FSTD16861MTDX

Overview

The FSTD16861MTDX is a 20-bit bus switch with level shifting capabilities manufactured by onsemi. It integrates ten independent single-pole single-throw (SPST) switches, providing a 10 x 1:1 circuit configuration within a compact 48-TSSOP package. This component facilitates signal routing and voltage translation between different logic domains in high-density electronic systems.

Feature Summary

• Integrates ten independent SPST switches for flexible signal routing
• Provides built-in level shifting to translate signals between different voltage domains
• Designed for high-density applications requiring minimal board space

Applications

• High-speed data bus switching in consumer electronics
• Voltage level translation in industrial control systems
• Signal routing in automotive infotainment interfaces

Procurement Notes

Verify the specific ordering suffix MTDX to ensure correct packaging and tape-and-reel specifications. Confirm that the obsolete status does not impact long-term supply requirements for your design lifecycle. Cross-reference the 48-TSSOP footprint dimensions during PCB layout finalization to ensure mechanical compatibility.

Selection Notes

Select this component when designing circuits requiring simultaneous switching of multiple bidirectional lines with voltage domain translation. The 10-channel architecture reduces component count compared to discrete solutions. Ensure input voltage levels align with the device's specified operating range to maintain signal integrity across all channels.

Part Context

This part belongs to onsemi's standard logic and signal switch portfolio, categorized under interface and timing components. It serves as a specialized solution for managing complex signal paths in mixed-voltage environments, complementing broader families of bus switches and multiplexers offered by the manufacturer.
