FST6800WM

Overview

The FST6800WM is a 10-bit bus switch manufactured by Fairchild Semiconductor, housed in a 24-lead Small Outline Integrated Circuit (SOIC) package. It operates on a single supply voltage ranging from 4V to 5.5V. The device provides high-speed CMOS TTL-compatible interfaces with precharged outputs to minimize switching noise.

Feature Summary

• Provides ten bits of high-speed signal routing capability
• Features precharged outputs for reduced switching transients
• Supports TTL-compatible logic levels

Applications

• High-speed data bus isolation
• TTL-to-CMOS interface bridging
• Signal path selection in digital systems

Procurement Notes

Verify the manufacturer designation and package type against official documentation. Confirm that the component matches the specified 24-lead SOIC form factor. Ensure the part number corresponds to the original Fairchild Semiconductor production line before integration into designs.

Selection Notes

Select this component when a multi-channel bus switch with precharged output characteristics is required. It is suitable for applications needing isolated bidirectional data paths within standard TTL voltage ranges. Verify pin compatibility and thermal requirements for the specific PCB layout.

Part Context

This component belongs to the FST series of bus switches designed for high-speed digital applications. The WM suffix indicates the specific 24-lead SOIC packaging variant. It serves as a signal routing solution for managing multiple data lines simultaneously.

Replacement Considerations

The FST6800MTCX is a documented equivalent part number offering identical functional specifications. Verify package dimensions and pinout alignment before substitution.
