SN74CBT3306CPWRG4

Overview

The SN74CBT3306CPWRG4 is a dual bus switch manufactured by Texas Instruments, belonging to the SN74CBT3306 series. It features two independent 1:1 switches housed in an 8-TSSOP package. The device operates within a supply voltage range of 2.3V to 3.6V and supports signal levels from 1.2V to 3.6V. Key electrical specifications include a maximum on-resistance of 16 ohms and a propagation delay of 1.4 nanoseconds. It functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides two independent bidirectional channels for low-voltage signal routing
• Supports simultaneous translation between different voltage domains
• Offers low on-resistance for minimal signal attenuation
• Features fast switching speeds suitable for high-frequency data lines

Applications

• Portable equipment requiring multiple voltage domain interfaces
• Consumer electronics with mixed-signal architectures
• Industrial control systems utilizing low-voltage logic
• Communications equipment managing diverse signal standards

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the 'C' designation aligns with commercial temperature ratings. Ensure the 8-TSSOP footprint matches the target PCB layout constraints. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential design changes affecting pin compatibility or electrical characteristics.

Selection Notes

Select this component when designing circuits requiring dual-channel isolation between distinct voltage domains. It is appropriate for applications needing low insertion loss and fast switching times. Consider the 8-TSSOP package size for space-constrained designs. Evaluate the 2.3V to 3.6V operating range against the system's power supply rails to ensure proper functionality under all expected load conditions.

Part Context

This part belongs to the Texas Instruments SN74CBT3306 family of dual bus switches. These devices are engineered for low-voltage applications, offering efficient signal path management. The family is designed to replace discrete transistor solutions, providing integrated protection and switching capabilities in a compact surface-mount package suitable for modern electronic assemblies.

Replacement Considerations

Check for SN74CBT3306D variants if SOIC packaging is required instead of TSSOP. Verify SN74CBT3306PWR for standard reel configurations. Consult official substitution lists for updated revisions ensuring identical pinout and electrical performance.
