SN74CBT3383DBR

Overview

The SN74CBT3383DBR is a digital bus switch IC manufactured by Texas Instruments. It features a 5 x 2:2 circuit configuration within a single independent circuit block. The device operates on a single power supply ranging from 4.5 V to 5.5 V. It is housed in a 24-SSOP package with a width of 0.154 inches (3.90 mm). The component supports surface mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional data transmission capability for bus switching applications
• Integrates five independent two-to-two channel switches for flexible signal routing
• Supports low standby power consumption suitable for battery-operated systems

Applications

• Portable equipment requiring efficient bus management
• Consumer electronics utilizing low-voltage logic interfaces
• Computing products needing high-speed data path selection

Procurement Notes

Verify the specific suffix 'DBR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 24-SSOP footprint matches the target PCB design constraints. Ensure the voltage supply aligns with the specified 4.5 V to 5.5 V operational range to maintain signal integrity and prevent device damage during operation.

Selection Notes

Select this component when a single-chip solution is needed for multiple bidirectional bus lines. The 5 x 2:2 architecture offers density advantages over discrete switches. Consider the SSOP package size relative to available board space. Verify compatibility with system voltage levels before integration into the final design.

Part Context

This part belongs to the SN74CBT series of bus FET exchange switches. It serves as a compact alternative to discrete transistor arrays for managing data buses. The device simplifies circuit design by integrating multiple switch channels into one package, reducing overall component count and board area requirements.

Replacement Considerations

SN74CBT3383DBQR is a verified equivalent variant offering identical electrical characteristics but packaged in a reel format instead of tube packaging.
