, belonging to the FST series. It functions as a 16-bit multiplexer/demultiplexer with true outputs and operates in a 54-pin FBGA package (MO-205). The device supports a wide operating temperature range from -40 °C to +85 °C and features three-state outputs. It is designed for low on-resistance switching applications, ensuring minimal propagation delay and ground bounce noise while maintaining TTL-compatible control input levels.

Feature Summary

• Provides high-speed signal routing through a 16-bit multiplexer/demultiplexer architecture
• Features low on-resistance to minimize propagation delay and ground bounce noise
• Supports zero bounce operation in flow-through mode for reliable data transfer
• Maintains compatibility with TTL logic levels for control inputs

Applications

• High-speed data bus switching in digital systems
• Multiplexing and demultiplexing signals in communication interfaces
• Signal routing in consumer electronics requiring low latency
• Board-to-board interconnects in industrial equipment

Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor assets are now managed by ON Semiconductor. Confirm that the 'MEA' suffix denotes the correct plastic FBGA-54 package variant. Ensure compliance documentation matches the required RoHS standards for your region. Cross-reference the datasheet revision date to confirm technical specifications have not changed since the original Fairchild publication.

Selection Notes

Select this component when a 16-bit bidirectional bus switch is required with minimal signal distortion. The FBGA-54 package suits space-constrained designs needing high pin density. Consider the -40 °C to +85 °C range against environmental conditions. Verify that the 4Ω typical on-resistance meets the voltage drop requirements of the target application circuit.

Part Context

This part belongs to the FST (Fast Switch Technology) family, characterized by high speed and low power consumption. It serves as a direct replacement for older CBT or 5C series drivers in modern high-density layouts. The device integrates multiple switches into a single IC, reducing board space compared to discrete solutions. Its CMOS technology ensures low static power dissipation during steady states.

Replacement Considerations

Check for equivalents such as the FSTD16211GX or FST16233 within the same product family. Verify pinout compatibility before substitution, as package variations may exist. Ensure the substitute maintains the same 54-pin FBGA footprint and electrical characteristics for seamless integration.
