FST3384WMX

Overview

The FST3384WMX is a 10-bit bus switch manufactured by Fairchild Semiconductor, belonging to the CBT/FST/QS/5C/B series. It features true output configuration and operates within a single supply voltage range of 1.65V to 3.6V. The device is housed in a 24-pin TSSOP package with a maximum operating temperature of 85°C. Designed for low power applications, it provides TTL-compatible bus switching capabilities with high-speed data transmission performance suitable for portable electronics and communication systems.

Feature Summary

• Provides 10-bit bidirectional bus switching functionality
• Operates with low supply voltage ranging from 1.65V to 3.6V
• Features TTL-compatible input logic levels
• Utilizes a compact 24-pin TSSOP surface-mount package

Applications

• Portable consumer electronics such as mobile phones and PDAs
• Communication equipment requiring high-speed data transfer
• Computer peripherals and motherboard interconnects
• Battery-powered devices needing low power consumption

Procurement Notes

Verify the manufacturer marking on the component body to confirm Fairchild Semiconductor origin. Ensure the part number suffix matches WMX for the specific tape-and-reel packaging variant. Check for RoHS compliance markings if environmental regulations are required. Confirm the pinout orientation against the official datasheet before integration into PCB designs to avoid connection errors.

Selection Notes

Select this component when a 10-bit wide bus interface is required within tight space constraints. The low voltage operation makes it suitable for modern battery-operated devices. Consider the TSSOP package size for assembly compatibility. Verify that the signal speeds required by the application fall within the specified performance limits of the FST series technology.

Part Context

This component is part of the broader FST (Fast Switching Technology) family developed by Fairchild Semiconductor. These switches are designed to replace traditional CMOS bus switches with faster switching speeds and lower power consumption. The FST3384 specifically addresses the need for high-density data routing in compact electronic systems.

Replacement Considerations

Compatible substitutes include the ON Semiconductor FST3384MTCX and other variants within the same FST3384 product line. Ensure any replacement maintains the same 24-pin TSSOP footprint and electrical characteristics. Verify that alternative sources offer equivalent switching speed and voltage tolerance specifications.
