SN74CBTD3306PW

Overview

The SN74CBTD3306PW is a dual FET bus switch IC from Texas Instruments, housed in an 8-pin TSSOP package. It operates with a supply voltage of 5 V and supports two bits of data switching. The device features a maximum on-resistance of 20 ohms and a propagation delay of up to 150 ps. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual FET bus switches for signal routing
• Includes level shifting capability for voltage translation
• Provides -2 V undershoot protection for input signals

Applications

• Portable equipment requiring low power consumption
• Consumer electronics utilizing high-speed data buses
• Computing systems needing efficient signal isolation

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-8 tube packaging configuration when ordering. Confirm that the lead time and availability align with current manufacturing schedules. Ensure the component meets RoHS compliance requirements for your specific assembly process. Cross-reference the datasheet revision to confirm pinout consistency.

Selection Notes

Select this component when a dual-channel bus switch with integrated level shifting is required. The TSSOP-8 package suits space-constrained surface-mount designs. Consider the 20-ohm on-resistance for signal integrity needs. Verify compatibility with the system's operating voltage and temperature range before integration.

Part Context

This part belongs to the SN74CBTD3306C series of digital bus switch ICs. It is functionally similar to variants like the SN74CBTD3306CDR but differs in package type. The series is designed for applications requiring fast switching speeds and low power dissipation in portable devices.

Replacement Considerations

The SN74CBTD3306CDR serves as a functional alternative with identical electrical characteristics but utilizes an SOIC-8 package instead of TSSOP-8. Ensure mechanical footprint compatibility before substitution.
