SN74CBTD1G125DBVR

Overview

The SN74CBTD1G125DBVR is a single FET digital bus switch IC manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a maximum on-state resistance of 35 Ohms. The device provides a propagation delay of 250 ps, enabling high-speed signal switching. It is housed in a surface-mount SOT-23-5 package with dimensions of 3.05 mm x 1.75 mm x 1.3 mm. The component supports an operating temperature range from -40 °C to +85 °C and complies with RoHS standards.

Feature Summary

• Integrates a single field-effect transistor (FET) for efficient signal path management
• Provides level shifting capability compatible with 5-V tolerant systems
• Delivers rapid signal transmission through ultra-low propagation delay characteristics

Applications

• High-speed data bus switching in communication networks
• Signal translation between different voltage domains in industrial equipment
• Level shifting interfaces in computer peripheral connections

Procurement Notes

Verify the specific suffix 'DBVR' corresponds to the cut tape packaging format rather than reel quantities when sourcing. Confirm the manufacturer designation as Texas Instruments to ensure authenticity. Check for RoHS compliance documentation to meet environmental regulations. Validate the SOT-23-5 physical footprint against PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel bus switch with 5-V tolerance is required. The low on-resistance makes it suitable for maintaining signal integrity in high-frequency applications. Ensure the system voltage remains within the 4.5 V to 5.5 V operational window. Consider the SOT-23-5 package size for space-constrained designs requiring surface mount technology.
