74FST6800DWR2

Overview

The onsemi 74FST6800DWR2 is a 10-bit bus switch with precharged outputs, designed for high-speed data routing. It operates within a supply voltage range of 4.0 V to 5.5 V and features extremely low on-resistance (RON) and nearly zero propagation delay. The device exhibits negligible standby current and prevents circuit bounce or ground noise. Control inputs are compatible with both TTL and CMOS logic levels. It is available in SOIC-24 surface-mount packages.

Feature Summary

• Features precharged outputs that provide extremely low on-resistance and minimal propagation delay.
• Operates with nearly zero standby current and eliminates circuit bounce or ground noise.
• Control inputs maintain compatibility with standard TTL and CMOS logic families.

Applications

• High-speed data routing in digital systems
• Bus switching applications requiring low signal distortion
• Portable equipment utilizing battery-powered logic

Procurement Notes

Verify the specific suffix 'DWR2' corresponds to the SOIC-24 package configuration and tape-and-reel shipping format. Confirm the component meets RoHS standards as indicated by the manufacturer's documentation. Ensure the ordering number matches the exact pinout and electrical specifications required for the target design.

Selection Notes

Select this component when designing circuits that require bidirectional data transfer with minimal signal degradation. The FST series technology supports operation at higher frequencies compared to standard logic families. Consider the 10-bit width for parallel data buses and verify that the operating voltage aligns with the system's power supply rails.

Part Context
