SN74CB3T3384PWG4

Overview

The SN74CB3T3384PWG4 is a high-speed TTL-compatible FET bus switch manufactured by Texas Instruments. It features a 10-bit configuration with low ON-state resistance, enabling minimal propagation delay. The device operates within a supply voltage range of 2.3 V to 3.6 V and supports systems using 5-V TTL, 3.3-V LVTTL, and 2.5-V CMOS switching standards. Key electrical parameters include a maximum on-resistance of 8 ohms and a maximum propagation delay of 150 ps. It is housed in a 24-pin TSSOP package and functions as a general-purpose bus switch with two control inputs and level shifting capabilities.

Feature Summary

• Provides voltage translation that tracks the VCC supply voltage for seamless signal path translation between different logic levels.
• Features powered-off protection to prevent current leakage when the device is not energized.
• Offers high bandwidth performance suitable for high-speed data transmission applications.

Applications

• High-speed data bus switching in digital communication systems
• Voltage level translation between 5-V TTL and 3.3-V LVTTL interfaces
• Signal routing in embedded systems requiring low latency

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the package type is TSSOP-24 and ensure the operating temperature range meets system requirements. Check for end-of-life status or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when low on-resistance and fast propagation delay are critical for maintaining signal integrity in high-speed buses. Ensure the supply voltage remains within the 2.3 V to 3.6 V range. Consider the 24-pin TSSOP package constraints for PCB layout. Verify compatibility with both 5-V and 3.3-V logic families if level shifting is required.

Part Context

This part belongs to the SN74CB3T3384 series of high-performance analog switches from Texas Instruments. It is designed for applications requiring fast switching speeds and low power consumption. The series is characterized by its ability to handle multiple channels simultaneously while maintaining signal fidelity across various voltage domains.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as SN74CB3T3384DBQR, ensuring voltage and package compatibility. Verify functional equivalence regarding on-resistance and propagation delay specifications before substitution.
