SN74CBT3384APW

Overview

The SN74CBT3384APW is an octal bus switch manufactured by Texas Instruments, designed for high-speed data routing in digital systems. It operates within a supply voltage range of 2.7 V to 3.6 V and features low on-resistance to minimize signal attenuation. The device includes three-state outputs and is housed in a TSSOP-20 package suitable for surface-mount applications. It supports bidirectional data transfer with independent control lines for each channel pair.

Feature Summary

• Octal configuration providing eight independent bidirectional channels for flexible data path management
• Low on-resistance characteristic ensures minimal insertion loss and maintains signal integrity across the bus
• Three-state output capability allows multiple switches to share a common bus without electrical conflict
• Compatible with standard logic families operating at 3.3 V nominal supply voltages

Applications

• High-speed data routing in portable consumer electronics
• Signal switching in industrial control systems requiring low power consumption
• Bus expansion interfaces in computing hardware
• Memory card slot selection circuits

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeits. Confirm RoHS compliance status matches specific project requirements. Check datasheet revisions for any pinout or electrical parameter updates before finalizing design integration. Ensure storage conditions adhere to moisture sensitivity level specifications to prevent package damage during soldering.

Selection Notes

Select this component when designing systems requiring multiple isolated data paths controlled by separate enable signals. Compare propagation delay specifications against system timing constraints to ensure signal coherence. Evaluate power dissipation limits under maximum load conditions to determine adequate thermal management strategies. Consider package availability and lead times relative to production schedules.
