SN74CBTD3306PWR

Overview

The SN74CBTD3306PWR is a dual FET bus switch from Texas Instruments, featuring level shifting and -2 V undershoot protection. It operates on a single supply voltage ranging from 2.3 V to 3.6 V. The device provides two independent switches in an 8-pin TSSOP package. Key electrical parameters include a maximum on-resistance of 9 Ohms and a propagation delay of 200 ps at 5 V with 50 pF load. It supports output currents up to 128 mA and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates level shifting capability for interfacing between different voltage domains
• Includes built-in protection against signal undershoot down to -2 V
• Features low on-resistance for efficient signal transmission

Applications

• Portable equipment requiring voltage translation
• High-speed data buses
• Consumer electronics with mixed voltage logic

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-8 package and reel packaging configuration. Confirm RoHS compliance status and ensure the component matches the required operating voltage range of 2.3 V to 3.6 V for your design. Check for any recent product change notifications regarding manufacturing sites or materials.

Selection Notes

Select this component when level shifting and undershoot protection are required alongside low on-resistance. Compare against standard bus switches if voltage translation features are unnecessary. Ensure the TSSOP-8 package fits the PCB layout constraints and thermal requirements of the application.

Part Context

This part belongs to the SN74CBT series of high-speed CMOS bus switches. It is designed for applications requiring fast switching speeds and low power consumption. The device is manufactured by Texas Instruments and is part of their broader portfolio of logic and switching integrated circuits.
