SN74CBTLV3125DR

Overview

The SN74CBTLV3125DR is a low-voltage quadruple FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.3 V to 3.6 V and features four independent single-channel switches in a 1x1:1 configuration. The device utilizes SOIC-14 surface-mount packaging and supports operation temperatures from -40°C to +85°C. Key electrical characteristics include a maximum on-resistance of 12 Ohms, a propagation delay of 150 ps, and a maximum power supply current of 10 uA.

Feature Summary

• Provides four independent single-channel analog or digital signal paths for bidirectional data transmission.
• Enables flexible level shifting between different voltage domains through direct connection to the VCC pin.
• Offers high bandwidth performance suitable for high-speed signal switching applications.

Applications

• Portable equipment requiring low-power signal routing
• Consumer electronics utilizing multiple voltage levels
• Computing products needing efficient bus management

Procurement Notes

Verify the specific suffix 'DR' corresponds to the SOIC-14 tape-and-reel packaging format when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the operating environment remains within the specified temperature range of -40°C to +85°C for reliable performance.

Selection Notes

Select this component for designs requiring low on-resistance and minimal propagation delay in low-voltage systems. It serves as a suitable alternative to standard logic buffers where signal integrity and voltage translation are critical. Consider the package size and channel count relative to board space constraints.
