74FST3383DTR2

Overview

The onsemi 74FST3383DTR2 is a 10-bit low power bus exchange device operating between 4.0 and 5.5 volts. It features CMOS TTL compatibility, extremely low RON of 4 ohms typical, and nearly zero propagation delay through the switch. The component adds no noise or ground bounce to the system, with control inputs compatible with TTL/CMOS logic levels.

Feature Summary

• Provides 10-bit bus exchange functionality with minimal signal distortion
• Operates with nearly zero standby current consumption
• Ensures circuit stability by eliminating circuit bounce effects
• Features pin-for-pin compatibility with QS3383, FST3383, and CBT3383

Applications

• High-speed data routing in digital communication systems
• Signal path switching in computer peripheral interfaces
• Bus isolation and exchange in industrial control networks

Procurement Notes

Verify that the ordering suffix DTR2 corresponds specifically to the TSSOP-24 package configuration as documented in the official datasheet. Confirm that the component meets RoHS standards and Pb-Free requirements for the specific manufacturing lot before integration into final assemblies.

Selection Notes

Select this component when designing circuits requiring low power dissipation and high-speed bus exchange capabilities within the 4V to 5.5V supply range. Ensure that the application environment remains within the specified -40°C to +85°C operating temperature limits to maintain optimal performance and reliability.

Part Context

This part belongs to the 74FST series of high-speed bus switches manufactured by onsemi. It is designed to replace older generation bus exchange components while offering improved electrical characteristics such as lower on-resistance and reduced propagation delay for modern high-frequency applications.

Replacement Considerations

The datasheet confirms pin-for-pin compatibility with the QS3383, FST3383, and CBT3383 devices. These parts can be used as direct substitutes without requiring schematic modifications.
