SN74CBTD3384DBQR

Overview

The SN74CBTD3384DBQR is a digital bus switch integrated circuit manufactured by Texas Instruments. It features a 10-bit FET bus switch architecture with two independent circuits configured as 5 x 1:1 switches. The device operates within a supply voltage range of 4.5 V to 5.5 V, typically at 5 V. Key electrical parameters include a maximum on-resistance of 20 Ohms and a maximum propagation delay of 150 ps. It supports an operating temperature range from -40°C to +85°C and is housed in a 24-pin SSOP package.

Feature Summary

• Integrates ten FET-based bus switches arranged into two independent five-channel configurations for flexible signal routing.
• Provides low on-resistance characteristics to maintain signal integrity across the data bus.
• Features fast switching speeds with minimal propagation delay for high-frequency applications.
• Includes protection mechanisms against negative undershoot voltages to ensure reliable operation.

Applications

• High-speed data bus switching in computer systems
• Signal routing in telecommunications equipment
• Data acquisition systems requiring low-latency switching

Procurement Notes

Verify the specific suffix DBQR corresponds to the 24-pin SSOP package and tape-and-reel or cut-tape availability. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering part number matches the required package style and moisture sensitivity level for your assembly process.

Selection Notes

Select this component when a 10-bit configuration is required rather than octal or hex alternatives. Compare the 20 Ohm on-resistance and 150 ps delay against system timing requirements. Consider the SSOP package dimensions if board space is constrained relative to SOIC or TSSOP options.

Part Context

This part belongs to the SN74CBT series of bus switches designed for 5-V applications. It complements other variants like the SN74CBT3384CDWR which uses a SOIC package. The family focuses on providing low power consumption and high bandwidth for digital signal switching tasks.

Replacement Considerations

SN74CBT3384CDBQR is a verified equivalent offering identical functionality in the same SSOP-24 package. SN74CBTD3384CDWR provides similar performance but utilizes a 24-SOIC package, requiring footprint adaptation.
