SN74CBT3306DRG4

Overview

The SN74CBT3306DRG4 is a dual bus switch from Texas Instruments' CBT logic family, housed in an 8-pin SOIC package. It operates on a single supply voltage ranging from 2.5 V to 3.6 V. The device features two independent switches with low on-resistance of 10 ohms and propagation delay of 0.9 ns at 3.3 V. It supports bidirectional data transfer with configurable control inputs and includes overvoltage tolerance up to 3.6 V on I/O lines while powered down.

Feature Summary

• Dual FET bus switch architecture providing two independent signal paths
• Low on-resistance for minimal signal attenuation across the channel
• Configurable control inputs allowing flexible switching logic integration
• Overvoltage protection on I/O pins ensuring safe operation during power-down states

Applications

• Portable equipment requiring low-voltage signal routing
• Consumer electronics utilizing high-speed data buses
• Communication systems needing isolated signal paths
• Industrial control modules managing multiple sensor interfaces

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the datasheet revision date to guarantee compatibility with current design standards.

Selection Notes

Select this component when designing circuits that require low-voltage operation between 2.5 V and 3.6 V. The low on-resistance makes it suitable for applications demanding high signal integrity. Consider the package size constraints if space is limited within the enclosure. Evaluate the control input configuration needs against available GPIO resources on the host processor.

Part Context

This part belongs to the SN74CBT series of bus switches designed for low-voltage applications. It serves as a digital switch alternative to mechanical relays or other solid-state switches. The device integrates level-shifting capabilities to interface between different voltage domains efficiently.

Replacement Considerations

SN74CBT3306D: Identical electrical characteristics but without the G4 lead-free suffix. SN74CBT3306DR: Same function and package, standard reel packaging variant. SN74CBT3306DBV: Different VSSOP-8 package option for space-constrained designs.
