FSTU3384WMX

Overview

The FSTU3384WMX is a high-speed, low-voltage CMOS bus driver manufactured by Fairchild Semiconductor. It belongs to the CBT/FST/QS/5C/B series and features a 10-bit configuration with true outputs. The device is housed in a TSSOP-24 package (MO-153) with a width of 4.40 mm. It operates as a TTL-compatible bus switch designed for efficient data transmission in digital systems.

Feature Summary

• Provides bidirectional or unidirectional buffering for digital signals
• Features low on-resistance for minimal signal attenuation
• Supports high-speed data transfer rates suitable for modern interfaces

Applications

• Memory interface circuits
• Microprocessor system buses
• Communication equipment signal routing

Procurement Notes

Verify the exact part number spelling, as nomenclature changes may occur during corporate transitions. Confirm package details match the required MO-153 specification. Ensure compliance with current RoHS standards before procurement. Cross-reference ordering information with the official manufacturer website for accuracy.

Selection Notes

Select this component when a 10-bit bus driver with true output polarity is required. The TSSOP-24 package offers a compact footprint for space-constrained designs. Verify voltage compatibility with the target system logic levels. Consider thermal performance requirements for the specific application environment.

Part Context

Fairchild Semiconductor was acquired by ON Semiconductor. Part numbers originally containing underscores may have been updated to use dashes in new manufacturing systems. This component represents legacy inventory from the Fairchild product line now managed under the ON Semiconductor portfolio.

Replacement Considerations

Check for updated part numbers using dash notation instead of underscores. Verify pinout compatibility with existing board layouts. Confirm electrical specifications match the original design requirements.
