SN74CB3T3125PWR

Overview

The SN74CB3T3125PWR 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 supports bidirectional data transmission across four independent channels. The device features 5-V tolerant inputs, allowing it to interface with higher voltage logic systems while powered down. It is housed in a 14-TSSOP surface-mount package and is designed for applications requiring signal path translation and powered-off protection.

Feature Summary

• Provides bidirectional data transmission through four independent single-pole single-throw (SPST) switches
• Features 5-V tolerant inputs that enable operation even when the device power supply is off
• Supports signal path translation between different voltage domains

Applications

• Portable equipment requiring low power consumption
• Consumer electronics utilizing low-voltage logic interfaces
• Computing products needing signal translation between voltage levels

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status and ensure the component meets the environmental specifications mandated by the target application's regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require switching signals between 2.3-V and 3.6-V domains while maintaining compatibility with 5-V control logic. Ensure the design accommodates the 14-TSSOP footprint and thermal characteristics suitable for surface-mount technology integration in space-constrained layouts.

Part Context

This part belongs to the SN74CB3Q3125 family of low-voltage quadruple FET bus switches. It shares functional similarities with other members like the SN74CB3T3125PW but differs in packaging configuration. The series is engineered for high-speed data routing in portable devices where power efficiency and signal integrity are critical design constraints.

Replacement Considerations

SN74CB3T3125PW serves as a parameter-equivalent alternative available in tube packaging.
