FSTUD16211MTDX

Overview

The FSTUD16211MTDX is a high-speed CMOS bus switch manufactured by Fairchild Semiconductor. It provides 24 bits of switching capability, organized as two independent 12-bit drivers with true outputs. The device is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP) with a body width of 6.10 mm. It operates within an industrial temperature range of -40 °C to +85 °C and is compliant with RoHS standards.

Feature Summary

• Provides 24 bits of high-speed CMOS TTL-compatible bus switching
• Features low on-resistance to support signal integrity
• Contains two independent 12-bit driver functions

Applications

• High-speed data bus isolation
• Signal routing in digital systems
• Level shifting between logic domains

Procurement Notes

Verify the manufacturer designation, as ON Semiconductor acquired Fairchild's semiconductor business. Confirm the package type is 56-TSSOP and check for lead-free compliance markings. Ensure the part number suffix matches the specific tape-and-reel configuration required for your assembly process.

Selection Notes

Select this component when a 24-bit wide bus switch is required for high-speed applications. The TSSOP-56 package is suitable for surface-mount assembly. Verify that the operating voltage and speed requirements align with the datasheet specifications before finalizing the design.

Part Context

This component belongs to the FSTUD series of bus switches. It serves as a logical interface element in digital circuits, allowing multiple devices to share a common bus while preventing contention. The dual 12-bit architecture enables flexible partitioning of data lines.

Replacement Considerations

The FSLV16211MTDX is listed as a related component with identical pin count and functional description. Verify electrical parameters and package dimensions before substitution.
