SN74CBTLV3125D

Overview

The SN74CBTLV3125D 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-pole single-throw (SPST) switches. The device provides bidirectional data transmission with low on-resistance and minimal propagation delay, ensuring signal integrity across digital buses. Designed for surface-mount applications, it utilizes a 16-pin SOIC narrow package suitable for space-constrained printed circuit board layouts.

Feature Summary

• Provides four independent bidirectional bus switches for flexible signal routing
• Supports low-voltage operation compatible with 2.3 V to 3.6 V power domains
• Features low on-resistance to minimize signal attenuation during transmission

Applications

• Portable equipment requiring low-power signal switching
• Consumer electronics utilizing low-voltage logic interfaces
• Computing products needing high-speed bus isolation

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets required RoHS standards and moisture sensitivity levels for the intended assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when designing systems that require multiple isolated bidirectional paths within a single low-voltage domain. Evaluate the trade-off between the 16-pin package footprint and channel density requirements compared to alternative bus switch families. Confirm that the operating temperature range aligns with the environmental conditions of the final application.
