SN74CBT3306PWRE4

Overview

The SN74CBT3306PWRE4 is a dual FET bus switch from the Texas Instruments CBT logic series, housed in an 8-TSSOP package. It features a 1 x 1:1 configuration with two independent circuits. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40 °C to +85 °C. Key electrical parameters include a maximum on-resistance of 12 ohms and a maximum propagation delay of 150 ps at 5 V with a 50 pF load. Output drive capabilities are specified as -128 mA for high-level and 128 mA for low-level currents.

Feature Summary

• Dual FET architecture providing two independent bidirectional switching paths
• Low on-resistance characteristic ensuring minimal signal attenuation
• High bandwidth capability suitable for fast digital signal transmission
• Compliant with RoHS Directive and Green Product standards

Applications

• Portable equipment requiring efficient power management
• Consumer electronics utilizing high-speed data buses
• Computing systems involving peripheral interconnects
• Telecommunications infrastructure components

Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free status and environmental compliance. Ensure the TSSOP-8 package variant matches the target PCB footprint design. Cross-reference the specific revision level against current datasheets to validate pinout compatibility and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel solution is required for 5 V logic interfaces. The low on-resistance makes it suitable for applications demanding high signal integrity. Consider the TSSOP-8 package constraints regarding thermal dissipation and board space. Verify that the input voltage levels align with the source logic family to ensure proper switching thresholds.

Part Context

This device belongs to the SN74CBT3306C family of digital bus switches. The E4 suffix indicates a lead-free and environmentally friendly manufacturing process compliant with international standards. It serves as a replacement or alternative for standard plastic packages in surface-mount designs requiring compact form factors.

Replacement Considerations

SN74CBT3306PWR is the non-E4 equivalent offering identical electrical performance without the specific environmental suffix designation.
