SN74CB3Q3125RGYR Description

Short technical summary and product information.

The SN74CB3Q3125RGYR from Texas Instruments is a high-bandwidth FET bus switch designed for 2.5-V/3.3-V low-voltage applications. It features a high-bandwidth data path capable of up to 500 MHz, making it suitable for demanding signal routing.

 

This device supports bidirectional data flow with near-zero propagation delay and offers low and flat ON-state resistance characteristics. The I/Os are 5-V tolerant, and it can switch signals from 0-V to 5-V with a 3.3-V VCC or 0-V to 3.3-V with a 2.5-V VCC. Its low input and output capacitance minimizes loading and signal distortion.

 

The SN74CB3Q3125RGYR operates over a temperature range of -40°C to 85°C. It is supplied in a 14-VQFN package with surface mount mounting type. The device supports various protocols including Analog, I2C, I2S, JTAG, RGMII, SPI, TDM, and UART, making it versatile for different interface designs.

 

Key electrical characteristics include a typical ON-state resistance of 3 Ohms, a maximum switching frequency of 20 MHz, and a supply current of 0.3 mA typical. It also features robust ESD performance tested per JESD 22 standards.
