74FST6800DW

Overview

The onsemi 74FST6800DW is a high-performance bus switch designed for data routing applications. It features ten independent 1-to-1 switches, providing flexible signal path configuration. The device operates within a supply voltage range of 4.5V to 5.5V and supports both ECL and TTL input logic levels. It utilizes a 24-SOIC surface-mount package with a J-leaded variant available. The component is rated for an operating temperature range of -40°C to +85°C and has a maximum frequency capability of 100MHz.

Feature Summary

• Provides ten independent single-pole single-throw (SPST) switching paths for versatile data routing
• Supports differential signaling inputs and outputs for high-speed signal integrity
• Compatible with both ECL and TTL logic families for broad system integration

Applications

• High-speed data bus switching in communication systems
• Signal routing for microprocessor units requiring low latency
• Multiplexing applications in digital logic circuits

Procurement Notes

Verify the specific suffix 'DW' against the manufacturer's current datasheet to confirm the exact package dimensions and tape-and-reel specifications. Confirm RoHS compliance status as historical records indicate variations within this product family. Ensure the ordering part number matches the required lead-free or standard tin-lead finish requirements for your assembly process.

Selection Notes

Select this component when designing systems requiring multiple isolated signal paths with minimal insertion loss. The 10-channel configuration offers higher density than single-switch alternatives. Verify that the 5V supply rail aligns with the target logic levels. Consider the SOIC package footprint constraints during PCB layout to ensure adequate clearance for the 24-pin body.

Part Context

This part belongs to the FST (Fast Switching Technology) series from onsemi, optimized for high-speed digital applications. It serves as a bus switch solution, distinct from multiplexers or decoders by offering direct pass-through control. The family is characterized by low on-resistance and fast switching speeds suitable for modern digital interfaces.

Replacement Considerations

Direct substitutes include the SN74CBTS6800DWR from Texas Instruments, which shares similar channel counts and package types. Verify pin compatibility and electrical characteristics before substitution.
