Overview
The FST3384QSCX is a 10-bit low power bus switch manufactured by onsemi, housed in a 24-lead Quarter Size Outline Package (QSOP). It provides high-speed CMOS and TTL-compatible switching with an on-resistance of 4Ω. The device features two independent 5-bit switches controlled by separate OE signals. Operating conditions include a supply voltage range of 4.0V to 5.5V and a free air operating temperature from -40°C to +85°C.
Feature Summary
- Ultra-low quiescent current consumption
- Zero ground bounce noise in flow-through mode
- Minimal propagation delay through the switch
- Control inputs compatible with TTL levels
Applications
- High-speed data bus switching
- Portable battery-powered applications
- Consumer electronics
- Communications equipment
Procurement Notes
Verify the specific package type QSOP against system requirements. Confirm that the ordering suffix 'X' indicates tape and reel packaging if required for automated assembly. Ensure compatibility with the intended supply voltage range and temperature specifications before finalizing procurement.
Selection Notes
Select this component when low power consumption and minimal signal distortion are critical. The dual 5-bit configuration allows flexible routing of parallel data lines. Verify that the package dimensions fit the available PCB space and that the thermal characteristics meet the application's operational environment constraints.
Part Context
This part belongs to the FST series of bus switches, designed for high-speed data transfer applications. It represents a transition from Fairchild Semiconductor products into the onsemi portfolio following corporate integration. The technology maintains proven switch performance while adapting to modern manufacturing standards.
Replacement Considerations
Check for updated part numbers due to the integration of Fairchild Semiconductor into onsemi. Verify pinout and electrical characteristics against any legacy equivalents to ensure functional compatibility without redesigning the circuit board.
