74CB3T3306DCURG4

Overview

The SN74CB3T3306DCURG4 is a dual bus switch from Texas Instruments' CB3T series, housed in an 8-VSSOP package. It operates on a single supply voltage ranging from 2.3 V to 3.6 V and supports a wide operating temperature range of -40 °C to +85 °C. The device features two independent bidirectional switches with low on-resistance and controlled turn-on speeds to minimize signal reflections.

Feature Summary

• Dual bidirectional bus switching architecture for efficient signal routing
• Controlled turn-on speed design to reduce high-frequency ringing and ground bounce
• Low on-resistance characteristic ensuring minimal signal attenuation

Applications

• Portable equipment requiring low-voltage signal switching
• Consumer electronics utilizing 3.3 V logic interfaces
• Computing modules needing bidirectional data path management

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package marking matches the 8-VSSOP outline drawing. Ensure the ordering part number aligns with the required tape-and-reel quantity specifications for manufacturing integration.

Selection Notes

Select this component when designing systems that require bidirectional switching between 2.3 V and 3.6 V domains. The controlled slew rate makes it suitable for high-speed digital buses where signal integrity is critical. Compare against standard CBT variants if fixed turn-on speed is not required or if different voltage levels are needed.

Part Context

This device belongs to the SN74CB3T family of low-voltage bus switches. It shares functional similarities with the SN74CB3Q3306A but differs in operating voltage ranges and specific electrical characteristics. The DCUR suffix denotes the surface-mount VSSOP-8 package variant within the broader 74CB3T3306 product line.
