SN74CB3T3384PWR

Overview

The SN74CB3T3384PWR is a digital bus switch IC from Texas Instruments, featuring an octal buffer/driver configuration with three-state outputs. It operates within a supply voltage range of 2.3 V to 3.6 V and supports a maximum operating temperature of +85 °C. The device utilizes a TSSOP-24 surface-mount package. Key electrical characteristics include a maximum on-resistance of 5 Ohms and a maximum propagation delay of 250 ps. It is designed for low-voltage applications requiring efficient signal path translation.

Feature Summary

• Provides bidirectional data transmission across eight independent channels
• Supports level shifting between 2.5-V and 3.3-V logic systems
• Includes 5-V tolerant inputs for safe interfacing with higher voltage domains
• Offers powered-off protection to prevent excessive current draw during power-down states

Applications

• Mobile phone and handheld equipment internal buses
• Consumer electronics requiring low-voltage signal switching
• Portable computing devices and peripherals
• Industrial control systems utilizing mixed-voltage logic interfaces

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-24 reel packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the component meets automotive or industrial qualification requirements if applicable to the end-use environment by checking the specific datasheet revision.

Selection Notes

Select this component for designs requiring high-speed switching with minimal signal distortion in low-voltage environments. The integrated level shifter simplifies interface design between different voltage domains without external components. Consider the 5-V tolerance feature for robustness against voltage spikes on input lines. Evaluate the low on-resistance for maintaining signal integrity over longer trace lengths.
