SN74TVC3306DCTRE4

Specialty Logic Overview

The SN74TVC3306DCTRE4 is a dual FET bus switch from Texas Instruments, featuring level shifting and -2 V undershoot protection. It operates within a supply voltage range of 1.65 V to 3.6 V. The device provides a maximum on-resistance of 16.5 Ohms and a maximum propagation delay of 1.4 ns. It is housed in an 8-pin VSSOP package with dimensions of 3x2 mm. The component supports an operating temperature range from -40 °C to +85 °C.

Specialty Logic Feature Summary

• Integrates voltage clamps for ESD protection on all ports
• Provides level shifting capability between different voltage domains
• Includes -2 V undershoot protection for signal integrity

Specialty Logic Applications

• Portable equipment requiring low-voltage operation
• Consumer electronics with mixed voltage interfaces
• Computing and peripheral devices

Specialty Logic Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status. Confirm the 'DCTR' package code corresponds to the VSSOP-8 form factor. Ensure the ordering part number matches the exact pinout and electrical specifications required for the design.

Specialty Logic Selection Notes

Select this component when bidirectional level shifting is required between 1.65 V and 3.6 V domains. Consider the 16.5 Ohm on-resistance for bandwidth requirements. Verify that the VSSOP-8 package fits the PCB layout constraints compared to SOIC alternatives.

Specialty Logic Part Context

This part belongs to the SN74TVC3306 family of dual bus switches. It shares functional similarities with the SN74CBTD3306 but includes integrated voltage clamps for enhanced ESD protection. The device is designed for applications needing high-speed data transfer with robust signal conditioning.

Specialty Logic Replacement Considerations

SN74CBTD3306DCTR: Similar functionality but lacks integrated voltage clamps. SN74CBTS3306DCTR: Different logic family with potentially different drive characteristics.
