FIN1047MTCX

Overview

The FIN1047MTCX is a quad driver designed for high-speed interconnects utilizing Low Voltage Differential Signaling (LVDS) technology. It translates LVTTL signal levels to LVDS levels with a typical differential output swing of 350mV, providing low EMI and ultra-low power dissipation even at high frequencies. The device supports data rates greater than 400 Mbps and features a flow-through pinout that simplifies PCB layout. It operates on a single 3.3V power supply and includes power-off protection. The component meets or exceeds the TIA/EIA-644 LVDS standard and is available in space-saving 16-Lead SOIC and TSSOP packages.

Feature Summary

• Translates LVTTL input signals to LVDS outputs for high-speed differential signaling applications
• Flow-through pinout architecture simplifies printed circuit board layout processes
• Includes power-off protection to prevent bus contention during system power cycles

Applications

• High-speed transfer of clock and data signals in digital systems
• Point-to-point or multi-drop interconnects requiring LVDS compliance
• Systems needing pin-compatible alternatives to RS-422 or LVPECL devices

Procurement Notes

Verify the specific suffix against the manufacturer's current nomenclature guidelines, as Fairchild Semiconductor integration may have altered ordering part numbers. Confirm package availability matches the required TSSOP or SOIC variant. Ensure the component source is an authorized distributor to guarantee authenticity and traceability for industrial or commercial deployment.

Selection Notes

Select this component when LVTTL to LVDS translation is required for high-speed data links. The flow-through design is optimal for minimizing trace length and skew in dense layouts. Verify that the 3.3V operating voltage aligns with the system power rails and that the 400 Mbps speed meets the application bandwidth requirements without necessitating faster, higher-cost alternatives.

Part Context

The FIN1047 belongs to the LVDS driver family originally developed by Fairchild Semiconductor, now managed by onsemi following their acquisition. It serves as the companion transmitter to receivers like the FIN1048. The 'MTC' suffix denotes the Thin Shrink Small Outline Package (TSSOP), while 'X' typically indicates tape and reel packaging for automated assembly.

Replacement Considerations

Direct pin-compatible replacements include other LVDS quad drivers from major manufacturers such as TI or NXP, provided they meet the 3.3V requirement and TIA/EIA-644 standard. Verify electrical parameters like propagation delay and output swing before substitution.
