• Provides twenty bits of high-speed CMOS bus switching functionality
• Features low on-resistance for efficient signal path conduction
• Supports TTL-compatible logic levels for broad interface integration

Applications

• High-speed data bus isolation in digital systems
• Signal routing between different voltage domains
• Portable equipment requiring compact switching solutions

Procurement Notes

Verify the manufacturer designation, as ON Semiconductor acquired Fairchild Semiconductor's operations. Confirm the specific package type and pin configuration match the design requirements. Check for RoHS compliance status if environmental regulations apply to the target market. Ensure the component lifecycle status aligns with long-term production needs.

Selection Notes

Select this component when twenty isolated bidirectional channels are required within a single integrated circuit. The 48-pin TSSOP package offers a balance between pin count and physical footprint. Consider the low on-resistance specification for applications demanding minimal signal attenuation across the switch.

Part Context

This part belongs to the FST series of fast bus switches designed for high-performance digital applications. The series typically features CMOS technology compatible with standard logic families. The MTDX suffix indicates the specific tape-and-reel packaging format used for automated assembly processes.

Replacement Considerations

Consult official cross-reference lists from ON Semiconductor for verified substitutes. Verify pin compatibility and electrical specifications before substituting. Generic equivalents may not match the exact switching speed or on-resistance characteristics.
