• Features pin-for-pin compatibility with QS3384, FST3384, and CBT3384 devices
• Operates with nearly zero standby current consumption
• Control inputs maintain compatibility with standard TTL and CMOS logic families

Applications

• High-speed data bus switching applications
• Portable battery-powered equipment requiring low power consumption
• Consumer electronics utilizing high-density signal routing
• Computing systems requiring fast bus transitions

Procurement Notes

Verify that the ordering suffix matches the required tape and reel specifications for automated assembly processes. Confirm the package type corresponds to the design footprint requirements. Ensure the operating temperature range aligns with the intended environmental conditions. Check for lead-free status if RoHS compliance is mandated for the final product assembly.

Selection Notes

Select this component when a high-channel count bus switch is required alongside strict power constraints. The wide supply voltage range supports various logic families without level shifting. Consider the package dimensions against available board space. Evaluate the on-resistance characteristics against the specific load capacitance and drive strength requirements of the target application circuit.
