SN74CBT3125PWRE4

Overview

The SN74CBT3125PWRE4 is a digital bus switch IC from the Texas Instruments SN74CBT3125C series. It features four independent single-pole single-throw (SPST) switches in a 14-pin TSSOP package. The device operates with a supply voltage range of 4 V to 5.5 V. Key electrical specifications include a maximum on-resistance of 12 Ohms and a maximum propagation delay of 150 ps. It supports surface-mount installation and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent SPST switches for flexible signal routing
• Enables low on-resistance for efficient signal transmission
• Supports high-speed data transfer with minimal propagation delay

Applications

• Digital bus switching applications
• Signal routing in electronic circuits
• Buffering and driving signals with three-state outputs

Procurement Notes

Verify the complete part number including the RE4 suffix to ensure correct packaging and compliance status. Confirm that the TSSOP-14 package matches your PCB footprint requirements. Check RoHS documentation for environmental compliance details before procurement. Ensure the voltage supply range aligns with your system's power rails.

Selection Notes

Select this component when four independent bus switches are required within a compact surface-mount package. The 14-TSSOP form factor suits space-constrained designs. Verify that the 4V to 5.5V operating voltage range fits your system architecture. Consider the 12 Ohm on-resistance and 150 ps delay for signal integrity requirements.

Part Context

This device belongs to the SN74CBT3125C family of digital bus switches. It is manufactured by Texas Instruments and utilizes ABT technology. The RE4 suffix typically indicates specific tape-and-reel packaging configurations. It serves as a solution for managing multiple signal paths in digital systems requiring isolation or selection capabilities.

Replacement Considerations

SN74CBT3125PWR is a manufacturer-recommended alternative with identical functionality but potentially different packaging or compliance markings. Verify pin compatibility and electrical specifications before substitution.
