Product Overview: SN74CB3T1G125DBVR

The SN74CB3T1G125DBVR is a high-performance, single-bit FET bus switch from Texas Instruments, designed with a 5-Ω switch connection between two ports. It is part of the industry-leading SN74 series, which is renowned for its reliability and efficiency in a wide range of applications.

Key Features

  • Low On-State Resistance: The device features a low on-state resistance of typically 5Ω, which minimizes the propagation delay and ensures fast switching performance.
  • Single Bit: It is a single-bit bus switch, which allows for precise control over signal pathways, making it ideal for applications that require individual line switching.
  • 5-V Tolerant Input: The control input is 5-V tolerant, which enables it to be used in mixed-voltage environments and ensures compatibility with a wider range of signal levels.
  • Low Power Consumption: The device is designed for low power consumption, which makes it suitable for battery-operated and power-sensitive applications.
  • High Bandwidth: It offers a high bandwidth (>200 MHz) that allows signals to pass with minimal edge distortion, making it suitable for high-speed data lines.


The SN74CB3T1G125DBVR is versatile and can be used in various applications including, but not limited to:

  • Signal gating
  • Bus isolation
  • Backplane driving
  • Hot board insertion
  • Power routing

Package and Quality

This bus switch comes in a compact SOT-23-5 package, which is ideal for space-constrained applications. Texas Instruments ensures high manufacturing standards, and the SN74CB3T1G125DBVR is no exception. It meets or exceeds the industry's quality norms and is subjected to rigorous testing to guarantee performance and durability.


With its combination of low on-state resistance, high-speed switching, and 5-V tolerant input, the SN74CB3T1G125DBVR is a highly efficient solution for designers looking to optimize their signal routing with minimal power loss and high signal integrity. Texas Instruments' commitment to quality makes this product a reliable choice for both commercial and industrial applications.
