74FST3384DTR2

Overview

The onsemi 74FST3384DTR2G is a 10-bit low power bus switch manufactured by Semiconductor Components Industries, LLC. It operates within a supply voltage range of 4.0 V to 5.5 V and features CMOS/TTL compatible control inputs. The device provides two independent enable pins (OE1, OE2) that allow for segmented switching of the ten bidirectional data lines. It exhibits extremely low on-resistance and nearly zero propagation delay, ensuring signal integrity without adding noise or ground bounce to the system.

Feature Summary

• Provides bidirectional data transmission with minimal insertion loss due to low on-resistance characteristics
• Features dual independent control inputs allowing flexible segmentation of the ten data channels
• Maintains high signal fidelity by eliminating circuit bounce and minimizing propagation delay

Applications

• High-speed data bus bridging in computer systems
• Level shifting between different logic families in mixed-voltage environments
• Signal routing in telecommunications equipment requiring low latency

Procurement Notes

Verify the specific package suffix matches the required form factor, as the DTR2G designation indicates a TSSOP-24 tape and reel configuration. Confirm RoHS compliance status and lead-free soldering requirements against project specifications. Ensure ordering documentation references the correct revision level to guarantee compatibility with existing design files and manufacturing processes.

Selection Notes

Select this component when designing circuits that require low-latency signal routing across multiple data lines simultaneously. The dual-enable architecture offers greater flexibility compared to single-enable alternatives. Verify that the operating voltage aligns with the 4.0 V to 5.5 V specification to ensure proper functionality and avoid exceeding maximum ratings during operation.

Part Context

This component belongs to the FST series of bus switches designed for high-performance digital applications. It serves as a direct pin-for-pin replacement for several competing industry-standard devices, facilitating easier upgrades or cross-manufacturer sourcing strategies without necessitating significant PCB layout modifications.

Replacement Considerations

Direct substitutes include the QS3384, FST3384, and CBT3384. These components share identical pinouts and functional characteristics, allowing for drop-in replacements in existing designs.
